Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 787/1184 with a precision bore diameter (d) of 1184 mm, an outside diameter (D) of 1524 mm, and a nominal ring width (B) of 125 mm. This configuration yields an effective cross-sectional wall thickness of 170.0 mm and an envelope ratio (D/d) of 1.29, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for 787/1184 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Standard batches of CHG Bearing 787/1184 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.
Model 787/1184 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 1184 mm) and steep thermal gradients between inner and outer rings.
