Mars 74625 BX55 V-belt 5/8 X 58 Inch

Product Description

The MARS Motors Armatures 74625 is a BX55 cogged V-belt measuring 5/8 inch wide by 58 inches in outside circumference. Cogged V-belts are used to transfer rotational power from a motor sheave to a driven component such as a blower wheel, condenser fan, or pump. The BX designation indicates a notched or cogged profile, which reduces bending resistance, runs cooler, and increases efficiency compared to a standard wrapped belt of the same cross-section. This belt is commonly installed by HVAC technicians and mechanical service professionals during preventive maintenance or belt replacement service calls.

BX-series V-belts are standard in residential and light commercial HVAC equipment, including belt-drive air handlers, furnaces with blower assemblies, and package units. The 5/8 inch by 58 inch dimension suits a range of mid-size blower and fan drive applications. This belt is a direct replacement for worn or failed BX55 belts wherever that designation is called for on the equipment nameplate or belt drive specification.

Key Features

• BX55 cogged V-belt profile reduces flex resistance and heat buildup during operation
• 5/8 inch cross-section width matched to standard BX-class sheaves and pulleys
• 58 inch outside circumference for mid-range blower and fan drive applications
• Cogged design improves grip and power transmission efficiency over standard wrapped belts
• Direct OEM-style replacement for any application specifying a BX55 belt

Compatibility

Designed as a direct replacement for any belt-drive system specifying a BX55 V-belt with a 5/8 inch cross-section and 58 inch outside circumference, including residential and light commercial HVAC blower and fan drive assemblies.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service professionals. Always de-energize the unit and follow lockout/tagout procedures before removing belt guards or accessing the drive assembly. Do not pry the belt over sheave flanges using tools that could damage the sheave grooves; instead, relieve tension by adjusting motor position before seating the new belt. After installation, verify belt tension and alignment per the equipment manufacturer's specifications before returning the unit to service.
