Double Pitch Chain with outboard rollers

Product Photos
  • Double Pitch Chain with outboard rollers are free-flow chains in which the pins of Double pitch are extended and free-rotating outboard roller are attached to them.
  • Since multiple outboard roller can be attached, it is suitable for conveyors that directly carry small transported items.
  • Standard Series, lambda (Lube-free) specifications, and SS (stainless steel) specifications are available.
  • * NP Series (nickel plating) are also available, so please contact us for details.

Features

  • - Equipped with outboard roller, it is suitable for making conveyors more compact.
  • - Back venting is possible, making the return side layout easier.
  • -Since multiple outboard roller can be attached, it is also suitable for conveyors that place small transported items directly on outboard roller.

Position diagram for staggered type installation Position diagram for parallel mounting
  • ・The diagram shows an example with staggered outboard roller on every link.
  • ・When staggered type every link, the standard installation of plastic brake rollers is every 3 links (diagonal lines in the diagram).
  • The diagram shows an example of parallel outboard roller every two links. SR can be installed at intervals of more than every two links.

Note
1. For convenience, the term "chain body" refers to the entire chain excluding outboard roller.
2. *1 Even if the chain itself is a lambda chain, the steel outboard roller must be oiled.
3. Only outboard roller mounting pin (※2) is made of precipitation hardening stainless steel.
4. When the conductive roller and chain body are NP Series, the brake is a spring brake.
5. If outboard roller are KV rollers, the main rollers will be S rollers.
6. *3 If the chain body is SS Series, the rollers will be stainless steel.

When selecting sprocket specifications

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

For Double Pitch Chain with outboard rollers, please use standard steel Double pitch sprockets.

If the sprocket has 30 or more teeth on the S roller, an RS sprocket can be used.

Please see the chain and sprocket compatibility chart here.

Number of links per unit

Unless otherwise specified, chains with outboard roller will be delivered in units of 1 unit (1 chain length).
