Polypac Ball-Head Dust Ring — High-Performance Hydraulic Dust Seals

Ball-Head Dust Ring by Polypac

Polypac's Ball-Head Dust Ring is a purpose-designed dust seal that protects hydraulic rods and bearings from contamination while ensuring smooth reciprocating motion. Leveraging over a decade of sealing expertise and advanced production facilities, Polypac manufactures Ball-Head Dust Rings that meet stringent performance demands for industrial, mobile, and offshore hydraulic systems.

Key Features & Performance

The Ball-Head Dust Ring features a low-friction profile with a resilient lip geometry to reliably exclude dust, dirt, and moisture. Optimized for long stroke life, the design minimizes seal drag and rod wear while maintaining stable contact under side-loads. Typical benefits include reduced maintenance downtime, improved sealing reliability, and extended component life for cylinders and actuators.

Materials & Customization

Available in a wide range of elastomers—NBR, FKM, EPDM, silicone and FFKM—Polypac tailors Ball-Head Dust Ring compounds to specific temperature, chemical and abrasion requirements. For extreme applications we also supply filled PTFE variants (bronze, carbon, MoS₂, graphite, glass) and bespoke blends. Custom sizes, hardnesses, and molded geometries are produced in our 10,000+ m² facility to meet OEM specifications.

Applications & Industry Use

Ideal for hydraulic cylinders, linear actuators, construction machinery, agriculture equipment and marine systems, the Ball-Head Dust Ring excels wherever contamination control is critical. Its geometry and material options make it suitable for harsh environments including high dust, salt spray, and frequent pressure cycling.
