6308-2NSE Nachi Bearing 40x90x23 Sealed C3 Japan Ball Bearings

This Nachi 6308-2NSE ball bearing is made of chrome bearing steel and has rubber seals. It has a 40 mm inside diameter, a 90 mm outside diameter, and a 23 mm depth The bearing has deep groove geometry for supporting both radial and axial loads and high speeds. The races are made of chrome bearing steel for durability and resistance to deformity under heavy loads. The C3 radial clearance allows thermal expansion for continuous operating temperatures up to 248 degrees F/120 degrees C. Rubber seals on both sides of the bearing help retain lubricant and exclude contaminants. The ball is made of chrome bearing steel for strength and resistance to wear and deformation. The static load rating is 24,100 newtons and the dynamic load rating is 40,500 newtons. A steel cage spaces the balls for even load distribution and prevents contact to reduce friction, vibration, and noise. The maximum speed with grease lubrication is 5,300 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as electric motors, compressors, and material handling equipment, 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.
