Detailed Product Description
Material: Steel Copper Color: Any
Type: Plain Bearing Rolling Element Bearing Jewel Bearing

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vector of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.

plain bearing

Rubbing surfaces, usually with lubricant; some bearings use pumped lubrication and behave similarly to fluid bearings.

Rolling element bearing

Ball or rollers are used to prevent or minimise rubbing.Rolling element bearing life is determined by load, temperature, maintenance, lubrication, material defects, contamination, handling, installation and other factors. These factors can all have a significant effect on bearing life.Bearing Ball Bearing Cylindrical roller bearing Niddle Roller Bearing Metric Bearing

Jewel bearing

Off-center bearing rolls in seating

Magnetic bearings

Faces of bearing are kept separate by magnets

Flexure bearing

Material flexes to give and constrain movement

Composite bearing

Plain bearing shape with PTFE liner on the interface between bearing and shaft with a laminated metal backing. PTFE acts as a lubricant.

Many bearings require periodic maintenance to prevent premature failure, but many others require little maintenance. The latter include various kinds of fluid and magnetic bearings, as well as rolling-element bearings that are described with terms including sealed bearing and sealed for life. These contain seals to keep the dirt out and the grease in. They work successfully in many applications, providing maintenance-free operation. Some applications cannot use them effectively.
