17x47x19 Bearing

This NFS17 one-way backstop clutch is intended for use with an adjacent 6202 series supporting roller bearing to support radial and axial loads. The bearing has a 17 mm inside diameter, a 47 mm outside diameter, and a 19 mm depth. The clutch mechanism is made of chrome steel for durability and resistance to deformity under heavy loads. Side notches in the outer race and a keyed inner race provide positive torque transmission. Seals on both sides of the clutch mechanism keep the lubricant in and contaminants out. This sprag clutch bearing rotates in only one direction to provide overrunning, indexing, or backstop functionality for applications requiring stoppage of rotation without rollback, such as in washing machines and conveyor systems.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction 17x47x19 Bearing 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 NSK 6006du Bearing machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
