This 6205-2RS radial ball bearing is made of chrome steel, is double sealed, and has a steel cage. It has a 25 mm inside diameter, a 52 mm outside diameter, and a 15 mm depth. This single-row ball bearing has deep groove geometry for applications that require high speeds and support both radial and axial loads. This bearing's inner and outer races are made of chrome steel for durability and resistance to deformity under heavy loads. It has Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision. Rubber seals on both sides of the bearing keep the lubricant in and contaminants out. A steel cage evenly spaces rollers for reduced friction, vibration, and noise. This ball bearing is for use in various applications such as transmissions, motors, pumps, bicycles, and inline skates, 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.
