Item description/product images

DescriptionMaterial:Coupling hub stainless steel 1.4112/1.4305.
Screws nickel plated (on request stainless steel).
Springs chemically nickel plated.
Assembly:The fit shaft to bore should be a transition fit.
The clearance should be min. 0.01 mm and max. 0.03 mm i.e.
Shaft Ø16 j6
Bore Ø16 H7
Diameters smaller than Dmin are possible, however, a sure transfer of the coupling torque is no longer guaranteed.
On request:List required hub bore D1 and D2 with limits or fits separately.
