SKF N 311 ECMB/P6 single-row cylindrical roller bearing 55 x 120 x 29 mm

This article is not available

Product description:

  • Cylindrical roller bearings have a high radial load carrying capacity and are capable of rotating at high speeds
  • The rollers are guided by fixed track collars on one of the bearing rings
  • The bearing ring with the track collars and roller set can be slid off from the other ring
  • This makes mounting easier (especially if the bearing is to be mounted both on the shaft and on the bore with a fixed fit)
  • A cylindrical roller bearing can withstand (limited) axial displacement
  • Full complement cylindrical roller bearings: contain as many rollers as possible
  • Double-row cylindrical roller bearing: consist of two rows of cylinders
