Double pitch with​Top Roller

製品写真
  • Double pitch with top roller is a free flow type with Double pitch plate extended to the top and a freely rotating top roller attached to it.
    It's a chain.
  • The width of the chain itself is smaller than other free flow chains, and the top roller is supported by plates on both sides, making it a sturdy free flow chain.
    Suitable for conveyors.
  • 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.

Purpose

  • It is suitable for transporting heavy objects at low speeds, and is widely used in automobile production facilities in particular.

Note
1. For convenience, the term "chain body" refers to the entire chain excluding the top roller.
2. *1 Even if the chain itself is a lambda specification, the steel top rollers require oiling.
3. *2 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.

In the case of double pitch chain with top rollers (main body R rollers), a special sprocket is required as the teeth of a standard Double pitch sprocket (for R rollers) will come into contact with the top roller.

For S-rollers, use standard steel Double pitch sprockets.

If the sprocket has 30 or more teeth, a standard steel RS sprocket can be used.

Please see the chain and sprocket compatibility chart here.
