Toughroller

Product photo
  • Outstanding performance when conveying, transferring, or moving heavy items.
  • Consisting of a frame and endless rollers, the endless rollers (roller, pin, and link plates) wrap around a center plate on the frame. In contrast to a standard bearing, an operating principle behind Toughroller's operation is that a center plate is an inner ring, rollers are balls, link plates and pins are a ball cage, and contact surface is a outer ring.

Application

  • ・Transferring/conveying heavy items.
  • ・When items are conveyed only infrequently and do not warrant conveyor use.
  • ・When efficient use of space is important.
  • ・As a slide guide for long items.

Features

  • ・Stable conveyance with a low center of gravity

    Unit is low so conveyed goods only need to be jacked up a little bit. A low center of gravity allows for stable conveyance.

  • ・Compact yet powerful

    Load is received by multiple rollers, making it compact yet boasting high load capabilities.

  • ・Tough for longer life

    Frame unit has a top plate welded into place, making it extremely strong and durable. Major parts are heat treated for superior wear resistance as well.

  • ・Plastic roller type is line-up.

    Plastic rollers won't scratch a running surface (generally road surfaces) and half weight of steel rollers. Easy to carry

    Are quieter when running than with steel rollers -- no painful screeching sounds

    ※Avoid direct sunlight for plastic roller type.

  • ・Wide variety of options

    We offer an extensive line-up to match any usage application.

  • ・Light running

    Using a same operating principle as bearings, rollers excellent in circularity reduce running resistance, enabling heavy objects to be conveyed with little force.

Types

  • ・Steel Roller Type :Basic Load Allowance :14.7kN(1500kgf)~1961kN(200000kgf)

    Steel roller Toughroller is a compact device with a high load allowance made from a tempered center plate and rollers.

  • ・Plastic Roller Type :Basic Load Allowance :2.94kN(300kgf)~34.3kN(3500kgf)

    Plastic Toughroller uses engineering plastic for its rollers, which gives it increased functionality over the basic features of steel rollers.

    And Tsubaki's Plastic Toughroller Jr. is an economical, lightweight, simple design for easy use.
