Mainly used for 10.9 grade high-strength bolts.

High operating pressure: 150MPa.

The design of an automatic fast return mechanism greatly reduces labor intensity.

Note: The bolt tensioner shown in the table above is designed for disassembling high-strength 10.9 grade bolts and is based on 90% of the elongation limit of 0.2; If higher tensile force is required, use the next larger cylinder with the same thread size adjacent to the bolt tension head in the table (for example, for M42, MSD45 is used instead of MSD42), or perform special design. The above single-stage tensioners are a small part of our company's products. More than 90% of tensioners require special design according to working conditions. We have years of mature design and on-site experience, and can customize products suitable for your working conditions; Please contact our company for details.
