Precision high speed ball bearings Four Point QJ218 double row bearing

1. Angular Contact Bearing Specification :

2. Angular contact ball bearings features ​​:
Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC-type (α = 25 °) and 7000B (α = 40 °) of several types. The kinds of bearings in the outer ring lock port, the general separation of inside and outside the ring can not be combined radial and axial load and axial load in one direction. Axial load capacity of the decision by the contact angle, contact angle is greater, the ability to withstand high axial loads. This kind of bearing shaft or housing to limit axial displacement in one direction.

3. The type of angular contact ball bearing

Single Row Angular contact ball bearing: 7100series, 7200series, 7300series, 7400series
Double Row Angular contact ball bearing: 52series, 53series,3200series,3300series
