NoWear Coated Bearings
NoWear Coated Bearings
NoWear is a wear-resistant carbon coating that can be applied to the rolling elements and inner ring raceway(s) of a bearing (designation suffix L7DA) or only the rolling elements (designation suffix L5DA).
A physical vapour deposition process applies the wear-resistant carbon coating. Thickness of the coating ranges from 1 to 3 μm, depending on the size of the bearing. The hardness of the coating is 1 200 HV10.
NoWear coated bearing surfaces retain the toughness of the underlying material while adopting the hardness, improved friction properties and wear-resistance of the coating.
During the running-in period, minute amounts of the coating material are transferred to the counter-surfaces. This coating reduces friction and improves resistance against wear and smearing, even in bearings where only the rolling elements are coated
Explorer deep groove ball bearings – meeting demands beyond standard
More robust than typical deep groove ball bearings, they are highly customizable with the possible combination of many different components. This results in up to 10 000 possible configurations! Find the optimum configuration to deliver the kind of high performance you need – whether that’s exceptional durability, for example, or lower friction.
Quiet Running deep groove ball bearings
Designed especially for wind turbine generators, SKF Quiet Running deep groove ball bearings significantly reduce noise levels and structural resonance. They are less sensitive to variable operating conditions, can increase bearing service life and extend relubrication intervals.
Applications
NoWear coated bearings may provide new possibilities for existing applications operating under severe conditions. They can provide new design possibilities while requiring no major design changes. Typical applications where NoWear coated bearings are used include:
- Railways
- paper machines
- marine
- offshore applications
- fans
- compressors
- hydraulic pumps
- gearboxes
- hydraulic motors
NoWear coated bearings are not intended for vacuum or other completely dry running applications. The coating does not act as a barrier against oxygen, and is therefore not recommended as a corrosion inhibitor.
