Key Features

  • NSK 200 series cylindrical roller bearing with machined brass cage and removable outer ring suitable for high radial loads
  • CN (normal) radial clearance for applications where thermal expansion is not a factor
  • Single row roller bearing for high radial loads with low friction
  • Removable outer ring in open bearing allows for lubrication in place
  • Brass cage evenly spaces rollers for reduced friction, vibration, and noise

Product Description

This NSK 200 series cylindrical roller bearing with a machined brass cage and removable outer ring is suitable for applications that support high radial loads. This roller bearing has a CN (normal) radial clearance for applications and operating conditions with normal shaft and housing tolerances where thermal expansion is not a factor. This is a single row roller bearing that supports high radial loads with low friction. A removable outer ring in the open bearing allows application of lubrication. The brass cage prevents the rollers from coming into contact with each other during use, reducing friction, vibration, and noise.

Cylindrical roller bearings are used in applications where high radial loads are present such as in conveyer belts, traction motors, railway car axle boxes, and oilfield mud pumps, among others.

Roller or rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. They are usually composed of two rings, rolling bodies (such as bearings or cylinders), and a cage to house the parts. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Rolling bearings can be 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.

NSK manufactures ball and roller bearings, linear guides, and other components for automotive and industrial applications. The company, founded in 1916, is headquartered in Tokyo, Japan with offices in Ann Arbor, MI.
