N 1014 KTNHA/SP 110 mm 70 mm 20 mm Frequently Asked Questions about N 1014 KTNHA/SP Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies N 1014 KTNHA/SP with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 110 mm, and a nominal ring width (B) of 20 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing N 1014 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.
When fitting N 1014 KTNHA/SP over a 70 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.
Each N 1014 KTNHA/SP 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.
