Titanus Slew Rings

What Titanus Slew Rings does

Titanus Slew Rings (TSR) is a family-owned South African precision engineering manufacturer founded in 1975 by Renato Casagrande, headquartered at a 30,000 m² site in Elandsfontein, Johannesburg. The company designs, manufactures, and refurbishes slew bearings (ball, roller, and combination types, with and without gearing), gears and sprockets (spur, helical, bevel, worm, rack, sector, and girth gears), hydraulic rotary actuators, slew drives, and provides specialized large-component machining and induction hardening as services. Production runs on a capital-intensive asset base that includes the largest simultaneous 5-axis CNC machining capability in the Southern Hemisphere (DMG Mori DMU 340), the largest CNC vertical turning lathe in South Africa, the largest induction hardening platform in Africa, and a 12,000 m² factory with 50-ton lifting capacity, supported by an off-grid 300 kWh solar installation.

TSR earns revenue primarily through quote-based, project-by-project sales of engineered components and related services to a globally distributed base of OEMs, maintenance engineers, and end-users in mining, metallurgy, energy, maritime, ports, construction, and scientific research. Pricing is not publicly disclosed; transactions are direct and consultative, with the company holding stock of common bearings and slew drives for rapid delivery and offering design assistance, reverse engineering, installation supervision, and long-term refurbishment programs. Notable programs include supply to the SKA/MeerKAT radio telescope, split-bearing replacements at Loy Yang power station in Australia with Schaeffler Australia, and shipment to multinational customers such as FLSmidth, Metso, ArcelorMittal, Komatsu, and Eskom.
