Spindle Bearings | KRW Leipzig

Spindle bearings are self-latching bearings that cannot be disasseled. In addition to radial forces, they can absorb single-sided axial forces as well as, in coination with a second mirror-image arranged angular spindle bearing, two-sided axial forces and radial forces. For coined bearing sets there is a distinction between O-, X-, or

Inner Wheel Bearing Recommendation for a Nuer 84 Spindle

The inner and outer bearing surfaces on a nuer 84 spindle are different diameters. The outer bearing will ride on a 1.00 inch diameter surface and the inner bearing will ride on a 1.378 inch surface. It sounds like you have the correct outer bearing and now are in need of the correct inner bearing. For that you would want the part # L68149

5. Clean and inspect the wheel bearing cups and cones, race, spindle bearing and seal journals on the spindle, and hub. Bearings should be cleaned in a suitable non-flammable solvent and dried with either compressed air or a lint-free rag. If compressed air is used, do not spin dry the bearings as the rollers may score due to lack of lubricant.
