The FZ Shielded HC is constructed of Stainless Steel and has 10 Si3n4 balls. The shields help to keep dust and lint from entering the grooves, keeping you spinning at top performance for longer times. Low noise, fast spins and tight tolerance. This bearing is also much more durable than other shielded spinner bearings. Sold in packs of two.
Cleaning: This bearing can be cleaned in high ISO. An immediate and thorough drying with a hair dryer on cool is highly recommended.
