Carrier KT63ZZ098 Bearing

As a field tech, you know that keeping a blower shaft or fan assembly stable depends entirely on the integrity of your pillow block bearing. The Carrier KT63ZZ098 is a high-performance, 1-3/16 inch bore diameter ball bearing designed for standard-duty 200 series applications. Built with a rugged cast or malleable iron housing, this factory authorized part ensures precise alignment and minimizes vibrational friction in critical HVAC replacement parts setups. It features a pre-lubricated design for immediate out-of-the-box installation and includes a reliable locking device to secure the shaft directly to the inner race. Whether you are performing an HVAC system diagnostic or a complete air handler repair, this OEM bearing replaces legacy part numbers including KT63BE091, 48MA400453, and KT63CZ088. With a mounting center distance of 4-5/8 inches and a base-to-shaft center height of 1-11/16 inches, it meets the exact specifications required for high-volume Carrier, Bryant, and Payne air handling units.
