MODEL MK6
TECHNICAL SPECIFICATIONS
Press-fit precision metal bellows coup
Properties:
■ electrically insulated
■ self-adjusting
■ no wear
■ easy mounting and dismounting
■ blacklash-free and torsionally rigid
■ low moment of inertia
■ compensates for 3-axis of misalignment
Bellows made of highly flexible high-grade stain­less steel, clamping hub aluminium. Expanding hub and cone (steel)
On one side an expanding shaft with tapered clamping element. On one side a clamping hub. Backlash-free, blind mate press-fit connection (glass-fiber reinforced plastic)
-30° to +120° C (3,6 F to 270 F),
Up to 10,000 rpm, in excess of 10,000 rpm available with balanced version
These couplings have an infinite life, and are maintenance-free if the technical ratings are not exceeded.
On the hub/shaft connection 0.01 to 0.05 mm.
