Expanding rings


Application: Expanding rings are used for protecting cutter bits of shearer machines or other mining equipment.

We manufacture several types of expanding rings. Expanding rings with PR Ø30Z and Ø38Z locks are always in stock.

We also manufacture Ø17 and Ø21 expanding rings on request.

If you need expanding rings in other sizes, please contact us.

Below are PDF files with engineering drawings of PR Ø17, Ø30Z and Ø38Z expanding rings.
