6200 氧化锆 ZRO2 全 10x30x9 毫米陶瓷球轴承

产品概述

Unlike hybrid bearings that combine ceramic balls with steel rings, this is a 100% 全陶瓷轴承. The inner ring, 外圈, and all rolling elements are manufactured entirely from Zirconium Oxide (ZrO₂) . No steel components remain. This all-ceramic construction unlocks a level of environmental tolerance and operational freedom that no metal-based bearing can approach.

主要特点:

• Runs Completely Dry – Zero Lubrication Required
  The most significant advantage of a full ceramic bearing is its ability to operate without any oil or grease. ZrO₂ has inherent self-lubricating properties and a low coefficient of friction. This eliminates lubricant contamination risks in food processing, 制药, and semiconductor applications. It also removes the maintenance burden of greasing schedules—the bearing simply runs, year after year, without intervention.

• Ultimate Corrosion Resistance – Fully Inert to Chemicals
  ZrO₂ is chemically inert in most acids, 碱类, and saline solutions. The only notable exception is hydrofluoric acid (HF). Unlike steel bearings that rust and pit within days of exposure to moisture, 这 6200 ZrO₂ maintains its precise geometry and smooth surface indefinitely in wet, salty, or chemically aggressive environments. This makes it ideal for chemical pumps, 船舶设备, desalination plants, and food processing washdown areas.

• Electrically Insulating – Eliminates Arcing Damage
  ZrO₂ is a complete electrical insulator. In variable frequency drive (变频驱动) 电机, 发电机, and any equipment where stray currents pass through the bearing, steel bearings suffer catastrophic arcing damage (fluting). 这 6200 ZrO₂ eliminates this failure mode entirely, making it essential for modern electric motors and generators.

• Non-Magnetic – Safe for Sensitive Instrumentation
  Unlike steel bearings that retain residual magnetism and attract metallic debris, ZrO₂ is completely non-magnetic. This is critical for MRI machines, 粒子加速器, 电子显微镜, and any precision instrumentation where magnetic fields must be strictly controlled.

• Available with PTFE Seals and PEEK Cage
  For enhanced protection, 这 6200 ZrO₂ is available sealed on both sides with PTFE seals and can be fitted with a PEEK cage. PEEK offers excellent chemical resistance, 高温稳定性 (up to 300°C), and radiation resistance—complementing the ceramic material’s own extreme properties.
