MK5 | Miniature Coupling

With Press-Fit Connection

The MK5 is designed with a single radial clamping screw per hub (ISO 4762) and a blind mate, no wear, press-fit connection.
It has an operating temperature range of -30 degrees to 110 degrees Celsius (-22 to 230 F) and a standard speed rating of 10,000 RPM. Speeds in excess of 10,000 RPM are available with a specially balanced version.
This is a backlash free, electrically insulated, torsionally rigid solution that is easily mounted with 3-axis of misalignment compensation.
These couplings have an infinite life, and are maintenance-free if the technical ratings are not exceeded. The bellows made of highly flexible high-grade stainless steel while the clamping hubs and tapered female segment on the bellows face are aluminum. The tapered segment on the hub face is made from glass-fiber reinforced plastic.
*Non-standard application: Custom designs with varied tolerances, key-ways, non-standard material and bellows are available upon request.
