Roller Bearings

Roller Bearings

Online Bearing Store supplies a large variety of roller bearings and needle roller bearings. Roller bearings are any cylindrical or spherical object that aids in the movement of an object greater in size than the bearing itself. They are weight distribution-oriented bearings; this means they utilize many points of contact between a circular housing that contains the internal rolling elements, such as ball bearings, that sit within a collar. These bearing systems use the decrease in rolling resistance as a means of increasing the efficiency of moving an object. Roller bearings typically fall within three categories: cylindrical, tapered, and needle.

Types of Roller Bearings

Needle: Bearings similar to cylindrical roller bearings except that they utilize small cylindrical rollers with lengths 3 to 10 times their diameter. These bearings have a high radial load capacity and are best suited for applications in which radial space is minimal.

Drawn Shell Cup Needle Roller Bearings: Bearings which have a high length-to-diameter ratio that may be lubricated with grease or oil-based lubricants. Commonly used in applications such as agriculture equipment, engines, and small appliances. Bearings Direct supplies both metric and inch size drawn shell cup needle rollers.
