Tech Products 51553-5 Vibration Isolator 1550 Lb

Product Description

The TECH PRODUCTS 51553-5 is a plate-to-plate vibration isolator rated for loads up to 1550 pounds. It uses a rubber-and-steel sandwich construction to absorb and dampen mechanical vibration between mounted equipment and its supporting structure. At 3-1/8 inches in diameter and 1-1/2 inches in height, this round isolator installs between flat mounting surfaces using a 1/2-13 threaded fastener. HVAC mechanics, millwrights, and mechanical contractors install this type of component under compressors, fan assemblies, pumps, and similar rotating equipment to reduce structure-borne noise and protect both the equipment and the mounting surface from vibration fatigue.

This isolator suits residential and light commercial mechanical installations where vibration control is required between two flat plate surfaces. Typical applications include rooftop units, air handlers, condensing units, hydronic pumps, and small compressors. The plate-to-plate mount style makes it well suited for equipment frames and equipment pads where both the top and bottom faces of the isolator bear against flat steel or concrete surfaces. No specific compatible model listings are provided by the manufacturer for this part number.

Key Features

• 1550 pound maximum load capacity for heavy mechanical equipment support
• Plate-to-plate mount type isolates vibration between two flat surfaces
• 1/2-13 thread size for standard fastener compatibility
• 3-1/8 inch overall diameter in a compact round profile
• 1-1/2 inch installed height keeps equipment mounting height low
• Round shape simplifies alignment during installation

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for plate-mount mechanical equipment installations requiring a 1/2-13 fastener and a load rating up to 1550 pounds.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical contractors. De-energize and isolate the equipment from all power and fluid sources before lifting or repositioning it to install or replace isolators. Ensure both mating plate surfaces are clean and flat before seating the isolator. Fastener torque should follow the equipment manufacturer's specifications and applicable mechanical codes.
