Source1 2814709000 Belt Drive Bx56 Pitch 57.8

Product Description

The Source1 2814709000 is a BX56 cogged V-belt designed for use in belt-drive HVAC systems. It features a pitch length of 57.8 inches, making it a precise replacement for systems that require this specific belt sizing. BX-series belts are a staple in heating, ventilation, and air conditioning equipment, commonly used to transfer power from motors to blower wheels and fan assemblies. HVAC technicians rely on this type of belt for reliable, efficient operation in air handlers, rooftop units, and furnace blower assemblies. The BX designation means this belt has a cogged, or notched, underside. Those cogs allow the belt to flex more easily around smaller sheaves and pulleys, reducing heat buildup and slipping. This design improves energy efficiency compared to standard wrapped V-belts. The cogged construction also extends service life by reducing internal stress during operation. The 57.8 inch pitch length is a key specification when matching a replacement belt to existing pulleys and drives. Using the correct pitch length ensures proper belt tension, prevents premature wear, and avoids slippage that can reduce blower performance. Installers should always verify the pitch length and belt cross-section before installation. The BX56 fits a standard BX cross-section profile, which measures approximately 21 thirty-seconds of an inch deep and 21 thirty-seconds wide at the top. This profile is compatible with BX-rated sheaves commonly found in commercial and residential HVAC equipment. Source1 is a trusted brand in the HVAC parts and supply industry, offering OEM-quality components for service contractors and equipment technicians. This belt is a direct replacement for worn or broken drive belts in blower and fan drive assemblies, helping restore full airflow and system efficiency quickly.
