Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HSX011840 HSX Series Crossed Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 200 mm bore. For the 250 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 HSX011840 with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 250 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
The CHG Bearing HSX011840 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.
Standard batches of CHG Bearing HSX011840 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
