It features a 1 inch finished bore diameter and a 2.7 inch outer diameter, with a belt pitch diameter of 2.1 inches for Type 4L or A belts. The overall length through the bore measures 1-31\/32 inches. At 1.45 pounds, this sheave is a compact, durable component suited for belt-drive configurations where reliable torque transfer is required.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly installed in light- to medium-duty belt drive systems, including blower assemblies, fan drives, and auxiliary equipment found in commercial and residential HVAC units. The two-groove configuration allows dual-belt setups, increasing load capacity and redundancy in drive systems. Licensed HVAC technicians and mechanical contractors typically handle installations involving sheave replacement or drive system reconfigurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 1 inch — ready to install without additional machining\u003c\/li\u003e\n  \u003cli\u003eTwo groove design supports dual V-belt configurations for increased drive capacity\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides strength and wear resistance in belt drive applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with Type 4L or A belts with a 2.1 inch pitch diameter\u003c\/li\u003e\n  \u003cli\u003eCompact profile with 2.7 inch OD and 1-31\/32 inch bore length suits tight drive spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for two-groove V-belt drive systems using Type 4L or A belts with a matching 1 inch bore shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified mechanic.
