Wear rings

We can use either. Please specify which you use so we can send you the wear rings you want. We will always confirm back to you the sizes ordered so there is no misunderstanding.

Our freshly manufactured phenolic wear rings are light beige, almost yellow in colour but after a matter of days or weeks they start to darken towards a dark oak or mahogany colour.

This can be caused by several processes:

  • Oxidation occurs naturally within the phenolic resin.
  • A process called Ultraviolet Light Crosslinking occurs because the phenolic resins used in making wear rings are not light stable.
  • The cotton fabric used in the composite, being organic, will darken over time.

This is just a colour issue and doesn't affect the operational properties of the wear ring.

Wear strips

We supply coiled strip in 5m and 10m lengths.

No, the 10m strip is made in one continuous piece so there are no weak points.

We can use either although Strip Dimensions seems to be more common. Please specify which you use so we can send you the strip you want. We will always confirm back to you the sizes ordered so there is no misunderstanding.

Tube

When you place your order, or request a quotation, you have a couple of options. You can either specify the dimensions you wish to machine to and we will provide tube(s) with a smaller inner diameter, larger outer diameter and longer than the desired finished article, or you can specify the size of the tube you require.

Special

Specials, in this instance, are any parts we have to order specifically. Usually Specials are not something we'd hold in stock since the materials and dimensions involved are often project specific but this is dependant on your needs, timescales and costs among other things.

Items included under the generic banner 'Specials' might include, but are not limited to:

  • flanged bearings (unsplit wear rings),
  • wear rings with unusual cuts (eg step cuts) or with machined grooves (eg lubrication channels seen more often on larger wear rings and bearings),
  • extra large items, such as rings with diameters > 1m,
  • wear plates,
  • spherical bearings.

Normally we would request that you send engineering drawings with your required specifications and we would have the part/parts manufactured to those drawings.
