42-1006 3203 Double Row Angle Touching Bearings / Made in China / 3203 ZZ / 3203 2RS
Double row angle Touching bearings Profile
Double row angle Touching bearings can withstand greater radial load mainly radial and axial joint load and torque load limit both the axial displacement of the shaft.The main components used to limit the bi-axial displacement of the shaft and housing.
Such as: contact ball bearings SKF double row angular contact ball bearings, single-row design with two back-to-back arrangement is similar to, but slightly narrower width than two single row bearings. Better rigidity than single row bearings.
Double row angle Touching bearings Structural variants
(1) A type of an external diameter less than or equal to 90mm bearing of standard design. No filling slots, it can withstand the equivalent two-way axial load. Lightweight glass fiber reinforced nylon 66 cage, bearing temperature rise is very small.
(2) Type A diameter greater than 90mm bearing the standard design. Filling slots on one side, with steel stamping cage or solid brass cage.
(3) E is a reinforced structure on one side with filling slots that can hold more steel balls, and therefore a higher carrying capacity.
(4) Both sides with a dust cover and sides with a ring-type A-type design and E-type design double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seals (contactless). Inside the sealed bearings are filled with anti-rust lithium grease, operating temperature of -30 to +110 ° C. Without further lubrication during use, should not be heated prior to installation, nor should be cleaned.
Double row angle Touching bearings Feature
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, bearing size, bearing on the internal design and the role of force and torque, while the maximum allowable tilt angle should guaranteethe bearings will not generate excessive additional stress.
If the bearing inner and outer tilt angle between, will affect the life of the bearings, also causing the bearings running accuracy decreased, increased running noise. Double row angular contact ball bearings generally use the the nylon cage or solid brass cage. Double row angular contact ball bearing installation should pay attention bearings can withstand two-way axial load, but if the side filling slots, you should be careful not to let the main axial load through a gap in the side of the gutter. Note bearings should be used to bear the main load without filling slots on one side of the raceway.
Double row angle Touching bearings Application
Compared with the single-row angular contact ball bearings, double row angular contact ball bearings have better rigidity, can withstand the overturning moment. Bearing non-separated. Particularly suitable for applications where high rigidity requirements. Some models also widely used in the front wheel of the car (the same size of a double-row tapered roller bearings).
