Carrier KT63CZ086 Bearing

As a technician, you know that keeping high-tonnage rooftop units and commercial chillers operational requires OEM-grade components that handle constant radial loads. The Carrier KT63CZ086 Bearing is a genuine Pillow Block Bearing replacement engineered for high-performance HVAC lubrication and shaft support. This 1 3/16 inch bore bearing features a robust cast iron housing with a gray finish, designed specifically to maintain axial alignment and reduce friction in demanding blower assemblies and motor applications.

This HVAC motor bearing includes a specialized locking device that secures the shaft to the inner race, preventing slippage during high-torque startups. With a total weight of 3.12 lbs and a compact footprint (approximately 9.29" depth x 3.78" width), this OEM Carrier replacement part integrates seamlessly into 48HCD and 50TC series RTUs. By minimizing vibration and supporting rotating shafts under industrial loads, it helps prevent premature mechanical failure and ensures the longevity of the entire drive train.
