Teeth specifications
Hardened teeth specifications
All Tough Tooth sprockets have hardened teeth.
An optional special coating that enhances tooth hardness is also available.
Optimal for harsh usage conditions and environments where you want to reduce both sprocket and chain replacement frequency.

Options (MTO product)
Special coating
Sprocket features a coating that provides over HV800 hardness to the teeth to increase wear resistance. Effective in harsh usage conditions and environments where sprocket replacement frequency is high.
Shaft bore finishing service
Shaft bore finishing available as an MTO product.
Shaft set delivery
Based on customer drawings we can quote the shaft, manufacture, and deliver as a set with the sprocket. An inspection report can reduce man-hours and cost for inspection and integration at the customer’s site.
