  • 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.

Hex Socket Head Cap Screw PEEK (Polyether Ether Ketone)

PEEK's color may vary depending on the lot or other matters.


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.
