Industrial gearbox engineering · South Africa
Engineers Gears is built on a singular focus, and that is to specialise exclusively in expert refurbishments, design and manufacturing of industrial gearboxes and power transmission products for low to high torque application requirements.
End-to-end capability
From first inspection to final test certification, we combine practical field experience, first-principles design and precision manufacturing in one accountable workflow.
Capability 01
Structured preventative and breakdown support that restores reliability, extends asset life and gives your team full visibility of the work performed.
A service-ready unit, backed by documented inspection, repair and test evidence.
Support across the asset lifecycle
Engineering support continues beyond manufacture and refurbishment, from replacing obsolete assets to commissioning, monitoring and building your maintenance team’s capability.
Procure direct replacement gearboxes for obsolete units without redesigning surrounding plant. We replicate external dimensions, shaft positions, mounting points and interfaces for seamless integration.
Obsolete unit · existing envelope · direct fitField service engineers provide on-site installation and commissioning expertise, verify alignment and operating conditions, and help confirm that the drive system is ready to enter service.
Installed and verified on siteContinuous monitoring of temperature, vibration and oil condition provides practical insight into gearbox health, supports proactive maintenance and makes developing problems visible earlier.

At our facility or yoursA controlled refurbishment journey
Explore the eight-stage workflow. Each stage creates a clear decision, quality or customer-approval point.
Current stage
We review the order, operating context and available information to confirm the refurbishment scope and priorities.
Design for performance endurance
Every component we produce or refurbish passes through a deliberate design and validation phase. Creo supports product development, while KISSsoft is used for gear analysis and simulation against relevant ISO and AGMA design standards.
Precision capacity
Our Benoni facility brings critical high-accuracy processes closer together to strengthen control, precision and turnaround.
CNC turning for robust, high-accuracy rotational components with exceptional surface finishes, tight tolerances, and reliable repeatability across demanding production environments.
Five-axis and mill-turn machining with Siemens Sinumerik ONE; suited to housings, shafts and complex gears at ±0.01 mm or better.
Gear grinding to 800 mm diameter and module 20, with DIN 3–4 / AGMA 12–13 accuracy and controlled micro-geometry.
800 × 600 × 510 mm travel, workpieces up to 3,000 kg and tapers to 30° for intricate profiles and specialist tooling.
Testing, evidence, confidence
Client engineering representatives are invited to observe critical testing and validation before final release.

Safety, health, environment and quality
We comply with applicable legal requirements, statutory obligations, industry standards and recognised HSE practices while protecting employees, clients, stakeholders and the environment.
Prevent or minimise work-related injuries and health impairment through continual improvement, with zero harm as our aim.
Provide effective environmental leadership while recognising that responsible environmental management belongs to everyone working with and for us.
Provide exceptional, high-quality client services and conduct business professionally and efficiently.
Build workforce competence and responsibility through careful selection, retention, education, training and awareness.
Identify, assess and prioritise the hazards, risks and opportunities associated with our processes and activities.
