• Corrosion Resistance: Ideal for wet, chemical, or outdoor environments; prevents rust unlike carbon steel.
• Durability: High hardness reduces wear; low torque for smooth operation and vibration neutralization.
• Hygiene and Cleanliness: Non-magnetic, easy to clean; recommended for food-grade or medical applications.
• Versatility: Omnidirectional movement with a low profile; available in dishwasher-safe variants for pet bowls (a niche use).

Common grades include:

• Main Ball: 420 stainless steel for durability and hardness.
• Cover/Retainer: 304 stainless steel for corrosion resistance.
• Cup/Housing: 410 stainless steel for strength; carbon steel housings are available for non-corrosive needs. Alternatives like 201 or 301 stainless steel are used for cost-sensitive applications, while nylon or carbon steel options exist for lighter loads.

• Material Handling: Used in ball transfer tables, turntables, cargo rolling decks, and air cargo systems for omnidirectional load movement (e.g., European air cargo containers).
• Polishing and Grinding: Ideal for milling media in hardware polishing, especially for irregular or anomalous workpieces; removes burrs and achieves smooth finishes in metal processing.
• Other Uses: Conveyor systems, sorting platforms, and lifting equipment; stainless steel variants excel in corrosive environments like food processing or outdoor settings.

A stainless steel flying saucer ball is a compact, disc-shaped bearing or grinding media made primarily from corrosion-resistant stainless steel (e.g., grades 304, 410, or 420). It functions as a ball transfer unit for smooth, multi-directional movement in conveyors or as polishing media for hardware surfaces. The "flying saucer" name comes from its UFO-like profile, allowing it to recess into surfaces for flush installation.
