Product Description

Cylindrical roller bearing


Cylindrical roller and groove for line contact bearings. Load capacity, which mainly bear radial load. With roller ring, suitable for high speed raised edge friction small rotation. According to have raised edge, can divide front-runners NU, floatation, NUP there, N, NF, etc, and NNU, single bearing such double row bearings NN by. This bearing is inner circle and outer separable structure. Inner circle or outside the cylindrical roller bearing no raised edge inside circle and outer, relative to axial movement, so it can be used as a free end bearing. The outer circle and, a side have double raised edge, another side of the collar with a single raised edge, cylindrical roller bearing can afford to a certain degree of axial load in one direction. Use commonly stamping steel cage, or copper alloy system maintains a car. But there are also part of the use of polyamide forming keep frame.


Cylindrical roller bearing 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.


Structural form:


1. No N0000 type and outer circle of inner raised edge without NU0000 raised edge type cylindrical roller bearing these bearings can accept the big radial direction load, extreme high speed, not bound shaft or shell axial displacement, cannot accept the axial load.


2. Both inner and outer raised edge of cylindrical roller bearing with NJ0000 type, NF0000 type bearings can be bound shaft or shell the axial displacement in one direction, and can accept smaller one-way axial load. NU0000 + HJ0000 type, NJ0000 + HJ0000 type, NUP0000 type bearings, can be in import bearing axial clearance field bound axis or shell the axial displacement of two directions. And can accept smaller two-way axial load.


Cylindrical roller bearing category


Cylindrical roller bearing: single


Single cylindrical roller bearing is separable bearing, easy to install and disassemble, two front-runners can adopt a tight fit, modified roller and groove can reduce the contact line between stress concentration.


Double row cylindrical roller bearing:


Double row cylindrical roller bearing belongs to the winding bearings to separability erection and dismantling of very convenient. Two rings should be adopted a tight fit.


Double row cylindrical roller bearing nearly are not allowed to have occurred
