Sew-Eurodrive is providing external oil-cooling and supply systems for heavy-industry gearing (HIG) with lead times as short as six weeks. Built and configured at Sew-Eurodrive’s HIG facility in Wellford, S.C., these systems are engineered to support today’s torque-dense gearboxes, in which thermal limitations often determine gearbox size. Previously available only through global, longer-lead channels, Sew-Eurodrive reports they’re now stocked and assembled in the U.S., eliminating delivery bottlenecks.
As HIG drive systems grow more compact and power-dense, thermal management becomes essential. Sew-Eurodrive’s external lubrication systems address that challenge with configurations that ensure oil is delivered, circulated, and cooled exactly as each application demands. Available types include:
- Oil-to-air cooling systems (OAP1),
- Oil-to-water cooling systems (OWP1), and
- Pressure lubrication systems without cooling (ONP1).
Each type is sized using Sew-Eurodrive’s thermal validation tools, and can be gearbox-mounted or skid-mounted for flexibility in layout and maintenance access.
Designed to support thicker startup oil viscosities up to 5,000 cSt, Sew-Eurodrive’s oil-cooling and supply systems can be tailored to specific requirements, and include modular, sensor-ready features to support system reliability and monitoring. Standard stocked options include:
- Duplex oil filters (25µm) that allow filter change during operation,
- Electro-optical contamination pop-up indicator,
- Oil manometer gauge,
- Oil thermometer gauge,
- Oil pressure switch, and
- Oil temperature switch that monitors the gearbox oil sump in real time
“With local assembly and standard stocked components, we can now deliver complete external thermal management solutions in six weeks, helping our customers get their HIG systems up and running faster and more reliably,” says Austin Burdette, product manager at Sew-Eurodrive HIG USA.
