Ruland FSR24-12-6-SS, 3/4" x 3/8" Six Beam Coupling, Stainless Steel, Set Screw Style, 1.500" OD, 2.250" Length

PRODUCT SPECIFICATIONS

Ruland FSR24-12-6-SS is a six beam coupling with 3/4" x 3/8" bores, 1.500" OD, and 2.250" 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. FSR24-12-6-SS is zero-backlash and has a balanced design for reduced vibration at high speeds of up to 6,000 RPM. All hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. FSR24-12-6-SS is made from 303 stainless steel for increased torque capacity. It is machined from bar stock that is sourced exclusively from North American mills and RoHS2 and REACH compliant. FSR24-12-6-SS is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Product Notes

Note 1

Torque ratings are at maximum misalignment.

Note 2

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

Note 3

Torque ratings for the couplings are based on the physical limitations/failure point of the machined beams. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the machined beams. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the machined beams. Please consult technical support for more assistance.
