Single row deep groove ball bearing
Single row deep groove ball bearing is the most representative structure of rolling bearing and has a wide range of applications.In addition to bearing radial load, it can also bear axial load in second directions.Small friction torque, most suitable for the applications of high speed rotation, low noise, low vibration.This kind of bearings, in addition to the open type, also had the type of bearings with a steel dust cap, bearings with a rubber sealing ring, or bearings with a stop ring on the outside diameter of the outer ring.In general, use pressed sheet-steel cage. Deep groove ball bearings, large bearings are use copper alloy car cage.A car cage is also used for high speed rotations.
Extra small ball bearing and miniature ball bearings
There are two basic types of miniature and instrumental ball bearings: deep groove ball bearings and angular contact ball bearings.Deep groove ball bearings can be further divided into following five types according to the detailed design:The standard form,The flanged outer ring type, the extended inner ring type, the extended type which the radial thickness of the outer or inner ring is much wider than ordinary bearings, the thin type which both the inner and outer radials are very thin.Deep groove ball bearings can also be classified into "open type", "dust cover type" and "sealing circle type" according to the form of sealing or dust proof.
Full ball bearings crowded ball bearing
Full ball bearings, due to the design of the ball filler in inner ring and the outer ring, it can filled more balls than deep groove ball bearings .It is not suitable for large axial load because it had the ball filler.The type BL2 and type BL3 is the same size with type 62 and type 63 single row deep groove ball bearing in main item.We also have steel dust cap ZZ type except open type.On the other hand,when use the bearings, the ball filling position of the outer ring shall be regarded as the non-load ring as much as possible.The retainer is a punch retainer.
Magneto ball bearings
The inner ring groove is slightly shallower than the deep groove ball bearing. The inner diameter of the outer ring without retaining side is cylindrical from the bottom of the outer ring. The outer ring can be separated to facilitate bearing installation.Normally, two bearings are used opposite each other.This kind of bearings are small bearings with internal diameters of 4-20mm.Mainly used for small generators, gyroscopes, measuring instruments.Generally using copper alloy stamping cage.
