Wheel bearing loads and duty life

Wheel bearing loads and duty life

Wheel bearing loads and duty life

(OP)
Dear folks,

I am looking for information regarding developing an approximate duty life for wheel bearings.
For example the life of the vehicle could be split into a percentage of braking, normal driving, scrubbing etc.
Does any one know of standards that I could investigate?

Any information will be appreciated.
Best Regards
Eddie

 

RE: Wheel bearing loads and duty life

Timken have some good guidance in their taper roller design guide.

Temperature effects are very important.

Thanks Greg,

I am aware of the bearing life calcs for tapers in the Timken catalogue however I was looking more for standards like SAE for guidance on duty cycles for wheel loads like scrubbing braking etc. for example 100k miles split into the various loads etc. Although I feel this is a highly subjective task.

Any information will be appreciated.
Best Regards
Eddie
