Product Description

Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row Cylindrical Roller Bearings such as NU, NJ, NUP, N, NF, and double row cylindrical Roller Bearings such as NNU and NN. The bearing is a structure in which the inner ring and the outer ring can be separated.

Cylindrical Roller Bearing features :

1. The roller and raceway are in line contact or repaired line contact, with a large radial bearing capacity, suitable for bearing heavy loads and impact loads.

2. The friction coefficient is small, suitable for high speeds, and the maximum speed is close to that of Deep Groove Ball Bearings.

3. N-type and NU type can move axially and adapt to changes in the relative position between the shaft and the casing caused by thermal expansion or installation errors. They can be used as free end supports.

4. The machining requirements for the shaft or seat hole are high, and the relative deviation of the outer ring axis after bearing installation should be strictly controlled to avoid contact stress concentration.

5. The inner or outer ring can be separated for easy installation and disassembly

Application of cylindrical roller bearings:

Large and medium-sized electric motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transportation Machinery.
