GBC-NRV-VS Dual Solid Shaft Input Worm Gearbox

✅ Dual Input Shaft Extension (VS)

Both ends of the worm shaft extend outside the housing, enabling hand-crank manual overrides, encoder feedback, or cascade coupling of multiple gearbox stages in a single drive train.

✅ Rapid Stop — 2 to 5 Seconds

Compared with 5–10 seconds for conventional reducers, the GBC-NRV-VS achieves full stop in as little as 2 seconds, enhancing machine safety and cycle-time efficiency.

✅ IP55 Dust & Moisture Protection

Grade IP55 sealing provides excellent isolation against dust and moisture, making it suitable for food processing, outdoor, and washdown environments.

✅ Excellent Thermal Conductivity

Integrated cooling ribs on the housing maximise heat transfer, keeping operating temperatures low and extending lubricant and bearing life.

✅ Self-Locking Worm Drive

Natural self-locking at higher ratios eliminates the need for additional braking devices, reducing system cost and installation complexity.

✅ Enclosed Transmission Structure

No exposed chains, belts, or sprockets — reducing operator injury risk and meeting strict industrial safety standards.

✅ Flexible Output Options

Choose from keyed hollow shaft, output flange, or plug-in solid shaft to match your existing machine design.

✅ Long Service Life

Smooth, low-noise operation suitable for long-term continuous work in harsh industrial environments.
