Double row angular contact ball bearings application:

Double row angular contact ball bearings: pump, blower, air compressor, various types of transmission, fuel injection pumps, printing machinery.

Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, limit the axial displacement of the axis.
Main member for limiting bi-directional axial displacement of the shaft and housing.

Double row angular contact ball bearings between the outer ring can be tilted, allowing the tilt angle depends on the internal clearance of the bearing, the bearing size, internal design and effect on the bearing force and torque, while the maximum allowable tilt angle should ensure that bearing will not generate excessive additional stress. If the bearing inner and outer rings between the angle of inclination, it will affect the life of the bearing, also causing the bearings running accuracy decreased, increased running noise.

Double row angular contact ball bearings generally use nylon cage or solid brass cage. Double row angular contact ball bearings installed should note that the bearings can withstand two-way axial load, but if one side of the ball gap, you should be careful not to let the main axial load through one side of the gap Mizobe. Bearings should pay attention to the side without the ball gap to bear the main load raceway.

 Double row angular contact ball bearings:

Feature:

Double row angular contact ball bearing inner and outer between downtown cumber can be limited, allow Angle depends on the bearing internal clearance, bearing size, internal design and effect on the bearing force and moment, and maximum allowable Angle should guarantee the bearing inner won't produce high additional stress

Types of structural deformation:

Features double row angular contact ball bearings can withstand the combined load of radial and axial loads, limiting the axial displacement of the axis. Compared with the two-way thrust ball bearings, this bearing speed limit is higher, the contact angle is 32 degrees, good rigidity, can withstand the overturning moment, widely used in cars in the front wheels (some models with the same size double row tapered roller bearings).

There are four double row angular contact ball bearing structural deformation:

A type: diameter less than or equal to 90mm bearing standard design. No ball gap, so can withstand the equivalent of a two-way axial load. Light glass fiber reinforced nylon 66 cage, bearing temperature rise is small.

Type A: outside diameter greater than 90mm bearing standard design. Side of the the ball gap with z steel stamping cage or solid brass cage.

E-type: the case of a reinforced structure, the side with filling slots and can hold more ball carrying capacity.

Both sides with a dust cover type and sides with a ring-type design of the A-type and E-type design double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seal (contact). The interior of the sealed bearings are filled with rust-proof lithium grease, operating temperature between -30 degrees to 110 degrees. During use without re-lubrication is no longer heated before installation.

Double row angular contact ball bearings installed should note that the bearings can withstand two-way axial load, but if one side of the ball gap, you should be careful not to let the main axial load through the side of the gap Mizobe.
