Heavy Duty Roller Chains

Tsubaki s Heavy Duty Roller Chains come in a wide array of products. Their high maximum
allowable load make them commonly used in compact transmission systems.

2. Uses

Use Tsubaki Heavy Duty Roller Chains when capacity exceeds that of RS Roller Chains, such as in:
    1. Harsh environments where the chain will be subjected to heavy impact.
    2. Compact drives for equipment or machines that must work in tight spaces.
    3. When higher transmission power, allowable load or tensile strength is required.
    4. When a lower rate of elastic elongation is required.

Note
Tsubaki s Heavy Duty Roller Chains are designed for low to mediumSpeed heavy-duty transmission. RS Roller Chain should be used inspeed ranges not appearing in the kilowatt rattings tables.
Example applications Construction machinery, farm equipment, lifting mechanisms, port equipment, parking structures, etc.
Offset links Single-strand Offset links are not available. Use an even number of links.
