Ruland MJC25-8/7.5D-A, 8/7.5Dmm Jaw Coupling Hub, Aluminum, Clamp Style with D-Bore, 25.4mm OD, 11.9mm Length

PRODUCT SPECIFICATIONS

Ruland MJC25-8/7.5D-A is a clamp d-bore zero-backlash jaw coupling hub with a 8/7.5D bore, 25.4mm OD, and 35.3mm legnth. The d-bore allows for positive drive in applications where the coupling can not slip. It is a component in a three-piece design consisiting of two aluminum hubs and an elastomeric insert called the spider creating a lightweight low inertia coupling capable of speeds up to 8,000 RPM. This three-piece design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores. Spiders are available in three durometers allowing the user to tailor the performance of the coupling to their application. Ruland jaw couplings have a balanced design for reduced vibration at high speeds. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. MJC25-8/7.5D-A is machined from bar stock that is sourced exclusively from North American mills and is RoHS3 and REACH compliant. It is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Product Notes

Nota 1

Stainless steel hubs are available upon request.

Nota 2

Performance ratings are for guidance only. The user must determine suitability for a particular application.

Nota 3

Torque ratings for the couplings are based on the physical limitations/failure point of the spiders. Under normal/typical conditions the hubs are capable of holding up to the nominal torque of the spiders. Please consult technical support for more assistance.
