(1) High positioning accuracy, high repeatability The PMI linear guideway is a design of rolling motion with a low friction coeffcient, and the difference between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making. (2) Low frictional resistance, high precision maintained for long period The frictional resistance of a linear guideway is only 1/20th to 1/40th of that in a slide guide. With a linear guideway, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for longperiod. (3) High rigidity with four-way load design The optimum design of geometric mechanics makes the linear guideway to bear the load in all four directions, radial, reversed radial, and two lateral directions. Furthermore, the rigidity of linear guideway could be easily achieved by preloading carriage and by adding the number of carriages. (4) Suitable for high speed operation Due to the characteristic of low frictional resistance, the required driving force is much lower than in other systems, thus the power consumption is small. Moreover, the temperature rising effect is small even under high speed operation. (5) Easy installation with interchangeability Compared with the high-skill required scrapping process of conventional slide guide, the linear guideway can o!er high precision even if the mounting surface is machined by milling or grinding. Moreover the interchangeability of linear guideway gives a convenience for installation and future maintenance. 

Linear actuators are a type of actuator that convert rotational motion in motors into linear or straight push/pull movements. Linear actuators are ideal for all types of applications where tilting, lifting, pulling or pushing with pounds of force are required. Electric linear actuators are often the preferred solution when you need simple, safe and clean movement with accurate precision and smooth motion control. LINAK created the first electric linear actuator in 1979 and has led the industry in linear movement ever since.

Thrust bearings come in several varieties.

• Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load.
• Cylindrical thrust roller bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to wear due to the differences in radial speed and friction which is higher than with ball bearings.
• Tapered roller thrust bearings consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing. The length of the roller and the diameter of the wide and the narrow ends and the angle of rollers need to be carefully calculated to provide the correct taper so that each end of the roller rolls smoothly on the bearing face without skidding. These are the type most commonly used in automotive applications (to support the wheels of a motor car for example), where they are used in pairs to accommodate axial thrust in either direction, as well as radial loads. They can support greater thrust loads than the ball type due to the larger contact area, but are more expensive to manufacture.

A roller screw is a mechanical actuator similar to a ball screw that uses rollers as the load transfer elements between nut and screw instead of balls. The rollers are typically threaded but may also be grooved depending on roller screw type. Providing more bearing points than ball screws within a given volume, roller screws can be more compact for a given load capacity while providing similar efficiency (75%-90%) at low to moderate speeds, and maintain relatively high efficiency at high speeds. Roller screws can surpass ball screws in regard to positioning precision, load rating, rigidity, speed, acceleration, and lifetime. Standard roller screw actuators can achieve dynamic load ratings above 130 tons of force (exceeded in single-unit actuator capacity only by hydraulic cylinders).

The three main elements of a typical planetary roller screw are the screw shaft, nut and planetary roller. The screw, a shaft with a multi-start V-shaped thread, provides a helical raceway for multiple rollers radially arrayed around the screw and encapsulated by a threaded nut. The thread of the screw is typically identical to the internal thread of the nut. The rollers spin in contact with, and serve as low-friction transmission elements between screw and nut. The rollers typically have a single-start thread with convex flanks that limit friction at the rollers' contacts with screw and nut. The rollers typically orbit the screw as they spin (in the manner of planet gears to sun gear), and are thus known as planetary, or satellite, rollers. As with a lead screw or ball screw, rotation of the nut results in screw travel, and rotation of the screw results in nut travel.

For a given screw diameter and quantity of thread starts more rollers corresponds to higher static load capacity, but not necessarily to a higher dynamic load capacity. Preloaded split nuts and double nuts are available to eliminate backlash.

What is an Incremental Encoder? An incremental encoder is a type of encoder device that converts angular motion or position of a shaft into an analog or digital code to identify position or motion. Incremental encoders are one of the most commonly used rotary encoders.

Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.
basic purpose of a solenoid coil is to convert electrical energy into mechanical energy to supply linear motion. The structure of a solenoid coil includes a coil of wire that is wrapped around a piston made of a ferromagnetic metal.
Solenoid works on the principle of electromagnetism. When the electric current passes through the coil, the magnetic field is generated. When a metal core is placed inside the coil, the magnetic lines of flux are concentrated on the core. This increases the induction of the coil as compared to the air core.
An electric current through the coil creates a magnetic field. The magnetic field exerts an upwards force on the plunger opening the orifice. This is the basic principle that is used to open and close solenoid valves.

The two main classes of linear bearings are rolling and plain linear bearings. Rolling linear bearings consist of rolling elements within their housing; this facilitates linear motion. Their rolling elements may be recirculating or non-recirculating.linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction.Linear bearings are used in machine-tool ways, in sliding doors, 3D printers, and in a variety of automation settings where reducing friction and guiding linear motion is needed.Linear motion bearings are bearings that are made to move in a particular direction, and they come in a wide array of different designs. Some linear slides are motorized, others are not. Examples of the former include roller and XY tables as well as machine and dovetail slides.

Linear Guideway is one of the important elements of the machine tool. Its main function is to make sure that the cutting tool or machine tool element moves along a predetermined path. LM Guide provides smooth and linear motion in machine tools, due to which higher accuracy and precision can be obtained

Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. Ballscrews convert rotary motion into linear motion, and are most commonly used in industrial machinery and precision machines. Hiwin Corporation provides a wide range of ballscrew configurations to satisfy your special application requirements. Hiwin has the capability of producing JIS C0 class ground ballscrews, and DIN 5 class (up to 23 microns) for precision rolled ballscrews.

A ball screw (or ballscrew) is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw. In contrast to conventional leadscrews, ballscrews tend to be rather bulky, due to the need to have a mechanism to recirculate the balls.

Another form of linear actuator based on a rotating rod is the threadless ballscrew, a.k.a. "rolling ring drive". In this design, three (or more) rolling-ring bearings are arranged symmetrically in a housing surrounding a smooth (threadless) actuator rod or shaft. The bearings are set at an angle to the rod, and this angle determines the direction and rate of linear motion per revolution of the rod. An advantage of this design over the conventional ballscrew or leadscrew is the practical elimination of backlash and loading caused by preload nuts.

Matching up with the ever increasing requirements of the customers, we are engaged in providing Cross Roller Guide.

Ball transfer units are omnidirectional load-bearing spherical balls mounted inside a restraining fixture. They are identical in principle to a computer trackball (pointing device). Typically the design involves a single large ball supported by smaller ball bearings.

They are commonly used in an inverted ball up position where objects are quickly moved across an array of units, known as a ball transfer table, a type of conveyor system. This permits manual transfer to and from machines and between different sections of another conveyor system.^[1] They are used in airports for luggage delivery, or in industry as part of manufacturing systems. Prior to the invention of the ball transfer unit, first patented by Autoset Production Ltd in 1958,^[2] these applications were solved by the use of inverted casters. However, casters recognise a trail, meaning that the wheels had to align before directional change could be achieved.

Ball transfer units can also be used in a non-inverted ball down position as a type of caster, however this use is restricted by load-bearing limitations and the type of floor. Manufacturers have addressed this problem with ball transfer units incorporating recirculating ball principles, however the inverted position is still the most common application and the least problematic.

We bring forth vast industrial experience and expertise in this business, involved in offering a high-quality range of Linear Motion Bearing.

The inner surface of the outer cylinder is finished by precision grinding, resulting in smooth motion of the ball elements. Each of the ball elements is held in a separate hole and smooth motion is achieved for both rotational motion and linear motion. The retainer moves half the length of the linear motion, therefore, the stroke length is limited to approximately twice the length the retainer can travel within the outer cylinder. The actual stroke should be limited to 80% of the maximum stroke as listed in the dimension tables.

High Precision

• High-carbon chromium bearing steel is used for the outer cylinder. It is heat treated and ground to achieve high rigidity and accuracy.
