352144 370 mm 220 mm Frequently Asked Questions about 352144 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 352144 Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Beyond standard alloy steel, CHG Bearing can customize the 352144 Double Row Tapered 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.
To ensure optimum performance of CHG Bearing 352144 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 220 mm bore. For the 370 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 352144 with a precision bore diameter (d) of 220 mm, an outside diameter (D) of 370 mm, and a nominal ring width (B) of 195 mm. This configuration yields an effective cross-sectional wall thickness of 75.0 mm and an envelope ratio (D/d) of 1.68, delivering compact rigidity for OEM machinery housings.
