double row cylindrical roller bearing

cylindrical roller bearing and the raceway is in line contact bearings. Load capacity, the main radial load. Rolling ring wall friction small, suitable for high-speed rotation. According to ring without ribs, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearing. The bearing is the inner, outer separable structure.

thrust roller bearing

roller bearing appear before spherical shape. With this roller bearings with self-aligning properties, can withstand great load. Spherical roller sub asymmetric and symmetric shape, large end generally asymmetric spherical, symmetrical surface is flat end faces at both ends. Symmetrical spherical roller child better performance, rather than the symmetrical form is eliminated. Such roller for spherical thrust roller bearing and spherical roller bearings.

single row cylindrical roller bearing

No inner or outer wall of the cylindrical roller bearing, the inner and outer ring can be relative to the axial movement, so it can be used as a free end bearings. On either side of the inner and outer double wall, rings the other side of a single row cylindrical roller bearing, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also part of the use of polyamide forming cage.

Roller bearing function

As can be seen for different reasons in different frequency corresponding to the frequency of failure tapered bearing supplier because only a small mounting structure caused when the spherical roller bearing element has manufacturing defects or serious damage to severe vibration frequency will be significantly improved .the pulse energy from the impact analysis,When the spherical roller bearing elements have tiny little damage pulse value fault with the development of the pulse value increases vibration intensity also increased split roller bearing significantly.

high precision slewing bearings

Through 50 years of construction and development of China's bearing industry has achieved a small to a great weak to strong development strategy formed the production layout is reasonable, medium high precision slewing bearings and small enterprises co-exist, relatively complete product of relatively complete industrial system. And with a larger production capacity and strong technical strength.
At present, China 's bearing industry has had a larger economic scale enterprises in the country bearing more tapered roller bearings than 1,400 employees in about 30 million people.
