2-1-3. Wearstrip mounting

  • ・The wearstrip should be supported by the frame with zero clearance.
  • ・Since the wearstrips are made of ultra-high molecular weight polyethylene (UHMW-PE), they elongate greatly with temperature and/or humidity, requiring that each be mounted with just one screw at the end. Leave a clearance of around 5 mm at the joint part between the two wearstrips. Wearstrip mounting
  • ・Square steel or stainless steel parts should be provided on both sides of the wearstrip to prevent the roller table from being dislocated. Wearstrip mounting

    Note)

    • Part a: Prevents interference with the plastic roller of the roller table.
    • Part b: Prevents interference with the neighboring top chain and other parts.

Coefficients of linear expansion

  • Plastic rail (P rail) 、PLF rail ：20×10-5/℃
  • M rail ：9×10-5/℃

Note)

  • 1. Operating temperature range
    Plastic rail (P rail) 、PLF rail ：-20～60℃
    M rail ：-20～80℃
  • 2. Do not use in environments where wearstrip components will be exposed to steam.

2-2. Wearstrip on return-way

2-2-1. Common configuration for both ST and RT roller

Common configuration for both ST and RT roller
  • ・The curve radius R at both ends should be as shown in the table below.
    Size Curve radius R
    ST300, RT300, RT400, RT500, RT600 200 or more
    ST400 250 or more
    ST500 300 or more
  • ・Slack as shown in the above figure should be provided beneath the drive sprocket during conveyor operation.
  • ・Select a configuration for the wearstrip that prevents the plastic rollers of a given row from wearing down.
  • ・The width of the wearstrip (W1) should be shorter than C1 (effective width) by 10 mm.
  • ・Select UHMW-PE (ultra-high molecular weight polyethylene) for the material of the wearstrip.
