Cylindrical Roller Bearings

Double row cylindrical roller bearings with cage can absorb very high radial forces due to the linear contact between rolling element and bearing ring. They are classified into two general designs which differ in flange position on the inner or outer ring. Double row cylindrical roller bearings can be disassembled and are easily installed or uninstalled. They are suitable for medium to high speeds, but they are rigid and cannot compensate angular misalignment

The friction between the rolling element and the ring flange is small, and it rotates quickly. According to whether the ferrule has ribs, it can be divided into NU and NJ. , NUP, N, NF and other single row rolling roller bearings, and NNU, NN and other double row rolling roller bearings. The bearing has a separable structure with inner ring and outer ring.

· Available in various designs

· High to very high load ratings

· Available with cylindrical or tapered bore
