Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71802 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.
In its sealed configuration (Open / Contact Seal Options), CHG Bearing pre-charges 71802 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
The CHG Bearing 71802 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Model 71802 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.
