RS Chain with outboard rollers

Product photo
  • A free flow chain using an RS Chain base with an extended pin with freely rotating outboard rollers attached.
  • Since numerous rollers can be installed, Outboard Roller Chain is suitable for conveyors on which small objects are placed directly.
  • We have a lineup of Standard specifications, Lambda (lube-free) specifications, and SS (stainless steel) specifications, and Poly Steel sspecifications..
  • *We also manufacture NP specifications (nickel plating), so please contact us.

Features

  • ・Outboard rollers allow for a compact conveyor.
  • ・The ability to flex backwards allows easy layout on the return side.
  • ・Multiple outboard rollers can be installed, making the chain ideal for conveyors where small items are directly conveyed on the outboard rollers.

About each specification

Standard Series

  • ・The base chain is steel, and steel base chain rollers are standard.
  • ・Base chain uses heat treated hardened steel for all parts.
  • ・Outboard rollers available in engineering plastic (plastic rollers, plastic brake rollers, electroconductive rollers) and steel.
  • ・Operating Temperature Range :-10℃~150℃
  • ・Requires additional lubrication

Lambda (Lube-free) specifications

  • ・Uses special sintered oil-impregnated bushes for lube-free, long life operation.
    ※Lubrication is required on steel outboard rollers.
  • ・While it has the same allowable load as standard series, the inner and outer plates have been treated with a black oxide coating for identification purposes.
  • ・Operating Temperature Range :-10℃~150℃
  • ・Avoid use around chemicals or in water, or in washing/degreasing applications.
  • ・Outboard rollers available in engineering plastic (plastic rollers, plastic brake rollers, electroconductive rollers) and steel.

SS (Stainless Steel) specifications

  • ・All parts use 18-8SUS(SUS304 equivalent) stainless steel for corrosion resistance, except for the pin which uses precipitation hardened stainless steel.
  • ・Base chain and base chain rollers are stainless steel for corrosion resistance.
  • ・Operating Temperature Range :-20℃~400℃
  • ・Requires additional lubrication

Poly Steel Chain

  • ・Made up of engineering plastic inner links and 18-8SUS(SUS304 equivalent) stainless steel outer links, with precipitation hardened stainless steel for the pins.
  • ・Lube-free, corrosion resistant.
  • ・50% lighter than steel and 5dB quieter.
  • ・Operating Temperature Range :-20℃~80℃
  • ・No offset links available. Engineering plastic is white.

  • ・"X" indicates a press fit.

Attachment positioning of outboard rollers

When staggered When attached in a crosswise pattern.
Staggered installation Parallel installation
  • ・The diagram shows an example of outboard rollers attached every link in a staggered pattern.
  • ・When outboard rollers are attached every link in a staggered installation, plastic brake rollers are normally attached every three links (cross-hatched rollers in diagram).
  • ・Example of parallel installation with outboard rollers attached every other link. Outboard rollers can be attached freely, but not every link.
  • ・When attached in parallel every other link, plastic brake rollers are normally attached every six links (cross-hatched rollers in diagram).

Notes
 1. For the sake of convenience, the base chain is the part of the chain with the outboard rollers removed.
 2. ※1 Steel outboard rollers require additional lubrication, even if the base chain is Lambda Chain.
 3. ※2 Only the pin attaching the outboard rollers to the chain is precipitation hardened stainless steel.
 4. Brakes used with electroconductive rollers and when the base chain is NP Series are spring brakes.
 5. Base chain rollers are S-rollers when KV Series outboard rollers are used.
 6. ※3 If the chain base is SS specification, it will be a stainless steel roller.

When selecting sprocket specifications

It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used.

RS sprockets having a small number of teeth (in the table below) cannot be used with RS chain with outboard rollers because the sprocket hub comes in contact with the outboard roller.

When using RS sprockets with small numbers of teeth, finish the hub diameter as per the chart below, or use as is with larger numbers of teeth.
