Single row deep groove ball bearings rolling bearings in the most representative structure, a wide range of USES. In addition to bearing radial load, it can also bear axial load in two directions of e .Small friction torque, most suitable for high speed rotation, low noise, low vibration .In addition to the open bearings, there are bearings with steel plate dust cover, bearings with rubber seal ring, or bearings with a stop ring on the outer ring diameter. Generally they adopt steel plate stamping cage .Large - scale bearings are made of copper alloy cage. Car cage is also used for high speed rotation

Miniature and instrument ball bearings in two basic types: deep groove ball bearings, angular contact ball bearings, deep groove ball bearings and can be further divided into the following five types: according to the detailed design standard, the flange outer ring type, wide inner ring, the radial thickness of the outer or inner ring is much bigger than the ordinary bearings type extension, both inside and outside the ring radial very thin thin.Deep groove ball bearings can also be sealed or dustproof in the form of open type, dustproof cover type and sealing ring type

Single row angular contact ball bearings have contact angles and are therefore suitable for bearings axial or composite loads in one direction .In structure, axial separation occurs after bearings radial load. Therefore, two bearings are used in pairs, or more than two bearings are used in a pair. Single-row angular contact ball bearings, which can be preloaded to improve rigidity, are therefore suitable for high-precision machine tool spindles, etc.In general, angular contact Angle bearings retainers with contact angles of 30 degrees (code A) and 40 degrees (code B), according to table 1.However, synthetic resin cage or polyamide cage are also used according to different conditions

Single row angular contact ball bearings back-to-back double, inner ring, outer ring into a single structure .It can bear axial load in two directions and has torque load capacity. It can be used as fixed end bearings. Use a press cage

Point contact ball inner ring is divided into two, with a bearings can bear two directions of axial load. Contact Angle of 35 degrees axial load capacity, suitable for the pure axial load, or large axial load composite load .The cage is made of copper alloy

The self-aligning ball bearings is suitable for driving shaft with difficult center and easy deflection of shaft. It Should be small contact Angle, so the axial load capacity is also small, generally used stamping retaining plate. The adjustable Angle allowed for ball bearings under normal load is about 0.07 to 0.12 radians .Depending on the mounting dimensions around the bearings, there are also special cases where this alignment Angle cannot be reached

Thrust ball bearings by single and two - way two types. One-way thrust ball bearings is composed of two rings and a cage with a ball. Bidirectional thrust ball bearings is composed of three rings and two cages with balls. If it is bidirectional, it takes the form of two retainers with a ball clamped on the shaft ring
