Heavy Duty Loaded Rod U-Cup Seal With Active Backup Ring
Series 163: Heavy Duty Loaded Rod U-Cup Seal With Active Backup Ring
The 163 series is a heavy duty polyurethane seal with multiple features that include a double-lipped U-cup design, an internal O-Ring energizer and a reinforced backup ring on the heel. This seal is ideal for applications where high-pressure spikes are like to be encountered. This seal also features additional sealing contact points in the groove.
Installation
Benefits
High-pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
Applications
The 163 series rod seal is typically used in heavy-duty applications, where pressure spike and large extrusion gaps exist.
Typical applications include:
- Mining
- Mobile Hydraulics
- Hydraulic Cylinder Rebuild
- Agricultural Hydraulics
- Construction Equipment
The 163 series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, NBR O-ring and polyacetal backup ring. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
