Spherical Roller Bearings
Spherical roller bearings are double row, angularly adjustable bearings which can compensate angular misalignments due to the spherical outline of the outer ring raceway and the barrel-shaped rolling elements. They absorb very high radial as well as axial forces, but they are not suitable for high speed needs. Spherical roller bearings cannot be disassembled and are suitable for use with heavy shaft deflections and angular misalignments between bearing positions.
Compensation of angular misalignments
Absorption of high radial and axial forces from both directions
Suitable for medium speeds
Dimensions and Tolerances
The boundary dimensions of the bearings are standardised in ISO 15, DIN 616 and DIN 635-2. 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.
