Sew Eurodrive now offers external oil cooling and supply systems for heavy industry gearing, with lead times of about six weeks. Built and configured at Sew Eurodrive Heavy Industry Gearing (HIG) in Wellford, South Carolina, these systems are designed for use with high-torque gearboxes, where heat management can influence gearbox size.
Previously available only through longer-lead global channels, these systems are now stocked and assembled in the U.S., reducing delivery times.
Precision cooling for critical applications
As HIG drive systems become more compact and torque-dense, thermal management is required. Sew Eurodrive’s external lubrication systems are designed to deliver, circulate, and cool oil according to application requirements.
Available types include:
- Oil-to-air cooling systems (OAP1)
- Oil-to-water cooling systems (OWP1)
- Pressure lubrication systems without cooling (ONP1)
Each unit is sized using Sew Eurodrive’s thermal validation tools and can be mounted on the gearbox or on a skid, depending on layout and maintenance requirements.
What’s new
- Assembled in the U.S., reducing delivery time from 14–20 weeks to as little as 6 weeks
- Standard options in stock and ready to configure
- Designed to support thicker startup oil viscosities up to 5,000 cSt
Built for application
Sew Eurodrive’s Oil Cooling and Supply Systems are configurable for different application requirements and include modular, sensor-compatible features for system monitoring. Standard stocked options include:
- Duplex oil filters (25µm) — allows filter change during operation
- Electro-optical contamination pop-up indicator
- Oil manometer gauge
- Oil thermometer gauge
- Oil pressure switch
- Oil temperature switch — all to monitor 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.” said Austin Burdette, product manager, Sew Eurodrive HIG USA.
