Double Row 40mm ID High strength Angular Contact Ball Bearing 3008-B-Tvh
*Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. Their construction is similar to a pair of single row angular contact ball bearings in an O arrangement but they are narrower to a certain extent. They differ in the size of the contact angle and the design of the bearing rings.
*The bearings are available in open and sealed designs. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Sealed bearings are maintenance-free and therefore allow particularly economical bearing arrangements.
*Double row angular contact ball bearings can support axial forces in both directions and high radial forces. They are particularly suitable for bearing arrangements where rigid axial guidance is required.
*Optimised internal design
*Increased limiting speed
*High strength ball
*High dimensional and running accuracy
*Narrow axial clearances or preloads range
*Universal facing in standard
*Reduced heat generation, vibration and noise
*Easy handling and installation due to universal facing
*high speed ccnpacity
5) Application: home appliances, low noise and high speed electric motors; automotive components, pumps, machinery.
Feature of Angular contact ball bearings:
When the single-row angular contact ball bearing is carrying the radial load, they will be a component of force in the axial direction. Therefore it is suggested that two of there bearings be applied in back-to-back or face-to-face arrangements. Single row bearings can carry radial load and axial load in one direction. Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining.
These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.
