Free online tool helps to choose motor bearings

25 September, 2015

The bearing manufacturer Schaeffler has released an online tool that helps users to choose the best rolling bearings for motors and generators, based on mechanical and electromagnetic field loads. The free Bearinx-online Easy EMachine tool can perform calculations for motors and generators in any orientation, and allows users to compare various bearing support options.

Users can specify the weight of the shaft, laminated cores and windings, as well as magnetic tension and other loads. Belt pulleys, gears and shaft imbalances can be modelled at various speeds and under different loads.

The software guides the user through each step of the calculation. Data is shown on-screen for the user to check. The bearings are chosen from a wide variety of variants, and data on INA and FAG rolling bearings can be uploaded from a database. Saved files can be exchanged with Schaeffler’s engineering service or with local technology centres for final checking.

The new tool joins the Bearinx-online family of free online calculators, which includes: Easy BallScrew, for designing ballscrew bearing supports; Easy Friction, for calculating rolling bearing friction; Easy Linear, for monorail guidance systems; Easy Linearsystem, for single- and multi-axis linear systems; and Easy RopeSheave, for the design of sheave bearing supports.
