Heavy-Duty Hydraulic Steering Cylinders for Earthmoving & Commercial Equipment

At TOSOG (The One Stop O.E.M Group), we specialise in the supply, refurbishment, overhaul, and technical support of high-performance hydraulic steering cylinders engineered to deliver exceptional precision, operational safety, and long-term durability in the most demanding working environments. Our steering cylinders are designed to withstand extreme loads, high operating pressures, abrasive conditions, and continuous duty cycles, ensuring smooth and reliable steering performance under all conditions.

Our steering cylinder solutions are widely trusted across earthmoving equipment, yellow plant machinery, mining fleets, agricultural equipment, and heavy commercial vehicles, where steering reliability is critical to machine safety, productivity, and operator control. From articulated dump trucks and wheel loaders to bulldozers, graders, tractors, and heavy trucks, TOSOG steering cylinders are built to perform in harsh African operating conditions, including heat, dust, mud, vibration, and uneven terrain.

We offer a comprehensive range of OEM, high-quality aftermarket, remanufactured, and fully reconditioned steering cylinders, providing flexible solutions to suit both new equipment requirements and cost-effective fleet maintenance strategies. Our reconditioned steering cylinders undergo a complete strip-down and inspection process, including barrel honing, piston rod re-chroming or replacement where required, seal replacement with high-pressure kits, and final pressure and performance testing to ensure compliance with OEM specifications.

Backed by expert technical knowledge, experienced hydraulic specialists, and in-house repair capabilities, TOSOG delivers fast turnaround times, reduced equipment downtime, and dependable steering performance. With nationwide delivery across South Africa and cross-border supply throughout Africa, we ensure our customers receive reliable steering solutions exactly when and where they need them.
