Roller Bearing Can Be Used As A Free End Bearing
- Oct 17, 2017 -

Roller bearings according to the ring with or without ribs, points NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN double row bearings. The bearing is the inner ring, the outer ring can be separated from the structure. Inner or outer ring without ribs cylindrical roller bearings, the inner ring and outer ring can be relative to the axial movement, it can be used as a free end bearing.

What are the characteristics and uses of roller bearings?

1: roller and raceway for line contact or repair off contact, radial load capacity, suitable for those who bear heavy load and impact load.

2: the friction coefficient is small, suitable for those high-speed, limit speed close to deep groove ball bearings.

3: N type and NU type can be axially movable, can adapt to those due to thermal expansion or installation error caused by the relative position of the shaft and the shell changes can be used for free end support.

4: the shaft or seat hole processing requirements are higher, the bearing after the installation of the outer axis of the relative deflection to be strictly controlled, so as to avoid contact stress concentration.

5: inner or outer ring can be separated to facilitate the installation and removal of bearings.

The main purposes are: large and medium-sized motors, locomotives and rolling stock, machine tool spindle, internal combustion engine, generator, gas turbine, gear box, rolling mill, vibrating screen and lifting transport machinery.

Roller bearings and roller bearings are all rolling bearings, the simplest is a rolling body is a ball, that is, steel ball. The other rolling body is steel.
