Manufactured from cast iron, this sheave features a 5\/8 inch bore diameter and a 4.95 inch outer diameter with a 3\/4 inch face width. The single groove profile is compatible with standard A-section and 4L-section V-belts, as well as 3L-section belts. Licensed HVAC technicians and millwrights typically install this component on blower assemblies, fan drives, and belt-driven mechanical equipment where a fixed-bore sheave is required.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC blower sections, exhaust fans, and general-purpose belt drive systems. The finished bore comes ready for installation on a 5\/8 inch shaft without additional machining. With a belt pitch diameter of 5.1 inches for B-section belts and 4.7 inches for A-section and 4L-section belts, it provides accurate belt engagement and consistent drive ratios. A pitch diameter of 4.36 inches applies when used with 3L-section belts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore design — 5\/8 inch bore diameter, ready for direct shaft installation\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in belt-drive service environments\u003c\/li\u003e\n  \u003cli\u003eSingle groove profile accepts standard A, 4L, and 3L V-belt sections\u003c\/li\u003e\n  \u003cli\u003e4.95 inch outer diameter with 3\/4 inch face width\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter of 4.7 inches for A-section and 4L-section belts\u003c\/li\u003e\n  \u003cli\u003eOverall bore length of 1-5\/32 inches through the hub\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement single groove sheave for V-belt drive systems using A-section, 4L-section, or 3L-section belts on 5\/8 inch shafts in residential and commercial mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or millwright. Always disconnect and lock out electrical power to the motor before removing or installing a sheave.
