PRODUCT SPECIFICATIONS

Ruland MSPC-14-14-F is a two-piece rigid coupling with 14mm x 14mm bores, 34mm OD, 50mm length, and 5mm x 5mm keyways. It has precision honed bores to ensure they are collinear and do not introduce misalignment or vibration into the system making it suitable for high precision servo appliactions as well as shaft to shaft connections. MSPC-14-14-F has opposing hardware for a balanced design. Proprietary Nypatch® anti-vibration coating on hardware allows for even seating of the screw, repeated screw installations, prevents galling, and maintains high holding power. It eliminates the need to treat screws upon receipt greatly reducing installation time. Forged screws test beyond DIN 912 12.9 standards to ensure maximum holding power. Tightly controlled bore tolerance of +.050mm/+.012mm is maintained. MSPC-14-14-F is made from 1215 lead-free steel with a proprietary black oxide finish that produces a fine glossy finish while increasing holding power and resisting corrosion. It is machined from solid bar stock that is sourced exclusively from North American mills and is RoHS3 and REACH compliant. MSPC-14-14-F is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Installation Instructions

  1. Align the MSPC-14-14-F two-piece rigid coupling on the two shafts to be connected. There should be no misalignment.
  2. Tighten the Nypatch® screws in two stages, starting with the inside screws. Using a 4.0 mm torque wrench, tighten the inside screws to 4.75 Nm which is half the recommended seating torque.Repeat the process for the outside screws, tightening to half the recommended seating torque.
  3. Be sure to maintain the gap of 1.60 mm between the two halves during installation.
  4. Tighten the screws to the full recommended seating torque of 9.5 Nm following the same pattern, starting with the inside screws first.
  5. For optimum results do not exceed the shaft penetration length of 25.0 mm.
