Double-Acting Lock Nut Cylinders

Menomonee Falls, WI—May 3, 2018—Enerpac, an international market leader in high-pressure hydraulics, has released its new Double-Acting Lock Nut Cylinders with fast hydraulic retract and high side-load capacity.

Enerpac Lock Nut Cylinders provide mechanical load holding for extended periods of time, providing a safer work environment. The lock nut cylinders are designed to withstand up to ten percent side-load of maximum capacity and include an integrated tilt saddle allowing up to five degrees of misalignment.

“The cylinders are weather protected on the inside and out,” said Charlie Kopplin, Director of Marketing – Americas. “The hardened surface resists side-loading and cyclic wear. Another highlight is the bearings that are more durable, yet replaceable.”

Key features include:

  • Certified lifting eyes, base mounting holes and collar thread as standard
  • Stop-ring to prevent plunger blow-out
  • Low-friction lock nut, spin easy that saves time and effort

“Mechanical lock nuts have always been the safest way of holding cylinder position for extended periods of time,” said Kopplin. “Double acting cylinders offer the greatest control during both lifting and lowering of loads. Enerpac has now created a standard offering that combines these two benefits into one design.”

Enerpac’s lock nut cylinders are available in low height, lightweight or high tonnage models, with capacities from 20 to 1,000 tons and stroke lengths from 1.77 to 11.81 inches. The Double-Acting Lock Nut HCRL-Series are available up to 2,000-ton and additional stroke lengths are available upon request.
