181-024801 327.025 mm 234.95 mm 196.85 mm Frequently Asked Questions about 181-024801 Four-Row Tapered 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 181-024801 with a precision bore diameter (d) of 234.95 mm, an outside diameter (D) of 327.025 mm, and a nominal ring width (B) of 196.85 mm. This configuration yields an effective cross-sectional wall thickness of 46.0 mm and an envelope ratio (D/d) of 1.39, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 181-024801 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Yes, 100% of 181-024801 Four-Row Tapered 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 181-024801 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.
