Plastic rail

View product details
  • Plastic rails to support Plastic modular chain/Top chain running.
  • A complete line-up of various types available, including ultra-high molecular weight polyethylene chains for general use, plastic chains for superior wear resistance, low friction chains, chains for dry conditions, and others.
  • Application

    Using ultra-high molecular weight polyethylene (UHMW-PE) as the material, it exhibits excellent sliding characteristics and wear resistance.

    A wide variety of products are available and are commonly and widely used for rails.

Ultra high molecular weight polyethylene (UHMW-PE)

Ultra high molecular weight polyethylene

It has excellent properties such as slidability, wear resistance, chemical resistance, impact resistance and non-water absorption, and is widely used for parts of industrial equipment such as rails and linings.

A wide range of sizes is available, including sheets, round bars and rails, as well as fabricated and molded products on request.

Plastic rail specifications

P Plastic Rails :Code: P

  • ・Conventionally used for general-purpose applications; manufactured from UHMW-PE (ultra-high molecular weight polyethylene).
  • ・Recommended for use with stainless steel chains. When used in combination with plastic chains, it is recommended that they be used under wet (lubricated) conditions.
    (Under dry conditions, more wear debris can be generated. )
  • ・Operating Temperature Range :-20~60℃
  • ・Do not use in environments where rail components will be exposed to steam.

PMW Plastic Rails :Code: P MW

  • ・Low friction and wear resistant version of P Series plastic rail. The amount of wear debris generated can be reduced to M Series plastic rail levels.
  • ・Can reduce coefficient of friction of chain to approximately 20% of P Plastic Rail levels.
  • ・Operating Temperature Range :-20~60℃
  • ・Do not use in environments where rail components will be exposed to steam.

M Plastic Rails :Code: M

  • ・Plastic rail specially designed for use in dry environments. Especially recommended when generation of wear dust may be a source of problems.
  • ・Operating Temperature Range :-20~80℃
  • ・Do not use in wet conditions.

PLF Plastic Rails :Code: PLF Low Friction/Anti-Wear Specifications

  • ・Since the coefficient of dynamic friction can be reduced compared to conventional plastic rail, the generation of wear debris in a dry atmosphere is suppressed.
    [10 - 40% lower than PMW Series rails ] [30 - 50% lower than P Series rails ]
  • ・Uses material that conforms to food sanitation regulations (No. 370 of the Ministry of Health and Welfare)
