The S686 bearing boasts excellent corrosion resistance, non-magnetic properties and high-temperature stability, and is suitable for applications in demanding fields such as medical equipment, food processing, precision instruments and aerospace. Key Specifications: Bore Diameter (d): 6 mm Outer Diameter (D): 13 mm Width (B): 3.5 mm Dynamic Load Rating (Cr): Approximately 2.2 kN Static Load Rating (Cor): Approximately 0.98 kN Material: Stainless steel rings and ceramic balls. 440C is a martensitic, high-carbon stainless steel that can be hardened to 58-60 HRC, offering a superb combination of corrosion resistance, wear resistance, and durability. Shields/Seals: Commonly supplied with non-contact stainless steel shields (ZZ) to retain lubrication while minimizing friction. Rubber seals are available for enhanced protection against fine contaminants. Precision: Manufactured to ABEC 1 (RBEC 1) or higher precision grades, ensuring smooth, low-noise, and low-vibration operation critical in sensitive equipment. Lubrication: Pre-lubricated with a minimal quantity of high-performance, corrosion-inhibiting grease suitable for the bearing's intended application range (e.g., food-safe or high-temperature grease options available).
