Introduction to DALON Filament Wound Plastic Bushing

Introducing the pinnacle of advanced bushing technology, DALON's filament wound plastic bushing sets new standards in durability, performance, and efficiency. Our plastic bushings are meticulously engineered, combining the resilience of fiber glass with the unmatched smoothness of PTFE, all encapsulated within a robust composite structure.
Innovative Construction for Unrivaled Performance:
- At the heart of our plastic bushing lies the inner lining, a sophisticated blend where PTFE fibers intertwine with special high-strength fibers to create a sliding layer that boasts exceptional lubricity and wear resistance. This innovative design ensures seamless motion, reducing friction and enhancing the longevity of both the bushing and the counterpart surfaces. Encasing this sliding paradise is the outer lining, crafted from polymer fiber reinforced with high-temperature and high-strength epoxy resin. This load-bearing layer is not just a shell but a fortress, offering unparalleled support and resistance to environmental challenges, including high temperatures and mechanical stresses.
Versatile Offerings for Diverse Applications:
- DALON's wound fiber glass composite bushings are not limited to standard shapes. Our catalog spans bushings, plates, discs, and specialized forms, designed to cater to a wide array of industrial needs. Whether your application demands unique geometries or specific performance criteria, DALON is equipped to deliver solutions that fit seamlessly into your operations.
Self-Lubricating and Maintenance-Free:
- Our composite plastic bushing emerges as a beacon of innovation in the realm of non-metal self-lubricating shaft sleeves. The continuous winding of PTFE and high-strength fiber creates an inner sliding layer that eradicates the need for external lubrication. Backed by a polymer fiber reinforced epoxy resin layer, our bushings assure high-temperature resilience and strength, setting a benchmark for maintenance-free operation.
In essence, DALON's filament wound plastic bushing represents the future of friction management technology. It embodies a perfect harmony between advanced materials and cutting-edge manufacturing, offering a solution that is not only sustainable but also elevates the operational efficiency of a wide spectrum of applications. Choose DALON for a bushing experience that transcends traditional limitations, ensuring your machinery operates at its peak, uninterrupted and efficient.
