G8 Heavy Duty Drive Chains

Tsubaki Super (Heavy Duty) Drive Chains offer high maximum allowable loads for use in compact systems

tsubaki-g8-heavy-duty-170x170.jpg

Tsubaki offers a variety of heavy duty and Super Chains to provide users with a higher maximum allowable load, high shock absorption, higher fatigue strength, and higher tensile strength than standard RS Roller Chains. This enables users to go one or two sizes down to design more compact systems.

Useful information
Notice: Super Chain, RS-HT, Super-H drive chains have been upgraded with higher fatigue strength.

Applications

Features and Use

Item/Model Super Roller Chain RS-HT Chain Super-H Roller Chain Ultra Super Chain
Main applications For heavy-duty transmission, lifting
Features * High kW ratings
* High shock absorption
* Can use one size smaller RS Roller Chain
* High kW ratings
* High tensile strength
* High fatigue strength
* High tensile strength
* High shock absorption
* Ultra Super Chains have the highest tensile strength and shock absorption of any Tsubaki roller chain. For drives that require compact designs.
* Able to use two sizes smaller RS Roller Chain.
Example applications e.g Construction machinery, farm equipment, lifting mechanisms, port equipment, tower parking, etc.
Offset links 4POL can only be used for single-strand chain. Offset links are not available. Use an even number of links.
Sprocket Sprockets for RS Roller Chain can be used for multi-strand and single strand chain. * Sprockets for RS Roller Chain can be used for single strand chain.
* Sprockets for RS Roller Chain cannot be used for RS-HT multi-strand chain and Super-H Roller Chain.
* Small sprockets must have hardened teeth.
* Use sprockets made of S35C or higher carbon steel.
* Sprockets for RS Roller Chain can be used if the usage conditions and chain size of the chain being replaced remain the same.
* Tough Tooth sprockets that are optimal for Heavy Duty Chain are available.
