Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 71828 CDGB/P4 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (140 mm bore side) ensures perfect planar contact without edge binding.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 71828 CDGB/P4. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71828 CDGB/P4 with a precision bore diameter (d) of 140 mm, an outside diameter (D) of 175 mm, and a nominal ring width (B) of 18 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 71828 CDGB/P4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (140 mm x 175 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
