All-metal rolling bearings made from higher grade bearing steels or alloys are advantageous for many applications, particularly with severe operating conditions. Nitrided all-steel bearing rings provide high surface hardness and deep compressive residual stress. This leads to better rolling contact fatigue resistance than with standard bearing steel. Nitrided all-steel bearings are widely used in Turbo Systems in aircraft and industry applications to meet the following requirements:
1. Design development demands reduced weight, increased load capacity and broadened operating range:
- higher service temperature
- higher working speed
- thinner section
- integral design (flange, squirrel cage, integral gears with racings)
2. For Safety Components
- increased fatigue life (contact, and structural fatigue)
- higher level of reliability
3. Reduction of manufacturing and maintenance costs
- reduced cost by Precision Hard Turning over grinding
- improved tolerance to lubricant pollution
Top features of our all-metal bearings meeting the required needs of the industry:
- Advanced materials, such as BG42®, M50, M50 NiL®, M50 NiL® nitride, Inconel 718, Tribaloy T800
- Enhanced rolling contact fatigue resistance allows down-sizing or bearing life improvement
- Extreme temperature- and corrosive environment capability
- Cost reduction by lower rejection rate (M50 NiL nitrided), much less distortion than with carburized rings, which allows parts design with integral functions (geared bearing rings, squirrel cages, flanges, splines, threads etc.)
