Tech Products 51552-4 Vibration Isolator 980 Lb Stud/stud

Product Description

The TECH PRODUCTS 51552-4 is a stud/stud vibration isolator rated for loads up to 980 pounds. It is designed to absorb and dampen mechanical vibration between equipment and supporting structures, reducing noise transmission and protecting connected components from fatigue. The isolator measures 3.125 inches in diameter and 1.5 inches in height, with a 1/2-13 threaded stud configuration on both ends and a thread length of 1.625 inches. HVAC technicians, mechanical contractors, and industrial equipment installers use this type of isolator as a mounting point between vibrating machinery and frames, pads, or structural supports.

This isolator is suited for commercial and industrial HVAC applications as well as general mechanical equipment mounting where vibration control is required. Typical installations include air handlers, compressors, pumps, fans, and other rotating equipment that transmit vibration to building structures or equipment frames. Its round profile and stud/stud mount configuration make it straightforward to integrate into both new installations and retrofits where vibration isolation is a service or code requirement.

Key Features

• 980-pound maximum load capacity for heavy-duty equipment mounting
• Stud/stud mount type with 1/2-13 thread on both ends
• 1.625-inch thread length provides secure engagement depth
• 3.125-inch overall diameter in a compact round profile
• 1.5-inch overall height fits tight mechanical clearances
• Round shape allows consistent load distribution across the mount

Compatibility

Designed as a stud/stud vibration isolator for commercial and industrial mechanical equipment installations requiring 1/2-13 threaded mounts and load capacities up to 980 pounds.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. De-energize and lock out all equipment before servicing or replacing vibration isolators. Use appropriately sized wrenches on both studs to avoid over-torquing, which can damage the isolator body or bonded elastomer. Verify that the isolator load rating meets or exceeds the actual equipment weight per mounting point before installation.
