626 19 mm 6 mm 6 mm Frequently Asked Questions about 626 Metric Miniature Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 626 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
When fitting 626 over a 6 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Beyond standard alloy steel, CHG Bearing can customize the 626 Metric Miniature Deep Groove Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
