ITH Type MS
A multi-stage hydraulic bolt tensioning cylinder for radially confined spaces, covering bolt quality 10.9 from M16 to M110, with automatic piston return.
More Information
The ITH Type MS is a multi-stage bolt tensioning cylinder with multiple piston surfaces and automatic piston return, built for high bolting cycles. Its tall, slim design suits applications with limited radial clearance but open vertical space, making it well suited to turbines, engines, and other compact machinery. As standard, it’s designed for bolt quality 10.9 across M16 to M110, with other qualities and custom dimensions available on request.
Key Features
- Multi-stage piston design generates high preload force in radially confined spaces.
- Automatic piston return speeds up cycling between bolts.
- Patented safety architecture, including a cycle counter and safety handle, supports reliable operation.
- Compatible with hexagon nuts, round nuts, and ITH RMS/RMZ and IHF round nut designs.
- Custom bolt qualities and dimensions available on request for non-standard applications.
Typical Applications
- Turbine and power plant construction
- Wind energy installations
- Gas and diesel engine construction
- Heavy machinery and crushers
- General construction projects with radially confined bolting access
