definitions: rm ... zz rm .. 2rs series double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment loads, mainly for bi-axial shaft and housing restrictions displacement member.
application: compared with single bearing double row angular contact ball bearings with better rigidity to withstand the overturning moment. bearing non-split. there are especially suitable for applications where high rigidity requirements. front wheels are widely used in cars (some models also use the same size double row tapered roller bearings).
features: double row angular contact ball bearings, the outer ring can be tilted between finite, allowing the tilt angle depends on the internal clearance of the bearing, bearing size, interior design and the forces and moments acting on the bearing, and the maximum allowable tilt angle should be guaranteed not to generate excessive additional stress in the bearing.
if the bearing inner and outer angle of inclination between, will affect bearing life, while resulting in decreased precision bearings running, running noise increases. double row angular contact ball bearings generally use nylon cage or solid brass cage. when double row angular contact ball bearings installed should be noted that although the bearings can withstand axial load, but if one side of the ball gap, you should be careful not to let the main axial load through the notched side of the gutter. should pay attention to the bearings in the side without the ball gap to bear the main load raceway.
double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment loads, it can limit the bi-axial displacement of shaft or housing, the contact angle of 30 degrees.
another double row angular contact ball bearings also has good rigidity to withstand the overturning moment. bearing non-split. there are especially suitable for applications where high rigidity requirements. widely used in cars in the front wheel hub.
