MARTIN SPROCKET & GEAR — MARTIN SPROCKET & GEAR D06B21
- Martin metric double strand solid construction sprockets have proper spacing between chain rows.
- The sprockets are manufactured from high carbon steel.
- Martin does not stack “A” plates on multiples, but instead Martin machines teeth after the chain rows are already in place.
- These plain bore sprockets can easily be bored to a metric or standard size to fit your application.
- Keyways, set screws and harden teeth are quick alterations that can be made.
