Carrier KT63ZZ139 Bearing 1-15/16" Bore

The Carrier KT63ZZ139 is an Anti-Friction Ball Bearing, used in Carrier HVAC equipment to reduce friction. It has a cast/malleable iron housing and a 1-15/16” (1.9375”) bore diameter. The ball bearings are particularly for moderate loads and are better suited for high-speed operations with low friction. In HVAC systems, bearings help support rotatable shafts which control different elements of the systems for instance the blowers and the fan motors. This bearing reduces the contact surface area between the shaft and the bearing housing and reduces friction, energy consumption, and damage to these components.
