Maximum load on

Maximum load on

Maximum load on

(OP)
Does anyone know a simple calculation to calulate maximum raidal load on an over-hung shaft (i.e - dc motor) supported by 2 ball bearings spaced?

Cheers,

RE: Maximum load on

Contact your bearing manufacturer's application department.

RE: Maximum load on

The radial load on the front bearing is almost the same as the overhung radial load.  Motor manufacturers usually state the load rating based on (usually) a 10,000 hour running life for the bearing.  Bearing manufactures have formulas to calculate bearing life for RPM and load.

RE: Maximum load on

The load on the front bearing is greater than the overhung load, and increases with the overhang.  A sophomore in engineering school can tell you how much.  A junior could figure out how much load/overhang will bend the shaft.  Either of them will need a little help from a bearing catalog to predict the bearing life.

An experienced engineer would ask why you can't put a bearing next to the load.
