About Us
Early Days
From Garage Beginnings to Industry Leader
In 1997, CJ Bearings & Castings began as a bold, 100% black‑owned venture in the mining supply industry. With limited capital but unwavering determination, we started in a family garage, supplying bearings to local mines.
Quality, fair pricing, and reliable service quickly built trust. Demand grew, and we expanded to Booysens Reserve near Gold Reef City — a central hub for South Africa’s mining industry.
From those humble beginnings, we invested in our first lathes, moved into machining, and built a fully‑fledged workshop. What started small has grown into a respected name in mining solutions.

Today, CJ Bearings & Castings is recognized as a specialist in rolling stock wheels and axles for Southern Africa’s mining industry.
