Section 5 :HN Series Hydraulic Nut

1. Screw the hydraulic nut onto the top of the bolt.
2. Apply hydraulic pressure to lift the piston and stretch the bolt.
3. Tighten the locking ring against the nut body, then release pressure to finish.
1.Torque-free design eliminates friction and bolt distortion, applying pure axial tension to bolts
2.Equipped with stroke indicator for monitoring, measuring and controlling stroke during operation
3.Ideal for narrow spaces and heavy-duty vibrating machinery; supports simultaneous multi-bolt assembly
4.Accurate preload setting with precision up to ±3%
