Plastic Rails

Plastic rail to support top chain running.

Tsubaki offers a complete line-up of plastic rails, including a versatile ultra-high molecular polyethylene type and one using a low friction, low wear plastic type, and specially designed for use in dry environments.

We will be discontinuing sales of some models on orders from September 30, 2019.

1. Ultra-high molecular polyethylene (UHMW-PE)

1. Ultra-high molecular polyethylene (UHMW-PE)

Features excellent slideability, wear resistance, chemical resistance, and impact resistance, and will not absorb water. They are widely used as rails, linings, and as industrial equipment parts.

2. Plastic rail specifications

P Series plastic rails (Code: P)
  • A plastic rail featuring ultra-high molecular polyethylene (UHMWPE), traditionally used for versatile products.
  • Recommended for use with stainless steel chains. When using together with plastic chains, we recommend using under wet conditions. (There is a possibility that more wear debris will be generated under dry conditions.)
  • Operating temperature range: -20 to 60°C
  • Not for use in contact with steam.
PMW Series plastic rail (Code: PMW)
  • A low friction, wear resistant version of the P Series plastic rail. The amount of wear debris generated can be brought down to M Series plastic rail levels.
  • The coefficient of friction on the chain can be reduced by 20% of traditional P Series plastic rails.
  • Operating temperature range: -20 to 60°C
  • Not for use in contact with steam.
M Series plastic rail (Code: M)
  • Plastic rail specially designed for use in dry environments. Recommended especially for applications where wear debris needs to be avoided.
  • Operating temperature range: -20 to 80°C
  • Not for use in wet environments.
PLF Series plastic rail (Code: PLF) -- Low friction, wear resistant series
  • Can reduce the coefficient of dynamic friction compared to traditional plastic rails, and so suppresses the generation of wear debris in dry environments.
  • 10 - 40% lower than PMW Series rails, 30 - 50% lower than P Series rails.
