The separable components of SKF thrust ball bearings are interchangeable ( fig. 3, fig. 4 ). This facilitates mounting and dismounting, and maintenance inspections. Bearings with sphered housing washer (s) ( fig. 5) can accommodate initial misalignment. Shaft washers have a ground bore to enable an interference fit.

Then, I proceeded to mill off a section of the disc from the side opposite the 1/4" pin: It was easy enough to set the wheel back on my vise with the bronze slider in place, and test the balance: A few trips to the mill and I had it balanced rather well, I think. This is the drive shaft, a simple piece of 3/4" drill rod.

roller bearings. So roller bearings operate slower with heavier loads. • Types of Loading Radial bearings are primarily designed for carrying radial loads. A radial load is a pressing force that is perpendicular to the shaft. A thrust or axial load is a force that is parallel to the shaft. Ball & Roller Bearings 5 Radial Load Thrust or Axial Load

and the bearing's cross section dimensions. 5. Vibration causes grease to feed more freely into the rolling elements' path, where it is worked and heated excessively. This reduces grease life, especially in high speed bearings. Churning and shearing in bearings "mills down" some greases, which become fluid enough to leak excessively.
