Applications & selection
Typical uses
- Keyed rotary assemblies
- Replacement sets
Industries: Paper mills.
Selecting the right construction
Supply bush-and-ring dimensions, keyway details and mating shaft information. Confirm the stainless-steel key specification and whether a complete replacement set is required.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
