What Makes the GR Series Helical Gear Reduction Motor Suitable for Lifting, Metallurgy and Logistics Equipment?

CHANGZHOU, Jiangsu, China, October 15, 2026 – Changzhou Jinao Roller Machinery Co., Ltd., a manufacturer established in 2005 and best known for high-precision industrial rollers, is drawing attention to the GR Series Helical Gear Reduction Motor from its G Series Gear Reducer Motors range. The series covers a power range of 0.12 to 160 kW and a gear ratio range of 1.3 to 26995, which lets it serve light-duty conveying tasks as well as heavy lifting and material handling equipment.

Alongside its roller business, Jinao Roller supplies reducer motors that drive the machines its customers run every day. The GR Series is a helical gear reduction motor built around a modular design, a compact high-strength housing and high transmission efficiency.

What Are the Key Features of the GR Series Helical Gear Reduction Motor?

• Highly modular design: the series is compatible with various power inputs, and the same model can be matched with motors of different power ratings, so combining and connecting units is convenient.
• Wide and precise transmission ratio range: combined models can reach extremely large reduction ratios and very low output speeds.
• Flexible installation: there is no limitation on installation position.
• High strength in a compact size: the housing is high-strength cast iron, and the gears and shafts are gas carburized, quenched and precision ground, giving strong load-bearing capacity per unit volume.
• Long service life: with proper selection and maintenance, the main components, excluding wear parts, have a lifespan of no less than 20,000 hours.
• Low noise: precision machining and careful assembly keep operation quiet.
• High load capacity: the unit can withstand large radial loads.
• High efficiency: transmission efficiency exceeds 96.5% for single-stage, 93% for two-stage and 90% for three-stage configurations.

Why Do Efficiency and Build Quality Matter?

A gear reduction motor runs for long hours, so small differences in efficiency and durability add up. Transmission efficiency above 96.5% in a single-stage configuration means less input power is lost in the gearing, and the figures stay at 93% and 90% for two-stage and three-stage layouts that need larger reduction. The gas-carburized, quenched and precision-ground gears and shafts, together with the cast iron housing, are what allow the unit to carry heavy loads in a compact body and to handle large radial loads at the output shaft.

The modular layout also simplifies planning for engineers and buyers. Because one model can be paired with motors of different power ratings, and because there is no restriction on mounting position, the same series can be fitted to different machine layouts without redesigning the base structure.

Which Industries Use the GR Series?

The GR Series is widely used in lifting, metallurgy, mining, logistics, chemical, construction, textile, energy, pharmaceutical and environmental protection industries. Typical examples include:

• Lifting: driving crane traveling mechanisms.
• Metallurgy: assisting material transport and processing.
• Logistics: driving automatic sorting equipment.

How Does Jinao Roller Support Reducer Motor Buyers?

Jinao Roller integrates research and development, manufacturing, refurbishment and application services, and operates its own machining factory and electroplating plant. Its engineering team offers professional technical consulting on selection and line optimization, and supports customers with installation manuals and real-time remote video guidance during commissioning. Buyers who already know their power, speed and mounting requirements can send them to the company for a matching recommendation and quotation.
