Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7000 CD/P4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 7000 CD/P4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7000 CD/P4A with a precision bore diameter (d) of 10 mm, an outside diameter (D) of 26 mm, and a nominal ring width (B) of 8 mm. This configuration yields an effective cross-sectional wall thickness of 8.0 mm and an envelope ratio (D/d) of 2.6, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7000 CD/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (10 mm x 26 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
