Press the bearing structure type classification
(1) can bear the load bearing according to the direction or different nominal contact angle, divided into:
A) 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.
2) ---- thrust bearing is mainly used 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 bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.
(2) The rolling bearing according to the types, divided into:
1) 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.
(3) whether the bearing aligning their work, divided into:
A) 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.
(4) rolling bearing according to the number of columns, divided into:
1) having a single bearing ---- rolling bearing;
2) ---- double row bearings with two rows of rolling elements of the bearing;
3) multi-row bearings ---- with more than two rolling element bearings, such as three, four bearings.
(5) bearing their parts can detach, divided into:
1) Bearing ---- separable bearings with separable components;
2) non-separable bearings ---- bearings in the final package, the ring can not be separated any free bearings.
(6) bearing their structural shapes (eg with or without filling slot, with or without inner and outer rings and rings shape, wall structure, even without the cage, etc.) can also be divided into a variety of structural types.
