The 6203-2Z is a 17mm single row radial ball bearing that’s sealed with metal on both sides and pre-lubricated with grease. It’s a 40mm OD sealed ball bearing 6203-ZZ made of chrome steel and features deep groove geometry that’s perfect for high speeds and heavy radial and axial loads. Rolling bearings like 6203-2ZR 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 6203-ZZ bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan.

6203ZZ bearing is 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, motorcycles, household appliances, power tools and machines, gear boxes, and among others.
