NN 3013 KTN/SP 100 mm 65 mm 26 mm Frequently Asked Questions about NN 3013 KTN/SP Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting NN 3013 KTN/SP over a 65 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Absolutely. The CHG Bearing NN 3013 KTN/SP Super-Precision Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NN 3013 KTN/SP, FAG NN 3013 KTN/SP, NSK NN 3013 KTN/SP. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As standard production, CHG Bearing subjects NN 3013 KTN/SP to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Beyond standard alloy steel, CHG Bearing can customize the NN 3013 KTN/SP Super-Precision Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
