Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing HSX011820 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies HSX011820 with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 125 mm, and a nominal ring width (B) of 13 mm. This configuration yields an effective cross-sectional wall thickness of 12.5 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the HSX011820 HSX Series Crossed Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Model HSX011820 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 100 mm) and steep thermal gradients between inner and outer rings.
