6338EA 400 mm 190 mm 78 mm Frequently Asked Questions about 6338EA Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 6338EA with a precision bore diameter (d) of 190 mm, an outside diameter (D) of 400 mm, and a nominal ring width (B) of 78 mm. This configuration yields an effective cross-sectional wall thickness of 105.0 mm and an envelope ratio (D/d) of 2.11, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 6338EA Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 190 mm bore. For the 400 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 6338EA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (190 mm x 400 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Sourcing 6338EA directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Deep Groove Ball Bearings.
