61802 24 mm 15 mm 5 mm Frequently Asked Questions about 61802 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 61802 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 15 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 61802 with a precision bore diameter (d) of 15 mm, an outside diameter (D) of 24 mm, and a nominal ring width (B) of 5 mm. This configuration yields an effective cross-sectional wall thickness of 4.5 mm and an envelope ratio (D/d) of 1.6, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing 61802, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Yes, 100% of 61802 Deep Groove Ball Bearings（618 / 619 SERIES） leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
