Polypac Load Bearing Ring Solutions

Load Bearing Ring Solutions by Polypac

Precision Manufacturing

Polypac produces Load Bearing Ring components in a modern, 10,000+ m² facility with 8,000 m² of dedicated production space. Founded in 2008, we began with filled PTFE seals and have grown into one of China’s largest seal manufacturers. Our advanced production and testing equipment ensure each load bearing ring meets tight tolerances and consistent surface finish for demanding hydraulic and mechanical systems.

Materials & Performance

We supply Load Bearing Ring designs in a wide range of materials to match application needs: bronze-, carbon-, graphite-, MoS₂- and glass-filled PTFE for low friction and high wear resistance; elastomers including NBR, FKM, EPDM, silicone and high-performance FFKM for sealing resilience. Material selection focuses on temperature range, chemical compatibility, low friction and load-carrying capability to maximize service life.

Custom Design for Special Conditions

Polypac specializes in customized Load Bearing Ring shapes, sizes and compounds to solve special working conditions—high pressure, abrasive media, or extreme temperatures. Our engineers collaborate with customers to tailor cross-sections, hardness gradients and composite constructions to minimize extrusion, reduce heat build-up and maintain sealing under axial and radial loads.

Testing & Quality Assurance

Every Load Bearing Ring undergoes rigorous testing: dimensional inspection, wear and friction testing, accelerated life cycles and chemical compatibility checks. We maintain long-term cooperation with universities and research institutions to keep our testing protocols and materials science at the forefront of industry standards, ensuring reliability for OEM and aftermarket customers.

Applications & Benefits

Typical applications include hydraulic cylinders, pumps, valves, compressors and heavy machinery where load-bearing sealing elements reduce metal-to-metal contact and extend maintenance intervals. Customers benefit from improved uptime, lower heat generation and predictable performance under continuous load.
