NN 3017 KTN9/VQ554 130 mm 85 mm 34 mm Frequently Asked Questions about NN 3017 KTN9/VQ554 Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each NN 3017 KTN9/VQ554 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 (85 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the NN 3017 KTN9/VQ554 Super-Precision Cylindrical Roller 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.
The Open Type engineered for NN 3017 KTN9/VQ554 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.
Absolutely. The CHG Bearing NN 3017 KTN9/VQ554 Super-Precision Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NN 3017 KTN9/VQ554, FAG NN 3017 KTN9/VQ554, NSK NN 3017 KTN9/VQ554. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
