C3 CLEARANCE SPECS DATA
6307-2ZC3 This single-row radial bearing 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 6307-ZZC3 it has two press metal seals on outer ring to protect bearing from any alien objects and corrosion of internal components and they are non-contacts toward inner ring, it also has metal retainer, the retainer also referred to as the cage or separator, is used to separate and position the balls at equal intervals around the bearing raceways. The 6307ZZCM is precision ABEC1 or P0 international standard accuracy, 6307.2ZR.C3 is capable of carrying axial load and rotation at the same time as light duty ball bearing.
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.
