Characteristics
- Property
XSTS XWSS Low Particle ◎ ◎ Vacuum-supported ○ ○ Less Outgas ○ ○ Heat-resistance ○ ○ Chemical-proof ◎ ◎ Zero Backlash ◎ ◎ High Torque ○ ○ Allowable Misalignment ○ – Corrosion resistance (all stainless steel) ◎ ◎ ◎: Excellent ○: Very good
- This is an all stainless steel spring coupling with single-piece construction. A slit is inserted into a cylindrical material.
- Clean washing and clean packaging are completed. It can be used in an environment where chemical resistance is required, such as FPD manufacturing device and semiconductor manufacturing device.
- High flexibility type XSTS and short type XWSS are standardized.
- In XSTS, 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 instrument
Technical Information
Characteristics
| Material code | Characteristics |
|---|---|
| SUS304 | This features smaller amount of carbon and is superior in corrosion resistance and weldability. This has good corrosion resistance and acid resistance This is the most standard product among austenitic stainless steel. |
| SUS316 | as well as high-temperature strength due to addition of Mo and is used as heat resistant steel. |
| SUS316L | Carbon content is lower than that of SUS316 and the grain boundary corrosivity and weldability are improved. |

Change in static torsional stiffness due to temperature
This is a value under the condition where the static torsional stiffness at 20°C is 100%.
The change of XSTS,XWSS in torsional stiffness due to temperature is small and the change in responsiveness is extremely small. However, if the unit is used at higher temperature, be careful about misalignment due to elongation or deflection of the shaft associated with thermal expansion.
