Cylindrical roller Slewing bearing(cylindrical roller bearing)
    Rolling element is a cylindrical roller bearing to the heart.
Cylindrical roller bearings
    Cylindrical roller and raceway contact bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. According to ring without ribs can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing is the inner, outer separable structure. Inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free-end bearings. In the inner and outer side of a double wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy machined cage. But there is a polyamide forming cage.
Cylindrical roller bearings Features:
    1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
    2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings.
    3. N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of the shaft and the housing due to changes in relative position, can be used for supporting the free end.
    4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.
    5 inner or outer ring detachable, easy installation and removal.
Main purpose:
    Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting and transport machinery.
