Cylindrical Roller Bearings
double row, with cage
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.
Available in various designs
Very high load ratings
Available with cylindrical or tapered bore
Dimensions and Tolerances
The boundary dimensions of the bearings are standardised in ISO 15, DIN 616, and DIN 5412-1. ALPHA Wälzlager GmbH supplies double row cylindrical roller bearings with normal tolerance (PN) in accordance to DIN 620-2 and ISO 492. Please contact our technical department to check the availability of bearings with improved accuracy class or special tolerances.
Radial Internal Clearance
ALPHA double row cylindrical roller bearings are supplied in normal clearance (CN) in accordance with DIN 620-4 and ISO 5753-1, but they are also available in all clearance classes with restricted clearance or increased clearance.
