Description
The SAF20620GKML (commonly designated as SAF206-20G) is a KML brand 1-1/4 inch bore, light-to-normal duty cast iron 4-bolt square flange mounted bearing unit. It pairs a heavy-duty four-bolt square housing with a narrow inner ring insert bearing that secures to the shaft via an eccentric locking collar. The "G" suffix indicates it features a greasable housing profile with an integrated path for re-lubrication.

Design & Performance
- Four-Bolt Structural Stability: The square flange housing layout distributes heavy structural loads symmetrically across four mounting points, keeping shafts rigid in high-vibration applications.
- Self-Aligning Insert: Features a precision-ground bearing insert with a spherical outer diameter, allowing the unit to swivel internally to automatically compensate for minor shaft deflections or structural mounting errors.
- Single-Direction Locking: The cam-action eccentric locking collar forms a mechanically bound, reliable hold directly on the shaft, making it ideal for machinery operating in a uniform rotational direction.
- Grease Pathway System: Outfitted with an external grease groove and a machined lubrication hole on the outer ring, letting you purge old grease and replenish the system under a standard industrial maintenance schedule.
Common Applications
- Farm machinery, harvesting equipment, and grain handling augers
