2 Angular Contact Bearing 7304B 20x52x15 Ball Bearings VXB Brand

The VXB 7304B angular contact ball bearing duplex set is an open bearing and has a 40-degree contact angle, pressed steel cage, and normal clearance rating. The set of two single-row bearings supports moderate to heavy thrust loads, and combined radial and thrust loads. When mounted in pairs back-to-back or face-to-face, the bearing arrangement is relatively rigid for bidirectional thrust loads. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads. The 40-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 lower contact angle. Its open design facilitates lubricating the bearing in place and dissipating heat. 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.Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
