S-94610A306 0.531" ID x 1.25" OD Ultra-High-Temperature Ceramic Washers

Key Features & Benefits at a Glance

• Extreme heat resistance – withstands continuous temperatures up to 3000°F, preventing deformation and maintaining performance in high-temperature industrial processes.
• Excellent electrical insulation – ceramic material provides reliable non-conductive properties, reducing risks of electrical shorts in sensitive equipment.
• Precise dimensional fit – 0.531" ID ensures secure seating on 1/2" screws, while 1.25" OD distributes load evenly to prevent surface damage.
• Consistent thickness control – 0.090-0.112" thickness range offers uniform pressure distribution and vibration resistance in assembled components.
• Chemical and corrosion inertness – off-white ceramic composition resists oxidation, acids, and harsh chemicals for long-term reliability.
• Regulatory compliance assurance – meets RoHS 3 and REACH standards, supporting safe use in regulated industries and global supply chains.
• Lightweight and durable – ceramic construction reduces component weight without sacrificing mechanical strength or thermal stability.

Professional Applications & Engineering Value

This ceramic flat washer is engineered for extreme environments where metal washers fail, such as furnace linings, power generation systems, and aerospace components. Its high-temperature stability up to 3000°F ensures structural integrity under thermal cycling, while the off-white ceramic material offers superior thermal and electrical insulation. The precise inch system dimensions (0.531" ID, 1.25" OD) provide reliable seating for 1/2" screw applications, distributing clamp load effectively to prevent joint loosening in vibrating machinery. Ideal for industrial washers used in heat treatment equipment, kilns, and semiconductor manufacturing, where high heat resistance and compliance with safety standards are critical.
