Ball Bearing Axial Load
The contact angle of the bearing is 90 degrees and can only withstand one-way axial load, which may limit the axial displacement of a direction of the shaft or casing, Ball Bearing and the axis of the mounting shaft and the casing hole are not allowed to tilt.
Non-one-way thrust bearings, with stamping housings, the position of the inseparable type of bearings, can withstand one-way axial load, good dust-proof effect. Compared with the one-way thrust ball bearings with the same shape and size, the number of steel balls is more, the axial bearing capacity is higher and the limit speed is lower.
This kind of centripetal thrust ball bearing can withstand the axial load of two directions, which can limit the axial displacement of the shaft or shell in two directions, Ball Bearing and the axis of the casing hole is not allowed to be installed.
The design of double row angular contact ball bearings is basically the same as single row angular contact ball bearings, but only a smaller axial space is occupied. The double row angular contact ball bearing can withstand radial load and the axial load acting in two directions, it can limit the biaxial axial displacement of the shaft or casing, and the contact angle is 30 degrees. It can provide high rigidity bearing configuration and can withstand overturning moment.
(1) The type A is less than or equal to the standard design of 90mm bearings. Ball Bearing No ball gap, so it can withstand the same biaxial axial load. With light glass fiber reinforced nylon 66 cage, bearing temperature rise is very small.
(2) Standard design for B-type outside diameter larger than 90mm bearings. The side has a ball gap, equipped with a steel stamping cage or brass solid cage.
(3) C type is a reinforced structure, side with a ball gap, Ball Bearing can be loaded with more steel balls, so the load-bearing capacity is higher.
(4) Two-row angular contact ball bearings with both sides with dustproof cover and two sides with seal ring type a design and C-type design are available on both sides with a dust-proof cover (non-contact) or a sealing ring (contact type). Sealed bearings inside are filled with anti-rust lithium grease, Ball Bearing operating temperature generally in the -30~+110℃. No lubrication is required during use, should not be heated before installation and should not be cleaned.
Compared with single row angular contact ball bearings, double row angular contact ball bearings have better rigidity and can withstand overturning moment. Ball Bearing The bearing is a non separable type. Especially suitable for applications with high rigidity requirements. Widely used in the car's front wheel hub (some models also use the same size double row tapered roller bearings).
The oblique angle between the inner and outer rings of the two-row angular contact ball bearing is limited, allowing the tilt angles to be determined by the internal clearance of the bearing, Ball Bearing the bearing size, the internal design and the force and torque acting on the bearing, while the maximum allowable tilt angle shall ensure that there is no excessive additional stress in the
If there is a tilt angle between the inner and outer ring of the bearing, the life of the bearing will be affected and the bearing running accuracy is reduced and the running noise is increased. Ball Bearing Double row angular contact ball bearings are generally used in nylon cage or brass solid cage. Double row angular contact ball bearing should be noted, although bearing can withstand biaxial axial load, Ball Bearing but if the side of the ball gap, should be careful not to let the main axial load through the notch side groove. In the use of bearings should be careful to make the side of the ball gap without the main load of the raceway.
