Maintenance-free without lubrication! This is a bearing reinforced with epoxy resin and glass fibers. The PTFE liner in the sliding part does not require lubrication.
■ High strength: Usable for applications with maximum surface pressure of 206.9 MPa (30,000 psi) under dynamic loads. ■ Weight reduction: Composite bearing materials (glass fiber and epoxy resin) reduce weight by 77% compared to steel bearings and by 30% compared to aluminum bearings. ■ Low friction and low wear: The self-lubricating liner, woven from high-strength Teflon fibers and polyester fibers, achieves a low friction coefficient (.21 to .05). ■ Non-metallic: Composite bearing materials excel in corrosion resistance, insulation, and chemical resistance. ■ Maintenance-free due to no lubrication: Significantly reduces machine downtime and maintenance costs. ■ Expertise: Holds 16 valid patents, with over 4,200 special designs developed by Duralon, and is flexible in custom solutions. ■ Quick response for prototypes: Lead time for custom products is 6-8 weeks after order, while lead time for standard small orders is 3-4 weeks. ■ Over 40 years of proven use in industrial applications such as construction machinery, agricultural machinery, and food machinery. For the resinization of metal bearings and the strengthening of resin bushes, trust Duralon bearings regardless of the application.
