2. Superior Precision Gearing

• Utilizes computer-designed helical gears crafted from strong alloy steels, ensuring outstanding load capacity. Gears are case carburized for extended lifespan, with ground profile teeth featuring a crown tooth profile for optimal engagement. Manufactured to ISO 1328-1997 standards, achieving 98% efficiency per stage for unparalleled smooth and quiet operation with multiple teeth in mesh.

3. Robust Maximum Capacity Housing

• Constructed from close grain cast iron, this gearbox housing boasts exceptional vibration dampening and shock resistance. Precision bored and dwelled components guarantee precise in-line assembly, making it ideal for heavy-duty operations.

4. Durable Alloy Steel Shafts

• Crafted from hardened, strong alloy steel and ground on journals, gear seatings, and extensions to withstand the highest loads and torsional stresses. Features generously sized shaft keys to absorb shock loading, adhering to ISO quality standards for maximum reliability.

5. Innovative Case Support Feet

• Integrated additional case feet eliminate the need for critical torque arm bolt tightening, maintaining the standard torque arm mounting position within recommended limits for enhanced operational stability.

6. Reliable Backstops

• Available as optional parts, our anti-run back devices are compatible with all 13:1 and 20:1 ratio units, ensuring safety and reliability in reversing operations. Not recommended for 5:1 ratio units to maintain system integrity.

7. High-Quality Bearings and Seals

• Features bearings that are proportioned to support heavy loads, conforming to the ISO dimension plan for global availability. Oil seals are equipped with double-lipped garter springs, providing superior oil retention and protection against contaminants.

8. Enhanced Rubberized End Caps

• Self-sealing intermediate cover plates conform to standard ISO housing dimensions, offering additional protection and maintenance ease for demanding environments.

9. Adjustable Torque Arm Assembly

• Designed for effortless adjustment of the belt tension, simplifying installation and maintenance while enhancing system performance and longevity in heavy-duty applications.

Conclusion
This enhanced shaft-mounted gearbox is engineered to meet the rigorous demands of heavy-duty industrial applications, offering unmatched durability, efficiency, and versatility.
