Product Description: Cylindrical roller bearings


Cylindrical roller in line contact with the roller 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. No 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 the free end of the bearing. In the inner and outer rings on one 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 are also part of the use of polyamide forming cage.   Cylindrical roller bearings feature:  1. roller and raceway contact or repair off the assembly line for the line contact, the radial load capacity, suitable to withstand heavy load and shock load.  2. friction coefficient is small, suitable for high-speed, speed close to the deep groove ball bearings.  3. N type and NU type can move axially, can adapt to errors due to thermal expansion or installation of the shaft and housing caused by changes in relative position can be used for supporting the free end.  4. on the shaft or housing bore machining are higher, and bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.  5. detachable inner or outer ring for easy installation and removal.  Main purposes: Medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting and transportation machinery.  Type of construction:  1. The outer ring without ribs N0000 NU0000 type and no inner wall of this type of cylindrical roller bearings radial bearings accept larger load, high speed limit, not bound axial displacement of shaft or housing, can not accept axial load .  2. Inner and outer rings with the ribs are cylindrical roller bearings NJ0000 type, NF0000 bearing shaft or housing can be bound axial displacement in one direction, and can accept a smaller one-way axial load. NU0000 + HJ0000 type, NJ0000 + HJ0000 type, NUP0000 bearings, axial bearings may be gaps in the areas of housing restraint axis or axial displacement in both directions. And accept a smaller two-way axial load.
