Koyo RCB-162117 Roller Clutch and Bearing, DC Type, Open, Plastic Cage, Inch, 1" ID, 1-5/16" OD, 1-1/16" Width

This Koyo drawn cup roller clutch and bearing assembly with a plastic clutch cage transmits torque between the shaft and housing in one direction and allows free overrun in the opposite direction. It has a roller bearing on each end of the clutch to support radial loads, and a drawn cup outer steel shell that provides a small cross-section for use in restricted spaces. The outer shell serves as a raceway for the clutch and bearing rollers, and the clutch has an acetyl resin polymer cage with integral leaf springs for operation at temperatures up to 200 degrees F (90 degrees C). The rollers are made of through-hardened, high-carbon chromium steel for heat tolerance and durability, and the assembly comes packed with lithium soap grease. This drawn cup roller clutch and bearing assembly is used in various applications, such as athletic equipment, paper towel dispensers, office machines, and appliances, among others.

Roller bearings use rolling elements to maintain a 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. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. 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.
