Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 234964 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Model 234964 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 320 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 234964 Tapered Roller Thrust Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 234964, FAG 234964, NSK 234964. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 234964 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 (320 mm bore side) ensures perfect planar contact without edge binding.
