Ruland PSR8-2-1.5-SS, 1/8" x 3/32" Four Beam Coupling, Stainless Steel, Set Screw Style, 0.500" OD, 0.750" Length

PRODUCT SPECIFICATIONS

Ruland PSR8-2-1.5-SS is a four beam coupling with 1/8" x 3/32" bores, 0.500" OD, and 0.750" length. It is machined from a single piece of material and feature two sets of two spiral cuts. This gives it higher torque capacity, lower windup, and larger body sizes than single beam couplings. PSR8-2-1.5-SS is well suited for applications such as encoders that require high positioning accuracy. This four beam spiral coupling 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. PSR8-2-1.5-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 is RoHS2 and REACH compliant. PSR8-2-1.5-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.
