HKB045XP0 130.175 mm 114.3 mm 7.9375 mm Frequently Asked Questions about HKB045XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies HKB045XP0 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.
Absolutely. The CHG Bearing HKB045XP0 Thin Section Four-Point Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HKB045XP0, FAG HKB045XP0, NSK HKB045XP0. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model HKB045XP0 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.
For international ocean and air freight, CHG Bearing packs HKB045XP0 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
