Ruland FCR16-5-4-A, 5/16" x 1/4" Six Beam Coupling, Aluminum, Clamp Style, 1.000" OD, 1.500" Length

PRODUCT SPECIFICATIONS

Ruland FCR16-5-4-A is a six beam coupling with 5/16" x 1/4" bores, 1.000" OD, and 1.500" length. It is machined from a single piece of material and features two sets of three spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single or four beam couplings and allows for use in light duty power transmission applications such as coupling a servo motor to a lead screw. FCR16-5-4-A is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM. Ruland supplies this spiral coupling with Nypatch® anti-vibration hardware that allows for even seating of the screw, repeated screw installations, prevents galling, and maintains high holding power. All hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. FCR16-5-4-A is made from 7075 aluminum for lightweight and low inertia. It is machined from bar stock that is sourced exclusively from North American mills and RoHS2 and REACH compliant. FCR16-5-4-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
