*Max recommended shaft diameter is based on allowing approximately 3 mm minimum wall thickness around the shaft. Insufficient wall thickness can increase the risk of cracking during machining, installation, or operation. If you’re unsure, enter your shaft diameter in the notes on the Quote Form above and we’ll confirm compatibility.

D270 & D280: Available on request. These sizes are not commonly stocked due to low demand — dimensions and availability will be confirmed at time of enquiry
