  • Corrosion Resistant Conveyor Chain

GSA Series

Higher model of GSA Series (Advanced model)

Improved 2x the bush-roller wear resistance, 1.5x the pin-bush wear resistance, and 1.3x the maximum allowable tensile strength and the roller allowable load of R roller, F roller than GS Series

Operating temperature range: -20°C* to 200°C

Contact a Tsubaki representative when using below -20°C

2. Features

GSA Series has better wear resistance and a higher maximum allowable load than GS Series.

1.5x better pin-bush wear resistance

Pin-bush wear resistance (In-house test comparison)

2x bush-roller wear resistance

Bush-roller wear resistance (In-house test comparison)

1.3x the maximum allowable tensile strength, R roller and F roller allowable load

Comparison of the maximum allowable tensile strength

Maximum allowable load is the numerical value set by fatigue limit, allowable surface pressure, etc.

3. Table of Sizes and Strength

  • Maximum allowable load is a value calculated based on Tsubaki in-house standards and is calculated strength. As long as there are no other constraints, maximum allowable load is used in selecting large size conveyor chain. This value will differ by manufacturer and is not a guaranteed value.
  • Contact a Tsubaki representative for average tensile strength.
