- This is an all stainless steel spring coupling with single-piece construction. A slit is inserted into a cylindrical material.
- Made of SUS316L superior in corrosion resistance.
- Cleanroom wash/cleanroom packing provided. It is intended for applications that require chemical resistance, such as FPD production equipment and semiconductor devices.
- High flexibility type XSTS-C and short type XWSS-C are standardized.
- XSTS-C has a plate spring formed by a slit allows eccentricity, angular misalignment, and end-play to be accepted.
Application
FPD manufacturing device / Semiconductor manufacturing device / Offshore instrumentPrecautions for Use
In case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft. ⇒Mounting and MaintenanceThere are sizes where the hex socket head bolt exceeds the outer diameter of the coupling and the rotating diameter is larger than the outer diameter. Please be careful of the interference of coupling. Rotation Diameter
