N 1013 KTNHA/SP 100 mm 65 mm 18 mm Frequently Asked Questions about N 1013 KTNHA/SP Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects N 1013 KTNHA/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.
To extend the trouble-free lifespan of CHG Bearing N 1013 KTNHA/SP, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Absolutely. The CHG Bearing N 1013 KTNHA/SP Super-Precision Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF N 1013 KTNHA/SP, FAG N 1013 KTNHA/SP, NSK N 1013 KTNHA/SP. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The Open Type engineered for N 1013 KTNHA/SP 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.
