Taper Roller Bearings
NSK Taper Roller Bearings can support high radial loads and axial loads in a single direction. Also available in two and four row versions which are capable of taking axial loads in either direction. These bearings can be supplied with high strength cages (optimised designs) and in a range of advanced special materials for arduous applications.
Product Features:
- Material Technology - Hardened high carbon chromium steel
- Advanced Materials - Patented materials including High TF and Super TF are available for more arduous conditions
- Patented NSK HR taper roller bearings with higher load rating
- NSK cage optimised for large taper roller bearings installed in planetary carriers
- Segmented plastic cage for inner diameters of more than 1000 mm
- Metric and imperial dimensions
- Outer diameters up to 2500 mm
Product Benefits:
- High radial and axial loads in one direction
- Axial loads in both directions when arranged in pairs
- Medium speeds
- Small clearance range when bearing pairs are adjusted during mounting
- Higher permissible speeds by improved raceway surface roughness
High accuracy pressed steel cage controls roller position resulting in low heat generation and reduced wear properties
NSK range of Taper Roller Bearings include: single row taper roller bearings, double row taper roller bearings, four row taper roller bearings, Molded-OilTM bearings, etc.
