OPE and OBE Bearing 1

[Finglas]

What's the difference between these two bearings out of curiosity?

Finglas,

What catalogue are you looking at?

Would these be angular contact bearings by any chance?

I know the difference between OBE (Order of the British Empire) and MBE (Member of the British Empire) both of which can be over-bearing - does this help

Was just doing a bit of research on motors yesterday and I came across a picturing of an AC motor and it said the bearings were either OPE or ODE (sorry not OBE). Perhaps they are angular bearings. That would just give the shaft of the motor a little flexibility if that was the case?

Thanks for those funny comments. If it was OBE it could be an old but everlasting bearing. They'd be handy for non-maintenance.

opposite drive end bearing, however that doesn't really fits into this context.

oligo(p- phenylene ethylene) (OPE) bearing
from googling.

another one: Opposite Pulley End

Finglas,

I have seen codes like this applied to angular contact bearings. The problem with these, particularly small ones, is that you have to preload them with some controlled force. Even a small clamping screw can exceed the acceptable loads on small ball bearings. You can use wavy washers or other such spring elements to preload them.

Alternately, you can lap the bearing faces so that when you clamp the bearings face to face, you get the recommended preload. There are multiple ways to assemble these bearings, so there has to be a lapping setup for each configuration, hence some sort of code, such as possibly yours.

I was specifying this stuff out of the FAG spindle bearings catalogue, and I recall that their codes sound a lot like what you are quoting.

I suggest that you contact your motor manufacturer for an explanation. Unless these are special motors of some sort, my explanation is rather unlikely.

I'll bet the arrow was pointing to the non-shaft end of the motor. As pointed out, the bearing on that end of the motor can be referred to as "Opposite Drive End" or "Opposite Pulley End" (both mean the same thing and refer to the position on the motor). The bearings on the shaft end can be referred to as PE or DE
