High Mechanical Efficiency – With an exceptional efficiency rating of 98%, this gear unit minimizes energy loss and ensures optimal power transmission, making it ideal for continuous-duty operations in energy-sensitive environments.

Single-Stage Helical Gear System – The 1-stage gear design enables compact installation while delivering accurate torque transfer and minimal backlash, contributing to precision in motion control and automation systems.

Ratio 3.38:1 – A medium-low gear reduction ratio that provides a balanced speed-to-torque conversion, well-suited for servo-control applications, belt conveyors, and packaging lines requiring moderate torque amplification without excessive speed loss.

Aluminium Housing – The lightweight yet durable aluminium construction ensures excellent thermal dissipation, corrosion resistance, and weight reduction, ideal for mobile systems or installations where mass constraints are a factor, such as in robotics and compact machinery frameworks.

Input Shaft Diameter: 11 mm – Compatible with standard B14 motor shafts, providing straightforward integration in modular motorized systems, reducing downtime during assembly and increasing configurability.

Output Shaft Diameter: 14 mm – Offers compatibility with a wide range of couplings, pulleys, and load systems, facilitating versatility for use in mechanical drives, agitating systems, and process control installations.

B14 Flange Interface (Input 63B14, Output 71B14) – Enables direct interface with IEC-standard motors, allowing fast motor substitutions, simplifying stock management for OEMs, and enhancing drive system upgradeability.

Size Class: 211A – Optimized footprint for machinery with limited space, enabling installation in automation cabinets, machine frames, and tight enclosures without compromising strength or performance.

Input/Output BCD (Bolt Circle Diameters): 75 mm input / 85 mm output – Aids in secure mechanical mounting and alignment, reducing vibrations in dynamically loaded systems and improving durability in high-duty cycles.
Application Areas:
• Conveying Systems – Ideal for driving rollers or belts in horizontal or inclined transport lines in logistics, automotive assembly, or airport baggage handling.

• Packaging Machinery – Enables accurate motion control for indexing, sealing, or feeding systems where compactness and high efficiency are critical.

• Robotics & Mechatronics – Provides reliable reduction for axis control and actuator modules in robot arms, pick-and-place systems, and collaborative workspaces.

• Process Automation – Applicable in mixers, dosing pumps, and rotating assemblies in chemical, food, or pharmaceutical industries where smooth motion is essential.

• Agricultural & Mobile Equipment – Suitable for light-duty hydraulic drives or electric drive systems where space, weight, and corrosion resistance are key.
