Determination of Optimum Preload Considering the Skidding and Thermal Characteristic of High-Speed Angular Contact Ball Bearing …

9/3/2018· Skidding is a typical behavior of high-speed angular contact ball bearings. Studies show that the effect of preload on bearing skidding and thermal characteristic is essential but insufficient. This paper proposed a comprehensive mathematic model to predict the skidding behavior of ball bearing, and the influences of the interactions between ball and raceways, …

12. Preload | Engineering Information | MinebeaMitsumi Product …

If the preload is the dominant load applied to the bearing, MinebeaMitsumi recommends an optimum preload based on the "surface stress" calculation, which focuses on noise life. When the preload (F a) is applied to the ball bearing, a small contact ellipse is generated as a result of elastic deformation of the contact areas between balls and raceways.

Bearings - Centrifugal Pumps - Beyond Discovery

The double-row, angular contact ball bearing (see Figure 93) is similar in design to a back-to-back pair of single-row, angular contact ball bearings, but in a narrower width package. Its ease of mounting, along with its low-friction operation, high-speed capability, and seal or shield availability, make it an ideal bearing for light- to medium-duty end suction centrifugal pumps …

FAQ - Enduro Bearings

Enduro Bearings Angular Contact (A/C) bearings require some preload, though not nearly as much as the the XD-15 Corsa A/C bearings. This is because they have a shallower A/C design. The bottom bracket torque nuers for A/C bearings should be 12-26 inch lbs, or 1.2 – 3 Nm. This is roughly twice the normal radial bearing torque nuers.
