5204-2RS Precision Double Row Angular Contact Ball Bearing
5204-2RS has a 20-degree contact angle, pressed steel cage, and normal clearance rating. 5204-2RS 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 5204-2RS bearing arrangement is relatively rigid and can accommodate tilting moments. The 5200 series has a smaller cross section than the 5300 series, making it suitable for smaller spaces, lighter loads, and higher speeds. This 5204-2RS 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 0 degrees. 2RS or 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 5204-2RS has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The 5204-2RS 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 5204-2RS 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 and Shielded bearings are lubricated with oil or grease in the bearing factory, while open 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, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
