Basic Knowledge of Bearings

Rolling Bearing: 

A bearing that provides rolling motion between parts supporting loads and moving relative to each other. It consists of parts with raceways and rolling element assemblies with or without separators or guides. It can be used to bear radial, axial, or combined radial and axial loads.

Angular Contact Bearing: 

A rolling bearing with a nominal contact angle between the balls and races greater than 0° but less than 90°.

Spherical Outer Race Bearing: 

A radial rolling bearing with a spherical outer race and a wide inner ring with locking devices. It is primarily used for simple housings.

Linear Motion Bearing: 

A rolling bearing in which the two raceways have relative linear motion in the direction of rolling.

Ball Bearing:

A rolling bearing with balls as rolling elements.

Deep Groove Ball Bearing: 

A radial ball bearing in which each ring has a continuous raceway groove with a cross-section approximately one-third the circumference of the ball.

Thrust Ball Bearing: 

A thrust rolling bearing with balls as rolling elements.

Roller Bearing: 

A rolling bearing with rollers as rolling elements.

Cylindrical Roller Bearing: 

A radial rolling bearing with cylindrical rollers as rolling elements.

Tapered Roller Bearing:

A radial rolling bearing with tapered rollers as rolling elements.

Needle Roller Bearing: 

A radial rolling bearing with needle rollers as rolling elements.

Spherical Roller Bearing:

A self-aligning radial rolling bearing with convex or concave spherical rollers. Bearings with convex spherical rollers have a spherical raceway in the outer ring, while those with concave spherical rollers have a spherical raceway in the inner ring.

Thrust Roller Bearing: 

A thrust rolling bearing with rollers as rolling elements.

Thrust Cylindrical Roller Bearing:

A thrust rolling bearing with cylindrical rollers as rolling elements.

Thrust Tapered Roller Bearing: 

A thrust rolling bearing with tapered rollers as rolling elements.

Thrust Needle Roller Bearing: 

A thrust rolling bearing with needle rollers as rolling elements.

Thrust Spherical Roller Bearing: 

A self-aligning thrust rolling bearing with convex or concave spherical rollers. Bearings with convex spherical rollers have a spherical raceway in the bearing seat ring, while those with concave spherical rollers have a spherical raceway in the bearing shaft ring.

Pillow Block Bearing: 

A unit that combines a radial bearing with a housing, featuring a base plate with mounting screws on a support surface parallel to the bearing axis.

Spherical Plain Bearing: 

A spherical sliding bearing with sliding contact surfaces, primarily suitable for oscillating, tilting, and rotating movements.

Combined Bearing:

A rolling bearing that incorporates two or more of the above-mentioned bearing structures within a single set. Examples include combined bearings of needle rollers and thrust cylindrical rollers, needle rollers and thrust balls, and needle rollers and angular contact balls.

Other Bearings: 

Rolling bearings with structures other than those mentioned above.
