Bearings • Roller Bearings
Roller bearings is a type of rolling element bearing. They use cylinders that are greater in length than the diameter. Relative to ball bearings, roller bearings have higher radial load capacity. They have low axial load capacity and higher friction. Also in comparison to ball bearings, the bearing capacity of roller bearings can decrease at a faster rate if the inner and outer races are not aligned properly. Common types of roller bearings include cylindrical, spherical, tapered, and needle. They are ideal for heavy-duty and moderate-speed functions. But cylindrical bearings have lower speed capabilities.

Berliss are manufacturers of a variety of roller bearings designed for varying dynamic and static loads and are available in nearly 4,000 sizes in high carbon, low carbon, stainless steel, and nylon. They come with solid inner and outer races, split outer races, in inch and metric dimensions, and in flanged, caged two piece, caged three piece and roller assembly configurations. Tapered roller bearings are available in single row and double row designs, in a wide variety of sizes, and with bronze or steel cages. They are capable of handling heavy combinations of radial and thrust loads. Needle bearings offer high load carrying, come in stainless steel or chrome steel, and either caged or full compliment. Cam followers are also available.
AST are suppliers of roller bearings, bushings, rod ends and custom sub-assembly products. They offer tapered roller bearings consisting of tapered rollers and a cage. The cone, cup and rollers carry the load while the cage spaces and retains the rollers on the cone. Configurations available include single row, double row and four row. They are made of high carbon chrome steel and come in both metric and inch sizes. Other products include miniature, spherical plain, tapered flanged, single row radial and double row bearings.
