Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting N240R over a 200 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.
To ensure optimum performance of CHG Bearing N240R Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 200 mm bore. For the 360 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies N240R with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 58 mm. This configuration yields an effective cross-sectional wall thickness of 80.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
Each N240R 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 (200 mm bore side) ensures perfect planar contact without edge binding.
