This 6203Z 17x40x12-millimeter single-shielded ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. It is sealed on the side of the bearing exposed to contaminants and open on the other side for applying lubricant, and it comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove shielded ball bearing is suitable for use in electric motor applications.

- 10 6203Z 17x40x12-millimeter ball bearings
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.
