Nachi Radial Ball Bearing 6203, Open, 17mm Bore, 40mm Od

This Nachi 6203ZZE C3 ball bearing is made of chrome bearing steel and has metal shields. It has a 17 mm inside diameter, a 40 mm outside diameter and a 12 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. Metal shields 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 4,800 newtons and the dynamic load rating is 9,550 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 18,000 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as electric motors, compressors, and material handling equipment, among others.
