Front Spindle Bearings

(1/4) > >>

PSweeney:
I have an issue with the hubs on my front wheels.  Basically the inner bearing seat machined into the hub for the bearing is not deep enough and I don't have room to run an oil seal.  The wheels are fully laced and assembled hence I'm reluctant to pull them apart to turn the seat deeper.  An option I'm considering is using a rubber sealed ball bearing for the inner.  Would there be any issues running a ball bearing inner and taper roller outer ?

dreracecar:
I have been running inner and outer sealed ball bearings for years without issues, but you cant mix them because of adjusting the preload and each has the own setting. If you do go with the sealed ball bearings you have to work on shimming or trimming (spindal nut) to get the preload correct and still have proper location for the cotter key

PSweeney:
thanks Bruce, I suspected that might be the case. 

How do you pre-load sealed ball bearings on an anglia spindle ?.  The inner bearing locates on the spindle shoulder and the outer either sits where the wheel hub dictates.  Do you use a spacer in between the two bearings ?

JrFuel Hayden:
If your hubs have a shoulder where the tapered bearing race sits, then just go to a bearing supply with your races out and find ball bearing to fit, no spacer is needed because your hub bearing shoulder will set the bearing locations.  I have done that a number of times trying to fit some older style hubs on early Ford, Anglia, Fiat spindles. The sealed ball bearings are a better way to go over tapered, because of rolling resistance, now if you are going to race in circles, tapered is better.

Making an inner spacer can be done but is tricky. I just install the bearings in the hub against the shoulders in the hubs, install the wheel onto the spindle, tighten the nut and spin the wheel by hand. If the nut is to tight, when the rotation stops it will be abrubt and almost counter rotates but does not, just back off till the wheel stops smooth. Inspect the cotter key hole for thru passage or sand back-side of nut till passage is there.
