Product Description

BPG/BPGA Precision Planetary Gear Units – High‑Torque, Low‑Backlash Solutions for Automation

Raydafon Group presents the BPG and BPGA series – a premium range of precision planetary gear units engineered for industrial automation, robotics, and high‑performance machinery. Featuring case‑hardened and ground planetary gears, robust output shafts, and minimal backlash, these gear units deliver exceptional torque density, smooth operation, and long service life. Available in multiple frame sizes and ratios, the BPG/BPGA series offers flexible mounting options and is fully customizable to meet your specific application requirements.

Key Advantages at a Glance

High Torque Density: Compact design delivers outstanding torque output in a small footprint.
Low Backlash: Precision‑ground gears ensure minimal angular play for accurate positioning.
High Efficiency: Planetary gearing achieves up to 97% efficiency, reducing energy losses.
Robust Construction: Hardened and ground gears, rigid housings, and high‑capacity bearings.
Versatile Mounting: Flange, shaft, and foot mounting options available.
Custom OEM Solutions: Ratios, shafts, and interfaces tailored to your equipment.

Precision Ground GearsCase‑hardened and ground planetary gears ensure low backlash (< 3 arcmin) and high torsional stiffness for accurate motion control.

High Torque CapacityOptimised gear geometry and high‑strength materials allow for peak torques up to several thousand Nm, depending on size.

Low Noise & VibrationPrecision tooth profiles and balanced rotating parts minimise noise and vibration, ideal for quiet environments.

Wide Ratio RangeAvailable in single‑stage (3:1 – 10:1) and two‑stage (15:1 – 100:1) configurations to suit diverse speed/torque requirements.

Flexible IntegrationDesigned with standard IEC motor flanges and hollow/solid output shafts for easy coupling to servo or stepper motors.

Durable & ReliableFilled with high‑grade lubricant and sealed against contamination – maintenance‑free for extended periods.

Frequently Asked Questions

Q: What is the difference between BPG and BPGA?

A: BPG models feature a solid output shaft, while BPGA models have an output flange for direct coupling to driven equipment. Both offer the same performance and customisation options.

Q: What is the typical backlash for standard units?

A: Standard backlash is < 3 arcmin for single‑stage and < 5 arcmin for two‑stage units. Ultra‑precision versions with < 1 arcmin are available on request.

Q: Can I use these gear units with servo motors?

A: Yes, they are designed with standard motor mounting flanges and hollow input shafts for direct coupling to servo or stepper motors.

Q: What is the maximum input speed?

A: Standard input speeds up to 6000 rpm are supported; higher speeds available for specific applications.

Q: What is the warranty period?

A: We offer an 18‑month warranty from date of shipment, covering manufacturing defects, with full technical support.
