Bearing Preload | National Precision Bearings

The purpose of preload in a bearing system is to eliminate clearance that is designed into standard ball bearings. Almost all radial ball bearings are made with a clearance or space between their components to allow for free movement. This space, if not taken up by a preload can allow the rolling elements to slide rather than roll, or even

Tapered roller bearings | FV BEARING

FV taper roller bearings have the rolling elements under the form of frustum of cone. They roll on tapered surface which, if extended, converges towards a single point on the bearing axis. The rollers are guided tangentially by the cage and axially by the big rib of the inner ring, on which they have contact.
