6005 Nachi Bearing Open C3 Japan 25x47x12 Ball Bearings

This Nachi single-row deep groove ball bearing is unsealed and has C3 clearance. It has high-carbon chrome steel races and bearing balls for increased wear and fatigue resistance. The bearing is open on both sides for lubricating the bearing in place and has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has C3 radial internal clearance for applications where radial slack between the inner and outer rings is greater than CN (normal) to compensate for thermal expansion. This ball bearing is suitable for use in automotive and industrial machine applications such as material handling equipment, electric generators, and machine tools. 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.
