Lock nuts for rolling bearings, from M15x1 to M130x2

Lock nuts hold a rolling bearing in place on a shaft or adapter sleeve, so the bearing cannot shift axially. Fitters and maintenance technicians use them when mounting and replacing bearings in pumps, fans, conveyors and other drives. This category holds SKF lock nuts from the KM and KMT series.

The KM lock nut is the standard version with a slim build. The KMT version is wider and heavier for the same thread: KM 4 and KMT 4 both have M20x1, but the KMT is 18 mm wide against 6 mm. Choose the KMT where space allows and the nut has to carry more.

Select the nut on the thread of the shaft or sleeve. It is metric fine and appears in the name as diameter x pitch, for example M50x1.5 or M80x2. The dimensions in the product name then give bore, outside diameter and width in mm. These nuts are part of the accessories and spare parts for rolling and plain bearings, alongside the thrust bearing washers that carry the axial load in a needle roller thrust bearing.
