Support bearing/bushing for agitator head assembly providing radial support and reducing friction between rotating shaft and stationary housing.
A precision mechanical component designed to support the rotating shaft within an agitator head assembly, maintaining proper alignment while minimizing friction and wear. It consists of either rolling-element bearings (ball or roller) or plain bushings (sleeve bearings) that interface between the shaft and housing, handling radial loads and ensuring smooth rotational motion in mixing applications.

Bearings use rolling elements (balls/rollers) for lower friction at higher speeds, while bushings provide larger contact areas for better shock absorption and are often self-lubricating. Bearings offer higher precision, bushings handle more contamination.
Typical service life is 10,000-20,000 operating hours depending on load, speed, and environment. Regular vibration analysis and temperature monitoring can predict failure before catastrophic breakdown occurs.
Standard support bearings primarily handle radial loads. For combined loads, angular contact bearings or tapered roller bearings are recommended. Most agitator designs separate radial and axial load handling.
