ZDY Single-Stage Hard Tooth Surface Cylindrical Gear Reducer: Models & Specifications
H1: ZDY Series Single-Stage Gear Reducer — Complete Model and Specification Guide
When an application requires minimal speed reduction with maximum efficiency, the ZDY series single-stage cylindrical gear reducer is the optimal solution. Manufactured to JB/T 8853 standards, the ZDY is the foundational model in the hard tooth surface gearbox family. This guide provides a detailed breakdown of its models, frame sizes, and technical specifications
H2: ZDY SeriesGear Speed Reducer Overview
The ZDY series features a single pair of hardened, ground helical gears. This design minimizes energy loss, achieving transmission efficiencies typically exceeding 98%. It is characterized by a compact structure, low weight, and smooth operation, making it ideal for high-speed drive systems.

The ZDY series covers nominal center distances from 80 mm to 500 mm, with nominal transmission ratios ranging from 1.25 to 6.3. Below is the model and specification breakdown:
| Model / Frame Size | Nominal Center Distance (mm) | Nominal Ratio Range (i) | Nominal Input Power Range (kW)* |
|---|---|---|---|
| ZDY 80 – 160 | 80, 100, 125, 160 | 1.25 – 6.3 | 1.5 – 50 |
| ZDY 180 – 280 | 180, 200, 224, 250, 280 | 1.25 – 6.3 | 40 – 250 |
| ZDY 315 – 400 | 315, 355, 400 | 1.25 – 6.3 | 200 – 800 |
| ZDY 450 – 500 | 450, 500 | 1.25 – 6.3 | 750 – 1500+ |
Ultra-High Efficiency: Single-stage gearing reduces frictional losses to a minimum.
Hardened Gearing: Carburized and ground gears (HRC 54-62) ensure long service life.
Bidirectional Operation: Suitable for both clockwise and counter-clockwise rotation.
Nine Mounting Configurations: Flexible assembly types (I-IX) to fit various plant layouts.
H2: Typical Applications for ZDY
Because of its high-speed output characteristics, the ZDY is widely used in:
High-capacity centrifugal pumps and fans.
Light-duty conveyor drives where high speed is maintained.
Chemical and processing equipment requiring low reduction ratios.
