Product Description
Cylindrical Roller Bearings
double row, with cage
- Available in various designs
- High to very high load ratings
- Available with cylindrical or tapered bore
- 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 misalignments.
