Lovejoy 68514417452 Elastomeric Drive Tensioner V-belt

Product Description

The LOVEJOY 68514417452 is an elastomeric drive tensioner designed to maintain consistent belt tension in A, B, and 3L V-belt drive systems. Constructed from natural rubber, this tensioner absorbs vibration and accommodates minor misalignment, reducing wear on belts and sheaves. With an overall length of 2.52 inches and an overall width of 1.77 inches, it fits into compact drive assemblies without requiring significant modification to existing hardware. HVAC technicians, mechanical contractors, and equipment service pros install this type of tensioner on belt-driven blowers, fans, and light-duty power transmission systems.

This tensioner is suited for residential and light commercial applications where A, B, or 3L cross-section V-belts are used. Typical installations include belt-driven air handlers, fan units, and auxiliary drive systems that require a low-profile, maintenance-friendly tensioning solution. Its elastomeric construction makes it a practical choice for environments where vibration dampening is a priority alongside consistent drive performance.
