1. What is TOUGH TOOTH?
- - The tooth base has sufficient strength for the chain and wear resistance has also been improved.
- · The hub has been strengthened, and the allowable surface pressure of the keyway in the shaft hole has been increased by 43%.
Hub strength comparison
Hub transmission capacity comparison
- *The torque is calculated from the allowable surface pressure of the keyway when using one JIS parallel key with the maximum bore diameter.
calculation. - *Comparative example for RS80-SUP-H-1
TOUGH TOOTH special coating specification (optional) is also available.
This sprocket has been coated to increase the hardness of the tooth tips to over HV800, improving wear resistance.
It is effective in harsh usage environments where sprockets need to be replaced frequently.
