NTN Americas | Industrial Cylindrical Roller Bearings

Offer cylindrical roller bearings under the NTN and Bower® brand names, we use premium steels and special heat treatments to extend life and increase reliability when appliions require. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance.

Lubriion and Fatigue Life Evaluation of High-Speed Cylindrical Roller Bearing under Misalignment

5/10/2020· This paper developed a coupled model, incorporating the quasistatic model, fatigue life model, and mixed lubriion model, to investigate the effect of misalignment angle on high-speed cylindrical roller bearings. The model is verified by comparing with the published literature results. Then, a parametric analysis is carried out.

Electric Motor Bearings - HECO All Systems Go

These bearings don’t require a cage and race in the same way that ball bearings do. Electric motor roller bearings are used for belted appliions with motors 150 HP and above. The surface of the cylindrical shape rolling elements helps to account for the high level of radial load that the belts put onto the bearings.

» The SKF formula for rolling bearing life

16/2/2001· SKF life formula. A simple analytical formulation for bearing life that includes consideration of the fatigue strength of the material evolved from the rolling contact fatigue model set forth by Ioannides and Harris (1985). This was initially applied in the numerical solutions of the fatigue risk of 3-D stress fields of rolling contacts.
