HJB045XP0-1 130.175 mm 114.3 mm 7.9375 mm Frequently Asked Questions about HJB045XP0-1 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Sealed engineered for HJB045XP0-1 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.
Model HJB045XP0-1 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 114.3 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HJB045XP0-1 with a precision bore diameter (d) of 114.3 mm, an outside diameter (D) of 130.175 mm, and a nominal ring width (B) of 7.9375 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.14, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies HJB045XP0-1 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
