 Hydraulic Bolt Tensioners KTS

Bolted assemblies and couplings are the most widely used connection systems in industry. To ensure the optimum reliability of your installations it is essential to obtain precise and uniform tightening of all the bolts. Indeed, 30% of assembly failures are caused by defective or irregular tightening. On the strength of its experience in the area of hydraulic tightening, Kacharabzar has developed a broad range of hydraulic bolt tensioners,both standard and customized

Main advantages KTS

• Accuracy and control: tightening preload can be adjusted within one bar

• Uniformity: identical force applied to all the tensioners

• Simplicity and speed: as many tensioners as there are bolts to be tightened can be utilized

• Integrity of the parts preserved

• Cost reduction in use, inspection and maintenance

• Safety and reliability: ideal for critical applications

• Adaptability: all types of material such as steel, stainless steel, titanium, etc.

The KTS tensioner is specially designed to tighten small bolts (starting with M8). However, it can also tighten large bolts. Its design also tolerates possible geometric faults in the assembly parts.

Reference examples:

• Reference example for a complete tensioner for M12 bolts: KTS 9 M12 ¥ 1,75

• Reference example of hydraulic body for the KTS 9 tensioner: HTS 9 C (M48 ¥ 5 much too big !!!)
