NA127096/127136D 349.148 mm 244.475 mm Frequently Asked Questions about NA127096/127136D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for NA127096/127136D 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.
To ensure optimum performance of CHG Bearing NA127096/127136D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 244.475 mm bore. For the 349.148 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 NA127096/127136D with a precision bore diameter (d) of 244.475 mm, an outside diameter (D) of 349.148 mm, and a nominal ring width (B) of 133.35 mm. This configuration yields an effective cross-sectional wall thickness of 52.3 mm and an envelope ratio (D/d) of 1.43, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for NA127096/127136D, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
