TG Series Hydraulic Bolt Tensioner

This product is a professional tool that uses hydraulic power to accurately stretch bolts to produce controllable preload, and uses gravity reset. The hydraulic system is used to apply axial tension to the bolts to elastically stretch them, and then the position is locked by tightening the nuts, thereby ensuring uniform preload and long-term stability of the bolt connection. It is widely used in high-precision, high-load industrial scenarios.

• Light weight, compact structure, high precision,
• The surface is rust-proof and corrosion-resistant.
• Strong versatility, by replacing the stretching head, it can be applied to multiple specifications of bolts for stretching.
• Spring automatic reset, suitable for frequent use.
• Multiple stretchers can be stretched synchronously
• Rated working pressure is 150MPa, and can be equipped with high-pressure manual pumps, high-pressure pneumatic pumps and high-pressure electric pumps.

Multiple units are connected in sequence to achieve synchronous stretching

Please select the tensioning head that matches the tensioning cylinder. For example, when ordering a tensioner for tensioning M20X2.5 bolts, you can choose:
Tensioning cylinder model: TG1, matching tensioning head model: TG1-M2025. If you also want a tensioning cylinder to be suitable for multiple bolt specifications, please select multiple tensioning heads according to the parameter table.
