Maximum bores can accommodate standard keyways. Larger bores are available where a shallow keyway is used or no keyway is required.
All Type B or C sprockets, up to and including 25 tooth, are with hardened teeth as standard.
For any additional size sprockets with hardened teeth, add “H” before the number of teeth, e.g. PHS 25-1BH9.
