Nuts DIVERS KM0

The KM0 nut from Hülsen, with a 10 mm bore and an 18 mm external diameter, is used for the axial securing of compact shaft bearings.

The KM0 nut is a compact groove nut designed for securing roller bearings and gearbox components onto shafts. The component has a 10 mm bore, an outer diameter of 18 mm and a width of 4 mm. Manufactured from standard roller bearing steel (100Cr6), this fastener is characterised by its dimensional stability and strength in mechanical engineering and workshop applications.

What is the KM0 slotted nut suitable for?

Design engineers and maintenance technicians primarily use the KM0 nut for the axial fixation of rolling bearings on cylindrical shaft sections. Thanks to its compact width of 4 mm, the component requires very little axial installation space. Typical applications include jigs, small gear units, spindle bearings and machine tool construction. The slotted nut helps to ensure that the inner rings of bearings remain in their intended position on the shaft.

What is important when using the KM0 nut?

It is important for proper function that the shaft’s connecting dimensions are correct, matched to the 10 mm bore and the 4 mm width. The 100Cr6 rolling bearing steel provides high strength and load-bearing capacity for the threads. For correct installation, a suitable hook spanner engages positively with the grooves arranged around the circumference. Furthermore, the design must include a suitable locking mechanism to prevent accidental loosening, so that the axial position of the bearing assembly is maintained during operation.
