Core Product Line · High-Torque Nutrunner & Bolting Ergonomics
Heavy-duty articulated torque reaction arms, parallel pantograph linkages, and overhead KH Track linear torque tubes engineered to absorb 50 Nm to 1,000+ Nm of DC nutrunner reaction torque—eliminating operator wrist and shoulder kickback while floating heavy tightening tools weightlessly.
On automotive chassis, powertrain, and EV battery lines, operators tighten safety-critical joints using heavy DC electric nutrunners, angle tools, and multi-spindle tightening heads ranging from 50 Nm up to 1,000+ Nm. Holding an 8–35 kg tool manually against repeated high-torque shut-off impulses causes severe wrist, elbow, and shoulder injuries—and allows tool tilt that leads to cross-threaded bolts or false torque readings.
Ovity Sdn. Bhd. designs, fabricates, and modifies custom DC Torque Tool Reaction Arms, Zero-Gravity Pneumatic Tool Supports, and EXOARM assistive arms in Puchong, Selangor. Whether mounted on a rigid floor pedestal column with precision leveling plates or suspended from an overhead KH Track rail trolley to follow a moving vehicle conveyor, our arms channel 100% of the reaction torque safely into the structure while keeping the tool completely weightless.
Ovity's 100% pneumatic balancers, air hoists, KH Track rails, and mechanical reaction arms operate reliably in Malaysia's high shop-floor heat and humidity, require zero expensive imported servo drives or PCB boards, and are supported directly by our Puchong engineering and fabrication team.
Every Ovity system is engineered and supported from Puchong, Selangor around your payload (kg), torque (Nm), overhead span, conveyor height, and cycle-time requirements.
