6204H 47 mm 20 mm 14 mm Frequently Asked Questions about 6204H Metric Stainless Steel Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 6204H Metric Stainless Steel Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 20 mm bore. For the 47 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Model 6204H is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 20 mm) and steep thermal gradients between inner and outer rings.
Quality starts with raw material selection: CHG Bearing crafts 6204H inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies 6204H with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 47 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 13.5 mm and an envelope ratio (D/d) of 2.35, delivering compact rigidity for OEM machinery housings.
