Built with a \u003cstrong\u003e7\/8\" finished bore\u003c\/strong\u003e and a \u003cstrong\u003e4.75\" outside diameter\u003c\/strong\u003e, this component is designed to maintain exact blower speeds in Liebert precision cooling units. As an \u003cstrong\u003eOEM replacement part\u003c\/strong\u003e, it ensures proper belt alignment and consistent torque transmission, which are vital for preventing premature bearing failure and maintaining airflow in data centers or medical facilities. This \u003cstrong\u003eCI sheave\u003c\/strong\u003e is balanced to meet rigid industrial standards, minimizing vibration and extending the service life of the drive package. When performing routine PMs, technicians should verify the \u003cstrong\u003e4.75-inch diameter\u003c\/strong\u003e and \u003cstrong\u003e7\/8-inch shaft\u003c\/strong\u003e compatibility to ensure the blower assembly operates within its designed CFM parameters. Its heavy-duty cast iron construction provides the thermal stability and wear resistance required for 24\/7 continuous duty cycles.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for Technicians:\u003c\/strong\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Dimensional Accuracy:\u003c\/strong\u003e Guarantees a precise fit on \u003cstrong\u003e7\/8\" blower shafts\u003c\/strong\u003e without the need for additional bushings or machining.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVibration Dampening:\u003c\/strong\u003e The high-density \u003cstrong\u003ecast iron material\u003c\/strong\u003e absorbs harmonic resonance, protecting the motor and fan assembly from stress.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Airflow:\u003c\/strong\u003e Maintains the exact \u003cstrong\u003e4.75\" pitch diameter\u003c\/strong\u003e required to sustain designed static pressure in Liebert environmental systems.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e Resistant to the grooving and surface wear common in high-static applications using standard V-belts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat belt section is compatible with the B-005AS?\u003c\/strong\u003e\u003cbr\u003e\nThis \u003cstrong\u003e1-groove sheave\u003c\/strong\u003e is typically designed for use with standard A-section (4L) or B-section (5L) V-belts, though technicians should always match the belt profile to the existing drive configuration for optimal grip.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this sheave include a keyway and set screw?\u003c\/strong\u003e\u003cbr\u003e\nYes, this is a finished-bore sheave that comes standard with a machined keyway and a hardened set screw for secure mounting on the motor or blower shaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this part suitable for variable frequency drive (VFD) applications?\u003c\/strong\u003e\u003cbr\u003e\nYes, the \u003cstrong\u003eLiebert B-005AS\u003c\/strong\u003e is balanced for use in both constant-volume and VFD-controlled blower systems common in precision cooling equipment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
