Mars 94353 A-49 Multiple V-belt

Product Description

The MARS 94353 is an A-49 multiple V-belt designed for use in belt-driven HVAC and mechanical equipment. V-belts in the A-series profile transmit rotational power between a motor sheave and a driven component such as a blower wheel or fan. The A-49 designation identifies both the cross-section profile and the outside circumference length, making correct sizing straightforward when replacing a worn or broken belt. This belt is suited for installation by HVAC technicians and mechanical service professionals working on air handling and ventilation equipment.

A-49 multiple V-belts are commonly found in commercial and residential air handlers, rooftop units, and belt-drive blower assemblies where a matched belt set is required to distribute load evenly across multiple grooves. Using a matched set maintains consistent tension and reduces sheave wear. This part is appropriate for service work on belt-drive blower sections in packaged and split HVAC systems.

Key Features

• A-series cross-section profile for compatibility with standard A-groove sheaves
• A-49 designation indicates standardized outside circumference length for accurate replacement sizing
• Multiple V-belt configuration supports matched-set installations for even load distribution
• Suitable for belt-drive blower and fan applications in HVAC equipment

Compatibility

Designed as an OEM-style replacement A-49 multiple V-belt for belt-drive blower and fan assemblies using standard A-groove sheaves in commercial and residential HVAC equipment.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out electrical power to the unit before removing any belt guards or accessing the drive assembly. Never pry or force a belt over sheave flanges; always relieve tension via the motor adjustment rail before removing or installing the belt. When installing a matched multiple V-belt set, replace all belts in the set simultaneously to ensure even tension and load distribution.
