440C Stainless Steel Ball Bearings with ZZ Metal Shields – ABEC-9 Precision

•440C Stainless Steel, 58HRC Hardness

Rings and balls crafted from 440C stainless steel, hardened to 58HRC for excellent wear resistance;

weak magnetic with general corrosion resistance — stable and durable in humid

or hygiene-demanding conditions.

•ZZ Double Stainless Steel Shields

Non-contact metal shields on both sides seal out dust and retain grease with almost no added

friction or heat — lower starting torque and higher speeds than rubber-sealed bearings.

Precision-ground to ABEC-9 for high rotational accuracy, ultra-low noise, and minimal vibration

— smooth, stable running even at high RPM.

•Grease Lubrication & C0 Clearance

Pre-filled with quality grease and built to C0 standard clearance for smooth, quiet,

maintenance-free rotation right out of the box.

•Versatile Applications

Ideal for fishing reels, food equipment, kitchen appliances, medical instruments, and other

compact precision machinery.
