We produce this type of bearing with SKF technology, it can be used for mine & coal industry. Stock order like 1-4PCS can be acceptable.

Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load. Roller and ring guard friction small, suitable for high speed rotation. May according to the ring presence of guard, NU, NJ, NUP, N, NF, such as single row cylindrical roller bearings, double row cylindrical roller bearing and NNU, NN and other. The bearing inner ring and outer ring is separable structure. No guard of cylindrical roller bearing inner ring or outer ring, internal ring and outer ring can be to relative axial movement, so can be used as free end bearing. The one side of the inner ring and outer ring with double guard, on the other side of the ring has a single guard cylindrical roller bearing, can withstand a certain degree of axial load in one direction. General use of stamping steel cage, cage or copper alloy car system entities. But there are also part of the use of polyamide forming keep frame.

Cylindrical roller bearings feature
1. The roller and raceway for the line contact or offline contact, radial bearing capacity big, apply to under heavy load and impact load.
2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.
3. The N type and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.
4. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration. 5. The inner ring or outer ring separable, easy to install and disassemble.

Bearings USES
Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
