Part No. 16089.HD
The Norbar HT-2/25 AWUR is part of the HandTorque Standard Series and is designed for industrial bolting applications requiring high output torque from a compatible torque wrench. Its multi-stage epicyclic gearbox converts input torque into a much higher output, making it suitable for maintenance, assembly and heavy-duty tightening tasks.
The nominal torque multiplication ratio is 25:1, and the listed working range is 170–1,700 N·m. Norbar specifies the true torque multiplication ratio, so confirm the exact mean torque ratio before calculating input settings for critical joints.
This model accepts a 1/2" square-drive torque wrench and drives a 1" square-drive socket. Its manual operation makes it suitable for remote sites and locations where pneumatic or powered tools are impractical.
The anti-wind-up ratchet helps control stored energy in the gear train and reduces the risk of the input wrench kicking back when released. Follow the manufacturer's operating instructions for correct reaction-arm positioning and controlled release.
If your application requires a smaller output drive, compare this model with the Norbar HT-2/25 AWUR (3/4" output) and confirm the appropriate configuration before ordering.
