Ball Bearing Tilt Is Limited
Double row angular contact ball bearings are basically designed to be the same as single row angular contact ball bearings, but only occupy smaller axial spaces. Ball Bearing Double row angular contact ball bearings can withstand radial loads and axial loads acting in both directions, which limits axial displacement of the shaft or housing, with a contact angle of 30 degrees. Can provide a higher rigidity of the bearing configuration, Ball Bearing and can withstand overturning moment.
Double row angular contact ball bearings can withstand a large radial load-based radial and axial joint load and torque load, limiting the axial axial displacement of both sides. Mainly used to limit the axial displacement of the shaft and the shell in the component.
(1) A type of outer diameter less than or equal to 90mm bearing the standard design. Ball Bearing No ball gap, so can withstand the same two-way axial load. The use of light glass fiber reinforced nylon 66 cage, bearing temperature rise is very small.
(2) B-type diameter greater than 90mm bearing the standard design. Ball Bearing One side has a ball gap, equipped with steel stamping cage or brass solid cage.
(3) C-type reinforced structure, one side with a ball gap, you can install more steel ball, so the higher carrying capacity.
(4) Both sides with dust cover and both sides with a ring-type A-type design and C-type design of double row angular contact ball bearings can be both sides with dust cover (non-contact) or seal (contact ). Ball Bearing Sealed bearings are filled with rust-proof lithium-based grease, the operating temperature is generally in -30 ~ +110 ℃. Do not need to lubricate during use, should not be heated before installation, Ball Bearing should not be cleaned.
Compared with single row angular contact ball bearings, double row angular contact ball bearings with better rigidity, can withstand overturning moment. The bearing is non-separate.Ball Bearing Especially for applications with high rigidity requirements. Widely used in the front wheel hub of the car (some models also use the same size double row tapered roller bearings).
The angle between the inner and outer rings of the double row angular contact ball bearings is limited, and the allowable inclination angle depends on the internal clearance of the bearing, Ball Bearing the bearing size, the internal design and the forces and moments acting on the bearing, and the maximum allowable inclination angle The bearing will not produce too high additional stress.
If the bearing, the outer ring between the tilt angle, Ball Bearing will affect the bearing life, while causing the bearing running accuracy, operating noise increases. Double row angular contact ball bearings generally use nylon cage or brass solid cage. Double row angular contact ball bearings should be noted that although the bearing can withstand two-way axial load, but if there is a ball on the side of the gap, Ball Bearing it should be careful not to let the main axial load through the gap side of the groove. Care should be taken when bearing is used to bear the main load on the side of the raceway without the ball.
