DHK.03.0258 599.7 mm 440 mm 545.5 mm 73.4 mm Frequently Asked Questions about DHK.03.0258 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of DHK.03.0258 Single Row Cylindrical Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
The Open Type engineered for DHK.03.0258 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies DHK.03.0258 with a precision bore diameter (d) of 440 mm, an outside diameter (D) of 599.7 mm, and a nominal ring width (B) of 73.4 mm. This configuration yields an effective cross-sectional wall thickness of 79.9 mm and an envelope ratio (D/d) of 1.36, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing DHK.03.0258 Single Row Cylindrical 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.
