71814 ACD/P4 90 mm 70 mm 10 mm Frequently Asked Questions about 71814 ACD/P4 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 71814 ACD/P4 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 (70 mm bore side) ensures perfect planar contact without edge binding.
Model 71814 ACD/P4 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 70 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 71814 ACD/P4 Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71814 ACD/P4, FAG 71814 ACD/P4, NSK 71814 ACD/P4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Built for demanding industrial environments, the 71814 ACD/P4 Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
