INA Cylindrical roller bearings


INA Cylindrical roller bearings
Cylindrical roller and raceway for the line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, can be divided NU, NJ, NUP, N, NF and other single row bearings, and

NNU, NN and other double row bearings. The bearing is the inner, outer separable structure. Inner or outer wall of the cylindrical roller bearings, the inner and outer ring can be relative to the axial movement, so you can use as a free end bearings. In the inner and outer

One side of the ring of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings that can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy machined cage. But there are also a part of poly

Amide forming cage.
Cylindrical roller bearings are suitable for medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting and transport machinery. Product Features
Cylindrical roller line contact with the raceway, radial load capacity, both for heavy load and impact load, but also for high-speed rotation.
Cylindrical roller bearing raceways and rolling back the geometry of the improved design, with a high carrying capacity, ribs and roller end of the new design, not only improves the axial bearing capacity, while improving the roller end the contact area with the wall

Domain lubrication conditions, improve the performance of the bearing.
Such bearings are mainly used for medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling machinery, industrial machinery.
