① double row angular contact ball bearings-can withstand both radial and biaxial axial loads, 30 degrees of contact angle;
② self-aligning Ball Bearings-double row steel ball, outer ring Raceway is the inner spherical shape, with automatic adjustment of the heart performance, mainly bearing radial force;
③ Spherical roller bearings-similar to self-aligning ball bearings, have higher bearing capacity;
④ Tapered roller bearings-can withstand both radial and unidirectional axial loads, with large carrying capacity, usually in pairs;
⑤ needle Bearing--can only withstand the radial load, bearing capacity, radial size is very small, generally no cage;
⑥ thrust ball bearings-can only withstand axial load, the limit speed is low, the ring can be separated;
⑦ deep groove ball bearings--the structure is simple, mainly by radial load, can also withstand a certain two-way axial load, friction coefficient is small, inexpensive, the application of the widest range;
⑧ angular contact ball bearing-can withstand both radial and unidirectional axial load, contact angle of 15 degrees, 25 degrees and 45 degrees three species;
⑨ thrust cylindrical roller bearings-can withstand a larger unidirectional axial load, high axial stiffness, low limit speed, not allow axial and outer axis of the tilt;
⑩ cylindrical roller bearings-to withstand larger radial loads, the inner and outer rings can be freely axially moved and cannot withstand axial loads.
