NSD Series

Norbar Square Drive (NSD) hydraulic ratchet wrenches offer a cost efficient option to handle a wide range of bolt tightening and break-out needs.

The NSD Series employs a “patented design” which increases accuracy and reduces the number of moving parts. Our robust and lightweight aluminum body completely encloses the drive train assembly keeping the crucial lubricant inside the tool while significantly reducing the opportunity for outside elements to contaminate the inside of the tool.

The series features nine different tools with capacities ranging from 143 to 54,905 lbf.ft of torque using a 10,000 p.s.i. hydraulic pump.

  • Square drive – for use with all standard size square drive impact sockets. The square drive is easily reversible for the tightening and loosening of threaded fasteners.
  • High strength, lightweight body – made of durable, high strength, lightweight aircraft alloy giving the housing maximum strength with minimum weight.
  • Uni-body – eliminates “pinch points” and reduces side loading. Totally enclosed drive-train assembly reduces the risk of foreign objects obstructing any internal components.

  • Reaction system – this system allows for a 360° reaction rotation that is able to index in increments of 7.5 degrees creating 48 different reaction points in both directions. This reaction system is reversible which provides the user with an additional 48 different reaction points, making 96 reaction points in total.

  • Anti-reverse pawl – holds rotational wind-up forces to maintain required torque.

  • Pawl release – anti-reverse pawl release mechanism allows for manual release of the tool if “binding” occurs.

Use Our Calculators

Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas:

  1. Unit conversion to assist international measurement definitions.
  2. Torque extension for setting correct values
  3. Torque tension to identify precise levels of torque to be applied for individual applications.
