Custom Flexible Drive Shafts for Heavy-Duty Road Machinery
Phidix’s custom-engineered flexible drive shafts are built for the demands of road construction equipment, combining precise motion control with superior durability. These assemblies enable smooth push-pull force transmission in tight, vibration-heavy environments, ensuring reliable performance across multiple machine systems—from vibratory rollers to milling heads.
Why Choose Phidix Flexible Shafts?
| Feature | Benefit |
| High flexibility | Adapts to tighter bend radii and variable routing angles |
| Strong force transmission | Minimal motion loss under heavy load conditions |
| Reinforced construction | Withstands shock, vibration, and repeated cycling |
| Corrosion & wear resistance | Stainless steel end fittings + multi-seal protection |
| Maintenance-friendly | Easy to install, inspect, and replace in the field |
These shafts are ideal where precision control meets mechanical stress—helping engineers simplify routing, reduce rigid linkage points, and increase equipment reliability.
Built for Road Equipment Systems
Our flexible shafts are field-proven in:
• Vibratory rollers – for screed and compactor control
• Asphalt pavers – driving auger feed or flow adjustment
• Road milling machines – transmitting rotation to cutter drums
• Wheel loaders – supporting steering or bucket actuation
• Excavators – enabling boom, arm, or attachment control
Conduit & Core Configuration
We offer multiple conduit and cable core options tailored to your equipment layout:
• Reinforced braided conduit – for general industrial use
• Long lay core + shuttle-mold fittings – for smoother cable actuation
• Polypropylene jacket – stiffer routing in fixed paths
• Nylon sheath – flexible and heat-resistant for hot engine compartments
Recommended clearance between conduit I.D. and core O.D. is 0.015–0.025" for push-pull setups. Contact us for specific application engineering.
Available Models
Phidix offers multiple standard flexible shaft models under the heavy-duty road machinery series. While all models share the same construction, materials, and performance characteristics, they vary in stroke length and overall dimensions to suit specific installation constraints.
| Model Number | Stroke Length | Input Load (Working / Max) | Application Example |
| SUVL-BSP-TT-100-2035 | 150 mm | 250–450 lbs / 300–500 lbs | Compact loader & roller systems |
| SUL-TG-150-3780 | 300 mm | 300–600 lbs / 400–600 lbs | Excavator boom or paver feeder |
| SU-VL-TT-70-1200 | 70 mm | 210–400 lbs / 300–500 lbs | Asphalt auger or steering controls |
→All models feature a PVC conduit with carbon steel core, green finish, and support lengths up to 10 meters. Fittings and lengths can be customized upon request.
