Rolling bearings - Classification

One, can withstand the load bearing their direction, or different nominal contact angle, divided into:
Radial bearings
Radial bearings ---- mainly used to bear radial load bearing, its nominal contact angle from 0 to 45. At different nominal contact angle, is divided into: radial contact bearings ---- nominal contact angle of 0 radial bearings: Radial angular contact bearings ---- nominal contact angle greater than 0-45 of radial bearings.
Thrust bearing ---- mainly for axial load bearing, its nominal contact angle greater than 45-90. Press the nominal contact angle is divided into different: axial contact bearings ---- nominal contact angle of 90 thrust bearings: Axial angular contact bearing manufacturer ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.
A ball bearing ---- the ball rolling:
2, roller bearing ---- rolling as rollers. Roller Bearing press roller types are divided into: cylindrical roller bearings ---- rolling body is cylindrical roller bearings, cylindrical roller length to diameter ratio of less than or equal to 3; needle bearing ---- rolling body is a needle roller bearings, needle length to diameter ratio greater than 3, but the diameter is less than or equal to 5mm; tapered roller bearings ---- rolling body is tapered roller bearings; aligning roller bearings eleven rolling body is spherical roller bearings.
Bearing aligning their work ability, divided into:
1, self-aligning bearing ---- raceway is spherical in shape, able to adapt to two raceways angular misalignment between the axis line and angular movement of the bearing.
2, non-aligning bearing (rigid bearing) ---- can impedance raceway of the bearing axis line angle offset.
Rolling bearing according to the number of columns, divided into:
Rolling
1, single bearing ---- with a rolling element bearings.
2, the double row bearing ---- with two rows of rolling elements bearings.
3, multi-row bearings ---- with more than two rolling element bearings, such as three, four bearings.
