Complete Range of Industrial Gearboxes & Gear Motors

Ubuty manufactures seven gearbox series covering the full range of industrial speed reduction, torque transmission, and mounting configurations. Each series is engineered for specific application requirements — from compact worm gear reducers to high-efficiency helical hypoid drives.

NMRV Series — Worm Gear Reducers & Gear Motors

Manufactured under the KB Transmission Star brand, our NMRV025–150 worm gear reducers provide compact right-angle transmission for conveyor, packaging, automation and general industrial machinery. Standard single-stage ratios range from 7.5:1 to 100:1. → View NMRV Series specifications

TRC Series — Small Helical Gearboxes & Gear Motors

Compact inline helical gearboxes for light-duty automation and precision positioning applications requiring low backlash. → View TRC Series specifications

R Series — Helical Gearboxes & Gear Motors

Standard inline helical gear reducers delivering 94–97% efficiency for continuous-duty conveyor, mixer, and processing equipment drives. → View R Series specifications

K Series — Helical Bevel Gearboxes & Gear Motors

Right-angle helical-bevel gearboxes combining high torque density with 90° shaft configuration — ideal for space-constrained and inclined conveyor applications. → View K Series specifications

S Series — Helical Worm Gearboxes & Gear Motors

Hybrid helical-worm configuration balancing cost efficiency with improved performance over standard worm gearboxes. → View S Series specifications

F Series — Parallel Shaft Helical Gearboxes & Gear Motors

Heavy-duty parallel shaft helical gearboxes for high-torque industrial drive applications including mining, steel, and bulk material handling. → View F Series specifications

KKM Series — Helical Hypoid Gearboxes & Gear Motors

Our KKM Series is designed as a high-efficiency alternative for selected NMRV worm gearbox applications. Depending on the model and configuration, mounting dimensions, ratio, motor interface and output requirements should be verified before replacement. → View KKM Series specifications | → Read: Why Replace NMRV with KKM

Gearbox Manufacturing & Engineering Capabilities

Our manufacturing process combines precision machining, gear production, controlled assembly and systematic inspection to support consistent gearbox quality from prototype through volume production. Precision Machining CNC machining of gearbox housings, shafts and transmission components to controlled dimensional tolerances. Gear Manufacturing Gear hobbing, gear grinding and related machining processes for helical, bevel, worm and hypoid transmission components. Heat Treatment Controlled heat-treatment processes designed to achieve the required hardness, wear resistance and service life of critical transmission components. Assembly & Inspection Controlled gearbox assembly followed by dimensional inspection, rotation checks and final quality verification. Final Testing Finished gearboxes are inspected and tested before shipment according to the applicable product and order requirements. Application Engineering Support for ratio selection, torque calculation, service-factor verification, motor matching, mounting configuration and replacement projects. OEM Manufacturing Custom shafts, mounting configurations, branding, packaging and application-specific gearbox solutions are available for qualified OEM projects.

Quality Control from Components to Final Gearbox

Quality control is integrated throughout our manufacturing process rather than limited to final inspection. Our quality management and inspection procedures cover:

• Incoming material and component inspection
• Gear dimensional and tooth-profile inspection
• Hardness verification
• Shaft and housing dimensional inspection
• Assembly inspection
• Rotation and noise checks
• Final pre-shipment inspection
• Production and inspection record management

Our quality management system is certified to ISO 9001:2015.
