SKF Bearings for Power Transmission

Gearboxes, reducers and other drive units rely on bearings to support gear and output shafts under combined radial and axial loads. Shock loads, oil contamination and tight mounting tolerances make the choice of bearing arrangement critical during a repair. Buyers focus on the exact designation for each shaft position so the rebuilt unit keeps its original setting.

• Replace bearings by shaft position, since input, intermediate and output shafts often carry different loads and bearing types.
• Use tapered roller bearings where combined radial and axial loads need a set preload or end play on assembly.
• Use cylindrical roller bearings for high radial load positions and check the ring configuration against any axial location requirement.
• Check cage material and clearance suffixes against oil type and operating temperature before approving any alternative.
