6204-2RS Hybrid Ceramic Sealed Bearing 20x47x14 Ball Bearings

This 6204-2RS 20x47x14-millimeter hybrid sealed ceramic ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. Its chrome steel construction makes it durable and resistant to deformity under heavy loads and it has C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion. The rubber seals on both sides of the bearing keep lubricant in and contaminants out. The zirconium oxide ceramic bearing balls provide low friction, high hardness, density, and shock tolerance, and resistance to chemicals, heat, and fracturing, and the chrome steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. This deep-groove sealed ball bearing is suitable for use in electric motor applications.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.
