rubber cover for bearing NTN cylindrical roller bearing NU311

Description of Cylindrical Roller Bearings:

Cylindrical roller bearings are available in many designs, series and sizes, including single row bearrings with a cage, High-capacity bearing, single and double row full complement bearings (without a cage).

Cylindrical Roller Bearings with a cage can accommodate heavy radial loads, fast accelerations and high speeds. Full complement bearings incorporated a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.

Feature of Cylinrical Roller Bearings:

cylindrical roller line contact with the raceway, radial load capacity, both for load and impact load to bear weight, but also for high-speed rotation.

 Cylindrical roller bearingraceway and rolling element geometry improved after the design has a high carrying capacity, rib and roller end of the new structural design not only improves the axial load bearing capacity, while improving the roller face contact area with the wall lubrication conditions, and improve the bearing performance.

Types:

1.)single row cylindrical roller bearings, caged ,mainly of the NU,NJ NUP and N designs
2.)double row cylindrical roller bearings ,caged,mainly of the NNU and NN designs
3.)multi-row cylindrical roller bearings, caged
4.)single row full complement cylindrical roller bearings ,mainly of the NCF and NJG designs
5.)double row full complement cylindrical roller bearing bearings,mainly of the NNF design
6.)multi-row full complement cylindrical roller bearings, with four or eight rows of rollers
