S V Hi-Tech Bearing (India) Private Limited

IKO designs and develops compact roller bearings for use in heavy-duty machinery such as construction equipment and industrial machines. Three styles are available for different applications: caged, full complement and roller bearings for sheaves. Compact footprint, similar to needle roller bearings

the different types of needle bearings?There are three main types of drawn cup needle bearings, drawn cup with a cage and open ends, drawn cup with a cage and one closed end, and full complement bearings with open ends. Roller and cage assemblies consist of needle rollers contained by a cage or retainer.
needle bearing used for?Needle bearings are a small cylindrical type of roller bearings which are used to prevent friction between moving surfaces which have low rotational speeds. Needle roller bearings are usually used when space is at a premium as needle bearings are much more compact than ball bearings.

With only a few exceptions, the cages are made from sheet steel. Bearings with a plastic cage have the suffix “TV.” The outer ring of a needle bearing can be stamped steel or hardened steel depending upon the type, where rollers are made from hardened steel.

SKF needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.

SKF supplies needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.

Alignment needle roller bearings have an outer ring with a sphered (convex) outside surface. Two polymer seating rings with a sphered (concave) inside surface are encased in a drawn sheet steel sleeve and fitted over the outer ring.

Axial/radial roller bearings for screw drives are double direction, high precision axial cylindrical roller bearings with a radial bearing component.

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.
