The clutch pedal is the control mechanism which deactivates or activates the clutch component. A clutch is what allows the wheels and engine to be connected. If you step on the clutch pedal, the wheels and engine become disconnected from each other. The clutch release bearing helps make this disconnection possible.

Now you may wonder why you’d ever want to release the engine from the wheels. Think about when you slow down to a complete stop at a stop light or stop line. Even though your wheels are not moving, your engine is still running. If you don’t disconnect the running engine from the wheels as you slow down to a stop, then your engine will shut off. That way, your engine can continue spinning while your wheels stay motionless.

As you step on the brake pedal, the clutch release bearing moves toward the flywheel. The nearby pressure plate has release fingers which then get pushed into the strong spring, resulting in the wheels and engine becoming disconnected. If the clutch release bearing were to get worn out, damaged, or malfunction in some way, then it would disrupt the entire disconnection process. This will result in your car engine shutting off because of your inability to disengage the clutch.

One Way Clutch bearings or Sprag style bearings are constructed from a drawn cup with needle roller clutches and have a small radial section height. They are often called One Way Bearings, Anti-Reverse Bearings and Clutch bearings. The units are compact, lightweight and operate directly on a shaft; they are also suitable for transmitting high torque. Boca Bearings offers Standard and Stainless Steel one way clutch bearings as well as OWC style One Way bearings in standard and stainless steel, EWC Hex one way bearings, and CSK Sprag Type one way bearings available with avaialbe keyway options for higher torque capabilities.

One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric series.

Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

SKF manufactures standard and customized slewing bearings in various designs, with outside diameters from 0,1 to 18 m to meet the demands of particular applications.

SKF pillow (plummer) block ball bearing units consist of an insert bearing mounted in a housing, which can be bolted to a support surface. The SKF assortment includes units compliant with ISO standards, North American standards, or Japanese Industrial Standards (JIS). Within the SKF assortment, you can find units for nearly all requirements. 

In addition, SKF Food Line ball bearing units provide hygienic and high-performance bearing unit solutions for the most demanding food and beverage environments

Stainless steel deep groove ball bearings (fig. 1) are corrosion resistant when exposed to moisture and several other media. They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces (fig. 2).

These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.

A pillow block bearing (or plummer block) is a pedestal used to provide support for a rotating shaft with the help of compatible bearings and various accessories. The assembly consists of a mounting block which houses a bearing.^[1] The block is mounted to a foundation and a shaft is inserted allowing the inner part of the bearing / shaft to rotate.^[1] The inside of the bearing is typically 0.001 inches (0.025 mm) larger than the shaft to ensure a tight fit.^[2] Set screws, locking collars, or set collars are commonly used to secure the shaft.^[2] Housing material for a pillow block is typically made of cast iron^[1] or cast steel.

A pillow block usually refers to a housing with an included anti-friction bearing, wherein the mounted shaft is in a parallel plane to the mounting surface, and perpendicular to the center line of the mounting holes, as contrasted with various types of flange blocks or flange units. A pillow block may contain a bearing with one of several types of rolling elements, including ball, cylindrical roller, spherical roller, tapered roller, or metallic or synthetic bushing.^[1] The type of rolling element defines the type of pillow block. These differ from "plummer blocks" which are bearing housings supplied without any bearings and are usually meant for higher load ratings and a separately installed bearing.^[1] Plummer block bearings are designed for more corrosive environments.^[1]

The fundamental application of both types is the same, which is to mount a bearing safely enabling its outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings may be either split type or solid type.^[1] Split type housings are usually two-piece housings where the cap and base may be detached,^[1] while solid are single-piece housings.^[1] Various sealing arrangements may be provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the environmentally sensitive bearing to rotate free from contaminants while also retaining lubrication, either oil or grease, hence increasing its performance and duty cycle.

Bearing housings are usually made of grey cast iron.^[1] However, various grades of metals can be used to manufacture the same, including ductile iron, steel, stainless steel, and various types of thermoplastics and polyethylene-based plastics. The bearing element may be manufactured from 52100 chromium steel alloy (the most common), stainless steel, plastic, or bushing materials such as SAE660 cast bronze, or SAE841 oil impregnated sintered bronze, or synthetic materials.

Other information:

• Sleeve bearings are a kind of plain bearing--that is, bearings with few moving parts. Many spherical ball bearings have an internal ring, which is lined with smaller balls inside. In contrast to regular ball bearings, a sleeve bearing only has two moving parts; the outer sleeve and the inner rotating cylinder. They are also known as journal bearings, after the technical term for the outer sleeve. The outer journey of a sleeve bearing may be whole, split, or clenched between the two halves
• Sleeve bearings can be made of compressed powdered metal, such as bronze or copper. Because of the material from which they are made, the metal is microscopically porous. When they are oiled on the outside, the oil will be drawn up through the pores to lubricate the inner cylinder. A sleeve bearing can be lubricated in a number of ways besides oiling. Sometimes, molten metal or graphite is used. Some man-made polymers can lubricate moving parts without seizing up in extremely cold temperatures. Other sleeve bearings are surfaced with porous, oiled hardwood so that the oil will be drawn up into them more readily

Additional information:

• Though they are self-lubricating, sleeve bearings often fail through lack of lubrication. The inner bearing might wear away at the sleeve until the space is no longer perfectly cylindrical. This may cause the bearing to shake when it moves, adversely affecting the movement of the mechanism. Other times, there may not be enough lubricant, or the lubricant may become viscous through adverse temperature conditions. When there is not enough lubrication, the bearing will cease to move. Due to these issues, sleeve bearings are often elaborately shielded from dust and dirt by seals. A designer or mechanic needs to carefully consider where a sleeve bearing will be located in a machine before using it. They are criticized for being more finicky than ball bearings in that inadequate lubricant will cause them to come to a complete stop rather than wear down gradually over time

The flat rectangular air bearing stands alongside the flat round air bearing as one of our original New Way^® products, and this product line is still going strong today. The flat rectangular air bearing moves across the guide surface on a 5 micrometer, thin layer of air and enables truly Frictionless Motion.

The natural permeability of carbon provides a more even distribution of air, offering superior performance unavailable to conventional- and orifice-based bearings.

The popularity of Flat Round Air Bearings is due to their versatility. They can be used in both linear and rotary motion applications. The bearings are shaped like a hockey puck and have a porous carbon substrate on one side. Air is forced through the carbon and must pass through the naturally winding pathways to reach the bearing surface. This journey results in a stiff, uniform cushion of air on the bearing face, creating our reliable no-contact, Frictionless Motion. These bearings can also come vacuum preloaded which increases their positioning precision.

Radial air bearings provide non-contact support for rotating, round artifacts using a thin (5µm) layer of air. This thin air layer is amazingly stiff, creating a stable support for a ring, or bearing surface, while allowing for surface speeds of up to 50 meters-per-second.

New Way radial air bearings can be configured to ride on the outer diameter or inner diameter of a rotating artifact for a given application, using concave and convex shapes using a radius cut along the length (L) or width (W) of the bearing, depending on your structural requirements. The bearings are specifically machined to the tight tolerances necessary to create non-contact motion.

The Modular Air Bearing design subdivides motion systems into smaller installable parts. They can be independently installed and then used in different systems and shapes. Modular Air Bearings make use of industry standards for interfaces.

Axial cylindrical roller bearings have a high axial load carrying capacity, are extremely rigid and can support axial forces in one direction. Axial cylindrical roller bearings have a greater load carrying capacity than axial needle roller bearings with the same bearing diameter.

Wide inner ring bearings, also known as extended inner ring ball bearings, are designed for special applications where the width of the inner ring is higher than the width of the outer ring. These bearings provide additional shaft support and can be locked to the shaft using set screws or an eccentric self-locking collar. They are available in cylindrical, spherical, and relubricated versions. The inner ring can be extended without a flange or with a flange, and they can be made from various materials such as chrome steel, stainless steel, or hybrid ceramic.
