Carrier KA56TR056 Grommet

The Carrier KA56TR056 Motor Grommet is a critical isolation component designed specifically for HVAC blower motor mounting applications in Carrier, Bryant, and Payne air handlers and furnaces. Engineering precision in the vibration isolation layout ensures that harmonic transfer from the 5.6-inch diameter motor to the blower housing is minimized, preventing structural fatigue and reducing decibel output during high-static operation. This OEM replacement grommet is molded from high-density synthetic elastomer, providing superior resistance to the thermal cycling and petroleum-based lubricants commonly encountered in residential and light commercial air moving assemblies.

For contractors performing HVAC blower motor repair, utilizing genuine Carrier furnace parts like the KA56TR056 ensures strict adherence to the original equipment manufacturer's specifications for clearance and torque. These grommets are essential for maintaining proper blower wheel alignment and protecting the motor bearings from premature wear caused by excessive oscillation. When replacing a failed motor, installing new vibration dampening grommets is a standard industry best practice to ensure peak system longevity and efficient airflow performance across the heat exchanger.

• Ensures precise vibration isolation to eliminate cabinet rattle and mechanical resonance.
• Compatible with standard 5.6-inch motor mounts used in various Carrier family brands.
• High-durometer elastomer construction resists hardening and cracking from constant heat exposure.
• Provides the necessary cushioning to maintain HVAC motor alignment within the blower housing.

Is this grommet compatible with non-OEM universal motors?
Yes, provided the motor frame size is standard and the mounting bracket accepts Carrier KA56TR056 specifications for hole diameter and thickness.

Why is replacing grommets necessary when installing a new motor?
Old grommets lose their elasticity over time; new blower motor grommets are required to restore the dampening properties necessary to prevent noise complaints and bearing failure.

How many grommets are required for a standard motor mount?
Most mounting brackets utilize a set of three or four, though this varies by the specific furnace blower assembly configuration.
