Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 44.5*73.62 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit ( mm bore side) ensures perfect planar contact without edge binding.
Absolutely. The CHG Bearing 44.5*73.62 Tapered Rollers is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 44.5*73.62, FAG 44.5*73.62, NSK 44.5*73.62. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Engineered according to international ISO boundary plans, CHG Bearing supplies 44.5*73.62 with a precision bore diameter (d) of mm, an outside diameter (D) of mm, and a nominal ring width (B) of mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
Model 44.5*73.62 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 mm) and steep thermal gradients between inner and outer rings.
