Single Row , Cylindrical Roller Bearing With 670mm Bore NU 20 / 670 ECMA

Feature:

    Cylindrical rollers have linear contact with the raceway, and the bearings can carry heavier radial load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed. The N type and NU type bearings can be movable along the shaft. liner bearing, line bearing, linear bearing, They can adapt to the position changes between the shaft and housing caused by the thermal expansion or the mounting error and are most suitable for free end shafts. NJ and NF types can accept certain axial load in one direction, and NH and NUP types can accept certain axial load in two directions. Inner ring and outer ring can be separable, and be they are convenient to mount and dismount. FC, FCD and FCDP types can carry comparatively heavy radial load and are mainly applied for mill rolls. liner bearings, line bearings, linear bearings, steel mill bearing, cylindrical roller bearing, heavy load bearing, double row bearing, single row cylindrical roller bering, double row cylindrical roller bearing, four row cylindrical roller bering, Large Cylindrical roller bearings, Large diameter cylindrical roller bearings, Custom Cylindrical roller bearings, Large size cylindrical roller bearings.

  

Applications:

    These bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, unloading and lifting machines and other industrial machines.
