Top Roller Chains

  • Top Roller Chains are Free Flow Chains using taller plates than Double Pitch or RS Chains and freely rotating top rollers.
  • Tsubaki offers a selection of standard series chains as well as Lambda Series (lube-free), SS Series (stainless steel), Poly Steel Series, and NP Series (electroless nickel plated).
  • Refer to the chart below when combining top rollers and base chain rollers

Notes
 1. For the sake of convenience, the base chain is the part of the chain with the top rollers removed.
 2. *1. When using steel top rollers with Lambda Series, the top rollers will require lubrication.
 3.※2チェーン本体がSS仕様の場合、ステンレスローラとなります。

Base chain

1. Standard Series

Base chains available with steel rollers (S, R) and plastic R-rollers.

With steel rollers

・ All rollers use hardened steel.
・ Operating temperature range: -10℃ to 150℃.
・ Requires additional lubrication

With plastic R-rollers

・ The R-roller of the base chain is engineering plastic.
・ Performance with plastic R-rollers.
       Lightweight (40% lighter than with steel rollers)
       Quiet (5-7dB quieter than steel chains)
      Running resistance (30% less running resistance
       than steel chains)
       Roller color: White
       Operating temperature range: -10℃ to 80℃.
      *The area between pins and bushes must generally
       be lubricated.


2. Lambda Series (lube-free)

The bushes of the base chain are oil-impregnated sintered bushes and do not require additional lubrication. (Steel top rollers will require additional lubrication.)

While the allowable load is the same as with standard series, the inner and outer plates have been treated with black oxide for identification purposes.

Operating temperature range: -10℃ to 150℃.

Avoid use around chemicals or in water, or in washing/degreasing applications.

3. Stainless steel series (SS Series)

Stainless steel rollers (S, R) and plastic R-rollers available.

Stainless steel rollers

・ All parts use 18-8SUS (SUS304 equivalent).
・ Operating temperature range: -20℃ to 400℃
・ Requires additional lubrication

With plastic R-rollers

・ The R-roller of the base chain is engineering plastic.
・ Performance with plastic R-rollers.
       Lightweight (40% lighter than with steel rollers)
       Quiet (5-7dB quieter than steel chains)
      Running resistance (30% less running resistance
       than steel chains)
       Roller color: White
       Operating temperature range: -10℃ to 80℃.
      *The area between pins and bushes must generally
       be lubricated.

4. NP Series

Nickel plating available for Standard and Lambda Series

Top roller specifications

1. Engineering plastic roller

Plastic roller

・ Material: Polyacetal (white)

・ Operating temperature range: -20℃ to 80℃

KV rollers

・ Material: Super engineering plastic (black)

・ Operating temperature range: -20℃ to 180℃

2. Steel roller

Steel roller

・ Material: Hardened steel

・ Operating temperature range: -10℃ to 150℃.

・ Lubrication required

Stainless steel roller

・ Material: 18-8SUS (SUS304 equivalent)

・ Operating temperature range: -20℃ to 400℃

・ Lubrication required

Lambda Rollers

・ Material: Steel

・ Operating temperature range: -10℃ to 150℃.

・ Additional lubrication: Not required

※ Requires additional lubrication when base chains are standard series.

Sprocket

Sprockets for Double Pitch Chains with Top Rollers

When the base chain rollers are R-rollers, standard sprockets for Double Pitch Chain (R-rollers) cannot be used as the sprocket teeth contact the top rollers. Therefore, please use a sprocket for top roller chain.

When the base chain rollers are S-rollers, standard sprockets for RF Double Pitch Chain (S-rollers) can be used. When using RS sprockets, only S-rollers can be used, and the sprocket must have 30T or more.
