SLEEVES

Introduction

Sleeves are an efficient and cost-effective solution to wear problems on the shaft. Press-fitted onto the shaft, the

sleeves meet the hardness and surface roughness constraints and the dimensions of the rotary seal in contact do

not need to be reviewed. We provide both standard sleeves and sleeves that are suitable for use in highly corrosive

environments.

Assembly recommendations

Please refer to the instructions below to correctly fit the sleeves:

• Clean the soiled areas of the shaft at the point of

contact with the sealing lip of the ring. File down all

burrs or rough areas to ensure that the sleeve does

not prematurely deteriorate when fitted in a groove or

any other part.

• Using a calliper, measure the diameter of the shaft in

3 different positions and check that the average over

these 3 measurements indicates a value that complies

with the recommended dimensional range. If that is

the case, the sleeve will have a sufficiently tight fit on

the shaft to prevent any possible sliding.

• Determine and mark where the sleeve must be

positioned to cover the worn area, up to the end of

the shaft.

• The shallow wear grooves do not need to be filled.

It is, however, possible to apply a sealing product to

the inside diameter of the sleeve. Clean off any surplus

product.

• Deeper grooves can be filled with a metal-epoxy

powder. Install the sleeve before the product hardens.

Remove the surplus product.

• When mounting the sleeve, the mechanical body

must be shut down.

• If the collar must be removed after installation, cut

before installing part of the thinnest area using the

outside diameter of the sleeve.

• Position the sleeve in the mounting tool; it must

be inserted into the shaft in its entirety. Use a mallet

to tap on its centre, until the sleeve covers the worn

shaft. Ensure that the mounting tool is dimensionally

compatible, so as to insert the sleeve without

distorting it.

• Ensure that the outside of the sleeve has not been

damaged during fitting. Its surface roughness and

its cleanliness are two elements that determine the

correct operation of the seal.

• The length of the sleeve must not exceed the full

length of the shaft, excluding the chamfer.
