Cylindrical Roller Bearings
multirow, with cage
Multi row cylindrical roller bearings with cage can absorb extremely high radial forces due to the linear contact between rolling element and bearing ring and the high number of rolling elements. They are classified into two general designs which differ in separation of the inner ring. Multi row cylindrical roller bearings can be disassembled and are easily installed or uninstalled. They are suitable for high speeds, but they cannot compensate angular misalignments.
Precise shaft guidance with high rigidity
Very high load ratings
Inner and outer rings with roller cage assembly available separately
Dimensions and Tolerances
The boundary dimensions of the bearings are not standardized. ALPHA Wälzlager GmbH supplies multirow 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 multirow 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.
