MIDWEST FASTENER CORP

MIDWEST FASTENER CORP No. 50 Roller Chain Offset Link 4PK 75865

SKU CH-HM7F-7TJ0M

  • No. 50 roller chain fits standard power transmission drives
  • Four offset links per pack let you adjust chain length

Product Identity

This is a four-pack of No. 50 roller chain offset links manufactured by Midwest Fastener. It suits maintenance teams and equipment operators who need to repair or adjust standard roller chain drives on motorcycles, bicycles, or industrial machinery.

Installation Notes

Each offset link connects two chain ends without a master link, allowing length changes in half-pitch increments. Proper alignment of the pin and roller is essential; a misaligned press fit can bind the joint or cause premature wear.

Compatibility Check

Verify that the existing chain is marked No. 50 so the pitch and roller diameter match these links. Confirm the current chain width and pin diameter correspond to the same standard before fitting the offset links.

Questions about this item

How can I confirm the No. 50 offset links are working correctly after installation?

After fitting the 75865 offset links, run the chain under load and check for smooth articulation at each joint without binding or excessive noise.

What comes in the 4-pack and what additional parts are needed to complete a chain repair?

The pack contains four No. 50 roller chain offset links; you will need matching No. 50 roller chain, master links, and a chain breaker tool to finish the repair.

Which version of the MIDWEST FASTENER offset link should I choose for my application?

Select the 75865 No. 50 offset link when your drive system uses ANSI No. 50 roller chain; other chain sizes require different link numbers.
