DHK.03.0018 830 mm 600 mm 655 mm 150 mm Frequently Asked Questions about DHK.03.0018 Single Row 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 DHK.03.0018 with a precision bore diameter (d) of 600 mm, an outside diameter (D) of 830 mm, and a nominal ring width (B) of 150 mm. This configuration yields an effective cross-sectional wall thickness of 115.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing DHK.03.0018 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 600 mm bore. For the 830 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing DHK.03.0018 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (600 mm x 830 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
In its sealed configuration (Open Type), CHG Bearing pre-charges DHK.03.0018 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
