Product description：

The angular contact ball bearing is double-sealed and has a 20-degree contact angle, pressed steel cage, and normal clearance rating. It supports radial loads, thrust loads in both directions, and combined loads, and occupies less thrust space than a pair of single-row angular contact ball bearings mounted together. Because the two rows of rolling elements are mounted back-to-back, the bearing arrangement is relatively rigid and can accommodate tilting moments. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads. The 20-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a standard contact angle of zero degrees. Rubber seals on both sides of the bearing keep out contaminants such as dirt and grime and hold in lubricant applied at manufacture. This bearing has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has a normal axial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. This angular contact ball bearing is for use in commercial and industrial applications including pumps and compressors, automotive drives, gearboxes, and printing machines, among others.

The Application: 

Mixed color machine, corrugated pipe equipment, plastic packaging equipment, sterilization machine, filling machine, filling machine, sealing machine, multi-function packaging machine, heat shrink packaging machine, printer, and other equipment.
