描述
Product Features
Features a torque-free tensioning design, eliminating the effects of friction, bolt twisting, and other factors that can influence bolt preload. The stud is subjected to pure axial tensile force during tightening.
Particularly suitable for confined spaces and heavy-duty vibrating machinery, and supports the simultaneous tightening of multiple bolts.
Provides accurate preload control with precision of up to ±3%.
Equipped with a stroke indicator, allowing the operator to observe, measure, and control bolt elongation during operation.
Tensioning capacity: 198–2,450 kN
Applicable bolt range: M22–M100
Maximum working pressure: 1,500 bar
