Data sheetGeneral Description
SUPERBOLT® Bearing Locknuts of the NM Series are directly interchangeable with standard locknuts DIN 981 and KM-series locknuts of the bearing manufacturers. They are ideal for jacking bearings into place. They can also clamp whole shaft assemblies.
Other than ordinary locknuts, SUPERBOLT® Bearing Locknuts provide a true pre–load, reducing the risk of failure. They are designed to match the bearing loads of the respective bearing sizes.
