This 608-2RS miniature radial ball bearing has black double seals and a nylon cage, and conforms to the ABEC 9 precision standard. This light duty bearing has an 8 mm bore diameter, a 22 mm outside diameter, and a 7 mm width. This bearing is made of ASTM International 52100 steel and heat treated to increase hardness for optimum wear resistance. Its deep ball grooves in both races support high radial and axial loads, its straight bore fits conventional cylindrical shafts, and its nylon cage prevents the balls from coming into contact with each other during use, reducing friction, vibration, and noise. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. All rolling bearings are open, shielded, or sealed. 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. High quality skate bearing, work with all types of skateboards, longboard, inline skating and other skating applications.
