Cylindrical Roller Bearings
Instruction
1. The cylindrical roller bearing is a kind of separable bearing that can be assembled and disassembled conveniently. Owing to the linear contact of a roller and a raceway, its radial load capacity is 1.5 to 3 times as high as that of a deep groove ball bearing of the same size.
2. We have accumulated lots of technology and experience in the design and production of the cylindrical roller bearing. Therefore, we can make different series and sizes of products to meet the needs of different industries.
3. Both ring raceway and roller of the product are machined with a certain range of curvature. This kind of structural style can effectively prevent edge stress concentration. Also, it can improve the friction lubrication condition and service life.
4. The cylinder bearing is mostly applied in high-rigidity operations. For instance, it can be used in the large motor spindle, engine supporting axle, vehicle-axle box, and the tractor gearbox.
Product Classification
1. Single row bearing: NU, NJ, NUP, N, NF, etc
2. Double row bearing: NNU and NN type
3. Free side bearing: NU type, N type, NNU type, and NN type
4. A bearing which bears axial load in one direction: NJ type and NF type
5. Fixed side bearing: NJ,NF and NUP type
Please make the ring side lettering face outwards during the installation of NUP type bearings.
