Lau g078104818 Two-groove V-belt Pulley 5.95 in Od

Product Description

The LAU g078104818 is a two-groove V-belt pulley designed for use in HVAC blower and fan drive assemblies. With an outer diameter of 5.95 inches and a bore size of 1.125 inches, this pulley is built to transfer rotational power between the motor shaft and blower wheel via matched V-belts. Two-groove pulleys allow for dual-belt drive configurations, which distribute load more evenly and reduce slip under higher torque conditions. This component is typically installed by HVAC technicians during system commissioning or when replacing worn or damaged drive components in air handling units and belt-drive blower assemblies.

This pulley is suited for belt-drive blower systems found in residential and light commercial HVAC applications. It fits shaft configurations requiring a 1.125-inch bore and pairs with standard V-belts in two-belt drive setups. Common install scenarios include replacement of original equipment pulleys on belt-drive air handlers, furnace blowers, and ventilation fan assemblies where maintaining correct sheave ratio and belt alignment is critical to system performance and efficiency.

Key Features

• Two-groove design supports dual V-belt drive configurations for improved load distribution
• 5.95-inch outer diameter allows for precise blower speed and airflow tuning via sheave ratio selection
• 1.125-inch bore size fits standard motor and blower shaft diameters common in HVAC equipment
• OEM-style replacement pulley for belt-drive blower and fan assemblies
• Single-unit packaging suitable for one-for-one field replacement

Compatibility

Designed as an OEM-style replacement pulley for belt-drive blower and fan assemblies requiring a two-groove sheave with a 5.95-inch outer diameter and a 1.125-inch bore.

Installation Notes

Installation should be performed by a qualified HVAC technician. Always disconnect and lock out power to the air handler or blower unit before removing the belt or accessing drive components. Ensure the new pulley is properly aligned with the mating sheave using a straightedge or laser alignment tool before tensioning the belts to manufacturer specifications. Inspect belts for wear and replace as needed when servicing the pulley.
