63800 19 mm 10 mm 7 mm Frequently Asked Questions about 63800 Metric Super-Thin Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 63800 Metric Super-Thin Deep Groove Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To ensure optimum performance of CHG Bearing 63800 Metric Super-Thin Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 10 mm bore. For the 19 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 63800 with a precision bore diameter (d) of 10 mm, an outside diameter (D) of 19 mm, and a nominal ring width (B) of 7 mm. This configuration yields an effective cross-sectional wall thickness of 4.5 mm and an envelope ratio (D/d) of 1.9, delivering compact rigidity for OEM machinery housings.
Model 63800 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 10 mm) and steep thermal gradients between inner and outer rings.
