Key Features
- High Transmission Efficiency: Engineered for minimal power loss; single-stage gear unit can reach up to 96% efficiency.
- Modular Design: Flexible modular system for easy combination with various motors and power inputs.
- Wide & Fine-Graded Ratio Range: Broad spectrum of finely stepped transmission ratios; combined models can achieve very large ratios.
- Versatile Mounting Options: Suitable for multiple installation positions, including horizontal (foot-mounted) and flange-mounted layouts.
- Durable & Compact: High-quality materials with a compact design for long service life in demanding conditions.
Design and Mounting Options
The R Series comes in several design versions to suit your mounting requirements:
- R..D..: Foot-mounted helical gear motor.
- RF..D..: Flange-mounted helical gear motor.
- R..F..D..: Foot-and-flange-mounted helical gear motor.
- RM..D..: Flange-mounted helical gear motor with extended bearing housing for higher overhung loads.
- RX..D..: Single-stage, foot-mounted helical gear motor.
- RXF..D..: Single-stage, flange-mounted helical gear motor.

Engineering Data and Selection Verification
Use the information on this R Series Transmission Industrial Helical Gearbox with Motor page for preliminary comparison. Final dimensions, materials, interfaces and operating limits must be confirmed against the current manufacturer catalog or an approved project drawing before purchase, fabrication or installation.
Table scope: each parameter row applies only to the model or size identified in that row. Do not interpolate, combine or transfer values between sizes without manufacturer confirmation.
Required Project Inputs
- Input speed and motor information
- Required output speed or target ratio
- Driven load type, start-stop pattern and operating schedule
- Mounting position, shaft direction and available installation space
- Site environment and maintenance-access requirements
Interfaces to Confirm
- Model size and mounting-hole pattern
- Input and output shaft or bore dimensions
- Flange, keyway, coupling and guarding arrangement
- Shaft center position and surrounding clearance
- Lubrication and inspection access
Reproducible Speed and Ratio Check
Required ratio: input speed ÷ target output speed. Expected output speed: input speed ÷ selected ratio. Record the source of each input value and use consistent units.
This arithmetic check does not confirm torque, power, service factor, temperature, efficiency or life. Ask ZPGear to verify those items from the current manufacturer data for the selected model and operating condition.
Source record: keep the manufacturer name, catalog or drawing number, revision date, selected model size, project inputs and final approval sheet with the order documentation. Send the project information to ZPGear for confirmation.
