About SKF 6304 2ZJEM Medium Series Deep Groove Ball
The SKF Medium series deep groove ball bearing is a double-shielded non-contact ball bearing with Annular Bearing Engineering Committee (ABEC) 1 precision and C3 clearance and has a deep-groove geometry for high speeds and supporting both radial and axial loads. It has a medium bearing structure for average to above average radial loads and light to average axial loads. This bearing conforms to the precision standard ABEC 1 for performance within a narrow range of variation and 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 steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. Non-contact shields fasten to the outer ring on both sides of the bearing to keep lubricant in and contaminants out. This Medium series deep groove ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy and stiffness at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile 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
