Breaking through metal limitations! Shandong Juyuan Plastic Micro Bearings are made of medical grade POM/PEEK composite material and injection molded into one. Weighing only 1/5 of steel bearings, it has excellent corrosion resistance. The dimensions cover an inner diameter of 0.8-20mm, an outer diameter of 2-35mm, and a thickness of 0.8-8mm. The precision grade (ABEC-5) has a radial runout of ± 0.005mm, making it perfectly suitable for high cleanliness scenarios such as semiconductor wafer transfer and medical equipment.
Core Highlights
- Self lubricating worry free: The material contains nano PTFE particles with a friction coefficient as low as 0.08. It can run oil-free for 10000 hours without wear, eliminating lubrication pollution. It is an ideal choice for food packaging machinery.
- Strong corrosion resistance: PP material is resistant to 30% acid and alkali (such as CuCl ₂, NaOH), PTFE coated bearings are resistant to high temperature organic solvents at 120 ℃, and the lifespan is three times that of non-metallic bearings.
- Insulation prevention: The overall insulation resistance is greater than 10 Ω, anti-static, and certified with UL 94 V-0 flame retardant to ensure the safety of high-frequency components in electronic devices.
- Cost effectiveness: Bulk purchase of plastic micro bearings is 40% -50% cheaper than metal bearings, and non-standard customization (flange edges, stop slots, etc.) can be delivered in just 7 working days.
