This SKF 6203-2Z deep groove ball bearing is made of stainless steel, is double shielded, and has CN internal clearance. It has a 17 mm inside diameter, a 40 mm outside diameter, and a 12 mm depth. This single-row ball bearing has deep groove geometry for applications that require high speeds and support both radial and axial loads. This bearing's inner and outer races are made of stainless steel for durability and resistance to deformity under heavy loads. It has Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision. This ball bearing conforms to ABEC 1 precision standard for performance within a narrow range of variation. Metal shields on both sides of the bearing keep the lubricant in and contaminants out. This bearing has case-hardened bearing quality steel ball bearings for optimum wear resistance. Its "Light" bearing design makes it suitable for use in limited space applications or for average loads. The stainless steel cage evenly spaces rollers for reduced friction, vibration, and noise. This bearing is suitable for rotation up to 28,000 RPM. This deep groove ball bearing is for use in various applications such as transmissions, motors, and pumps, 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.
