Informations:

      Cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.

The cylindrical roller bearing is consisting of the inner ring and outer ring which can be separated. Cylindrical Roller Bearing without sidewall in neither inner nor outer rings can be used as free-end bearings because its inner and outer rings can move relative to the axial. Cylindrical Roller Bearing which has double sidewalls in either inner or outer ring and single sidewall in the other side can bear a certain degree of axial load.

Features:

     1. Roller and groove for line contact or repair referral contact, radial load capacity, is designed to withstand heavy load and impact load.
     2. Small friction coefficient, suitable for high speed, limit rotational speed close to deep groove ball bearing.
     3. N-type and NU type can axial movement and can adapt caused by thermal expansion or installation error and shell the shaft of relative location changes, can make free use of the bearing.
     4. The hole of shaft or block the demand is higher, bearing processing after installation relative skewed to outer ring axis and kept under strict control, lest cause contact stress concentration.
     5. Inner circle or their cups are separable, convenient in installation and removal.

Main application:

     Large and medium-sized motor, locomotives, spindle, internal combustion engines and generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
