Description
The Nordyne 921457 is a standard duty ball bearing insert designed for dependable, long-service performance in HVAC blower and fan shaft applications. Featuring a 1-inch bore diameter, this insert mounts securely using a setscrew locking mechanism that holds the bearing firmly to the shaft, preventing unwanted movement under load and vibration.
Dual-Seal Protection
This bearing insert is equipped with both a contact seal and a flinger seal, providing a two-stage defense against contaminants. The contact seal creates a positive barrier against dust, dirt, and moisture ingress, while the flinger seal deflects debris before it can reach the sealing surface — extending bearing life in demanding HVAC environments.
