GWB DKN-S

Version with clamping hub and expanding mandrel

The DKN metal bellows coupling has an expanding mandrel for establishing a frictional connection to a hollow shaft. The clamping mechanism relies on an inner cone and an axial, internal clamping screw. In all other respects, the design is similar to the standard DKN type.

• Metal bellows made of stainless steel, aluminium hubs
• The shaft tolerance should be within a fit tolerance of “g6” or “h7”
• The contact surfaces must be free of oil and grease
• Optional special version in stainless steel
• For the bore tolerance, we recommend a fit tolerance of H7
