63804 32 mm 20 mm 10 mm Frequently Asked Questions about 63804 Metric Super-Thin Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 63804 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.
Every production batch of CHG Bearing 63804 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 63804 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 20 mm bore. For the 32 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 63804 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (20 mm x 32 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
