UltraGear has been a leader in the South African gear manufacturing industry since 1993. Over three decades, the company has built its reputation on precision, innovation, and engineering excellence. When it comes to spiral bevel gears, UltraGear has distinct advantages that set it apart from other manufacturers.
1. World-Class Manufacturing Capabilities
UltraGear operates from a state-of-the-art facility equipped with advanced CNC lathes, 5-axis milling machines, horizontal boring mills, and heavy-duty lifting equipment. This allows the company to produce spiral bevel gears of exceptional accuracy and quality. Their facility can manufacture spiral bevel gears up to 2 meters in diameter, making them one of the few companies in South Africa with this level of capacity.
2. Precision Engineering to Global Standards
All gears are designed and manufactured to meet DIN and AGMA specifications, ensuring that UltraGear products align with the highest international standards. This commitment to global quality benchmarks means Ultra Gear’s spiral bevel gears can perform reliably in even the most demanding applications.
3. Expertise in Customisation and Reverse Engineering
One of UltraGear’s greatest strengths is its ability to offer tailor-made solutions. Through reverse engineering and advanced design software like SOLIDWORKS and GEARTRAX, the company can recreate or improve existing gear systems. This is particularly valuable for industries needing replacement parts for legacy equipment or requiring gear systems designed for unique applications.
4. Rigorous Quality Control
UltraGear enforces a strict quality assurance system throughout its manufacturing and assembly process. Every spiral bevel gear undergoes inspections such as 3D scanning, ultrasonic testing (UTI), and magnetic particle inspection (MPI) to ensure structural integrity and dimensional accuracy. This rigorous approach guarantees that every gear leaving the facility is reliable, durable, and fit for purpose.
5, Proven Track Record in Heavy Industry
With over 30 years of service, UltraGear has supplied critical components to South Africa’s mining, engineering, and manufacturing sectors. Their spiral bevel gears are trusted in applications where downtime is not an option, such as large-scale mills, mining conveyors, and industrial gearboxes. Their ability to produce large, heavy-duty gears gives them an unmatched advantage in serving industries that operate on a massive scale.
6. End-to-End Support and Services
UltraGear is not just a manufacturer but a complete engineering partner. Alongside producing spiral bevel gears, they provide:
- Gearbox refurbishment and overhauls
- Condition monitoring and field services
- Crusher refurbishment
- Fabrication of power transmission components
This means customers benefit from a one-stop solution—from gear design and manufacturing to maintenance and lifecycle support.
