*1: Correction of rated torque due to load fluctuation is not required. For more detailed information, please refer to Selection Guidelines.

※ The shaft's slip torque may be smaller than the coupling's rated torque depending on the shaft bore.

*2: These are values with max. bore diameter.

● All products are provided with hex socket head cap screw.
● Recommended tolerance for shaft diameters is h6 and h7.
● In case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft. ⇒Mounting and Maintenance
● Bore and keyway modifications are available on request. Please take advantage of our modification services.

Slip torque

As in the table below, the clamping type MSXP-C has different slip torque according to the bore diameter. Take care during selection.

Unit : N・m

Part Number Bore Diameter (mm)
6 8 10 12 14 15
MSXP-25C 0.5 0.6 0.7
MSXP-30C 0.8 1.1 1.5
MSXP-36C 0.7 1.2 1.8 2.2

These are test values based on the conditions of shaft dimensional allowance: h7, hardness: 34-40 HRC, and screw tightening torque of the values described in MSXP-C dimension tables. They are not guaranteed values.
Slip torque changes with usage conditions. Carry out tests under conditions similar to actual conditions in advance.

◎: Excellent ○: Very good

  • This is a resin spring coupling with single-piece construction.
  • It can be used in an environment or cleanroom where heat resistance and chemical resistance are required, such as FPD manufacturing equipment.
  • PEEK superior in physical and chemical properties is adopted. Outgas quantity is extremely low.
  • A plate spring formed by a slit allows eccentricity, angular misalignment, and end-play to be accepted.
