SKF KMT 0 M10x0.75 - Precision Bearing Lock Nut

SKF KMT 0 M10x0.75 - Precision Bearing Lock Nut

SKF KMT 0 is a precision bearing lock nut with an M10x0.75 thread and three equally spaced locking pins. It belongs to the SKF KMT series designed for accurate axial location of bearings and other components on a shaft. The integrated locking system secures the nut without requiring a conventional locking washer and keyway, providing a compact solution for precision bearing arrangements.

Technical data - SKF KMT 0

What does SKF KMT 0 mean?

KMT identifies the SKF series of precision lock nuts using an integrated locking system with locking pins.

0 identifies the nut size within the KMT series.

SKF KMT 0 has the thread:

M10x0.75

This is a metric fine thread with a nominal diameter of 10 mm and a pitch of 0.75 mm.

SKF KMT 0 design

KMT 0 is not a conventional hexagonal nut or a standard KM bearing lock nut.

The SKF KMT design uses three equally spaced locking pins positioned around the circumference of the nut.

Each locking pin is pressed against the shaft thread by a set screw.

This arrangement allows the nut to be secured in the required axial position without using a conventional locking washer.

Three locking pins

A key feature of SKF KMT 0 is its system of three equally spaced locking pins.

After the nut has been positioned, the set screws press the locking pins against the shaft thread.

This locking principle:

• secures the nut against rotation

• enables accurate axial positioning

• eliminates the need for a conventional locking washer

• eliminates the need for the conventional keyway associated with traditional KM lock nut arrangements

• provides an integrated locking solution

The three-point arrangement distributes the locking action around the nut.

What is SKF KMT 0 used for?

SKF KMT precision lock nuts are designed for accurate axial location of components on threaded shafts.

They can be used for axial location of:

• bearings

• bearing rings

• components associated with bearing arrangements

• other machine components requiring accurate axial positioning

The KMT series is particularly useful where accurate positioning and secure locking are important.

M10x0.75 thread

SKF KMT 0 has an:

M10x0.75

thread.

This is one of the most important parameters when identifying or replacing the nut.

Both thread diameter and pitch must correspond to the shaft thread.

A nut with an M10 thread but a different pitch is not a direct replacement for SKF KMT 0.

SKF KMT 0 dimensions

SKF specifies the following dimensions:

• G = M10x0.75

• d1 = 23 mm

• d3 = 28 mm

• d4 = 11 mm

• d5 = 21 mm

• B = 14 mm

• b = 4 mm

• h = 2 mm

• M = 24 mm

When designing or replacing the nut, both the thread and the available installation space should be checked.

Static axial load carrying capacity - 35 kN

SKF specifies a static axial load carrying capacity of:

35 kN

for KMT 0.

This parameter relates to the axial load carrying capability of the lock nut according to the SKF product specification.

It should not be confused with the dynamic or static load rating of the bearing being located by the nut.

M5 set screws

SKF KMT 0 uses:

M5 set screws

SKF specifies a recommended tightening torque of:

4.5 Nm

for the set screws.

Correct tightening is important to achieve reliable locking of the nut on the shaft.

SKF HN 2-3 hook spanner

SKF specifies:

HN 2-3

as the suitable hook spanner for KMT 0.

Using the appropriate tool facilitates correct installation and helps prevent damage to the nut during tightening or removal.

SKF KMT 0 vs KM lock nut

KMT 0 should not be confused with a conventional SKF KM series lock nut.

KMT is a precision lock nut with an integrated locking mechanism.

Traditional KM lock nuts use a different locking arrangement.

The differences include:

• nut construction

• locking method

• dimensions

• mounting method

• associated locking components

• application requirements

A replacement should therefore not be selected solely on the basis of thread diameter.

SKF KMT vs KMTA

SKF also offers the KMTA series of precision lock nuts.

KMT and KMTA belong to SKF's precision lock nut range but differ in their design and dimensions.

When considering an alternative, verify:

• exact designation

• thread

• overall dimensions

• locking arrangement

• available installation space

• axial load requirements

KMT and KMTA should not automatically be considered interchangeable.

Why use a precision lock nut?

Accurate axial positioning can be important in bearing arrangements where the location of the bearing or another shaft component must be carefully controlled.

A precision lock nut provides a controlled method of:

• positioning components axially

• securing their position

• retaining bearings on a threaded shaft

• creating a compact locking arrangement

The integrated locking mechanism of the KMT series reduces the number of separate locking components required.

For technical selection, the exact designation and thread should always be verified.

How to select a replacement for SKF KMT 0

When selecting an alternative precision lock nut, check:

• M10x0.75 thread

• thread pitch

• precision lock nut design

• locking principle

• overall dimensions

• available mounting space

• required axial load capacity

• positioning requirements

• access to the locking screws

• installation method

Matching the M10x0.75 thread alone does not guarantee complete interchangeability.

Mounting SKF KMT 0

Before installation, inspect and clean:

• shaft thread

• nut thread

• abutment surfaces

• locking pins

• set screws

The nut should first be positioned according to the requirements of the bearing arrangement.

After the required axial position has been obtained, the locking mechanism can be secured.

SKF specifies 4.5 Nm as the recommended tightening torque for the M5 set screws.

SKF identifies the HN 2-3 hook spanner as suitable for KMT 0.

Installation should be carried out without damaging the shaft thread, nut thread or locking components.
