Reference type detail is a type of ball bearing with aligning of shaft and housing. According to  the construction of the inner ring and outer ring of the reference type detail,it can aligning rotate. Because the outer ring has a spherical raceway and its centre of curvature coincides bearing; therefore, the axis of inner ring,balls,cage can deflect to some extend around the bearing center. Reference type detail can be used in many special industry such as precision instrument, low noisy motor, automobile, metallurgy and so on.


Product Features and Benefits:

1)High quality Steel - Ultra clean steel to extend bearing life by up to 80%.

  Pressed steel and polyamide cages available.

2)Advanced Grease Technology - Bearing Brand lubricants that can extend grease life and performance.

3)High Grade Balls - Quiet and smooth operation even at high speed.

4)Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.

5)Sealed versions available

Dynamic misalignment of up to 7 degree can be accomodated.

3)Self-aligning Ball Bearing has  two kind of bores, one is cylindrical bore,the other is tapered bore. Tapered bore of self-aligning ball bearing’s conical degree is 1:12 or 1:30.In the aim to strength the Self-aligning ball bearing’s lubrication,process a annular oil groove or three oil bores in the outer ring of the bearing.


Reference type detail can withstand large radial loads ,it can also withstand axial load at same time.The bearing can be work when the axial stress bending or leaning and make the center line of the center line of the inner ring and outer ring relative tilt is not more than 1 ° ~ 2.5 °.Self-aligning ball bearing can be used in many special industry such as precision instrument, low noisy motor, automobile, metallurgy and so on.
