Calculator Description
Bearings Calculator (ball & roller) v1
The bearings calculator is used to calculate the life and load ratings of radial and thrust, ball and roller bearings according to Lundberg and Palmgren’s original calculations but with factors corrected to accommodate AFBMA standards

Bearings (roller & ball)

Subject

Ball and roller bearings are commonly known as anti- or low-friction bearings because of their very low start-up torques and negligible rolling resistance.

Due to significant improvements in machining tolerances, material quality and the availability of considerable historic statistical information concerning their use, low-friction bearings are today capable of operating with significantly higher loads without reducing life expectancy. However, plain bearings remain the most appropriate product for applications with exceptionally high operational loads so long as rotational speeds are relatively low.

Calculator

Bearings includes four calculation options:
Radial; Balls & Rollers, and Thrust; Balls & Rollers
the input and output data for each being identical (see below)

Whilst its life and load ratings are calculated according to Lundberg and Palmgren's original theories, Bearings includes factors corrected to accommodate AFBMA standards.

And whilst Bearings also recommends the shaft-fit class, the housing-fit class is dependent upon its design configuration (see Technical Help for assistance with selection).

You may use CalQlata’s Journals calculator to determine the performance of plain bearings and Limits & Fits for further assistance with machining tolerances and shaft-housing fits.

For help using this calculator see Technical Help
