BEARING - BRONZE GEAR BEARINGS

Bearings are widely used in restaurant equipment. They limit motion and reduce friction between moving parts. A bearing may provide for free linear or rotational movement of the part. Bearings are classified broadly according to the type of operation, the motion allowed, or to the direction of the load applied to the parts.

A gear or cogwheel is a rotating machine part having cut teeth or, in the case of a cogwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation.
