Cylindrical roller and roller way for line contact bearing. Load capacity, mainly bear radial load. Rolling body and ring guard friction small, suitable for high speed rotation. According to the ring for guard, can divide a NU, NJ, NUP, N, NF and single row bearing, and NNU, NN and double bearing. The bearing is inner ring and outer separable structure. Inner ring or no outer rim of cylindrical roller bearing, its outer circle and to axial relative movement, so can be used as free end bearing use.In outer circle and one side of two guard, the other side of the ring with a single guard of cylindrical roller bearing, may have a certain degree of one direction axial load. General use steel plate stamping cage, or copper alloy car system cage. But there are also part of the use of polyamide forming cage.
Cylindrical roller bearing features: 1. The roller and roller way for line contact or repair referrals contact, radial bearing capacity is big, is designed to withstand heavy loads and shock load. 2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearing. 3. N type and NU type can be axial movement, can adapt for thermal expansion or installation error caused by the shaft and housing relative position change, can make free end bearing use. 4. To shaft or seat hole processing the demand is higher, after installation bearing outer axis relative deviation to kept under strict control, so as to avoid the contact stress concentration. 5. Inner ring or their cups are separable for easy to install and remove.
Main application: large and medium-sized motor, engine vehicle, machine tool spindle, internal combustion engine, generator, gas turbine, reducer, rolling mill, vibrating screen and lifting the transport machinery, etc.
