- Form L DIN 319 ball knobs are used where the mating part does not have a thread. They are lightly tapped onto the mating part (shaft tolerance h9, shaft end lightly chamfered) using a soft faced hammer and hold with adhesive.
- The tolerance ring is supplied loose for self-installation.
- As the material thermoset is very brittle, where possible the thermoplastic versions (only Form M size 16 to 40 mm) should be preferred.
- Other versions and colours on request.
