Shims for Ball Bearings
For technical drawings and 3-D models, click on a part number.
Adjust spacing between bearings and other components on shafts. These shims are sized to fit the outer rim of a bearing.
316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
18-8 stainless steel shims offer good corrosion resistance.
Brass shims are corrosion resistant and nonmagnetic.
