Polyurethane Caterpillar Parts

Caterpillar parts made from polyurethane have proven to outwear other materials in particular when abrasion is a factor. It is vastly superior to rubber, plastics and metal in many applications. It has a higher load bearing capacity than any conventional rubber. This makes it an ideal material for load wheels fitted to fork trucks etc, heavy duty couplings, metal forming pads, shock absorbing pads, machine mounts etc. In fact it can be moulded into virtually any form given the correct moulds and tooling are used.

Should your machinery have an abrasion issue resulting in expensive production down time, then replacing the part or parts manufactured in POLYURETHANE will in most cases solve the problem, thus reducing your operational costs. Polymac supplies the mining and earthmoving industries with couplings to suit the Caterpillar scrapers.

Caterpillar uses polyurethane materials in hydraulic seals, struts, track adjusters, arm rests, and other parts. Polymac are able to manufacture and refurbishes a wide range of Caterpillar parts. ranging from engine mounts to turn table wear pads.
Polymac refurbishes all Caterpillar engine mounts using your existing worn out engine mounts. We replace the worn out rubber cushion with a polyurethane cushion. Existing engine mounts which have been refurbishes with polyurethane have shown approximately a 3 times increase in lifespan over a rubber component.

This is achieved by several factors:

 

  • The Polyurethane is fully bonded to the inner core.
  • The outside of the polyurethane is molded to maximize the surface area in contact with the outer shell prior to being pressed into the outer.
  • Polyurethane is inert to most chemicals including those used in the mining/earthmoving industries. e.g. oils, diesel, petrol, greases etc.
  • Eliminate the "play" common to rubber bushings

 

If you have any items that you are having problems, just send a drawing or a new part so that we are able to replicate the item and test for correct durability for Australian conditions.

 

 

 

 

Polyurethane Applications:


Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Because urethane is available in a very broad hardness ranges  it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties. Polyurethane can reduce plant maintenance and OEM product cost. Many applications using this ultra-tough material have cut down-time, maintenance time and cost of parts to a fraction of the previous figures.
Urethanes have better abrasion and tear resistance than rubbers, while offering higher load bearing capacity.
Compared to plastics, urethanes offer superior impact resistance, while offering excellent wear properties and elastic memory.

Urethanes have replaced metals in sleeve bearings, wear plates, sprockets, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements being realized.

APPLICATIONS

Polyurethane can be virtually moulded into any shape or component given the correct design, mould and tooling. Please see a few examples below:

  • Pressing bags and membranes for ceramics
  • Belts
  • Machinery mounts
  • Cutting Surfaces
  • Conveyor Scrapers mining
  • Seals
  • Sound-dampening pads
  • Gaskets
  • Blocks, slabs and bar used for machining small engineering components
  • Ornate street furniture eg bollards, lamposts, litter bins etc
  • Industrial wheel and tyre eg fork trucks, pallet trucks etc
  • Consumable parts for paper converting machinery eg anvil covers etc
  • Roller coverings
  • Conveyor belt scraper blades
  • Moulds for casting concrete products eg paving slabs
  • Abrasive resistant components for shot blasting equipment
  • Shock absorbing pads for pile drivers
  • Suspension bushes for automotive industry
  • Cutting sticks for newspaper industry
  • Wear strips
  • High impact bump stops
  • Flexible drive couplings
  • Quarry screen
  • And much, much more.


Polymac offers more than just custom moulding, our customers gain access to in-house engineering expertise. We provide extensive consultation from initial concepts and problem solving guidance to material selection and tooling.
