Description
The SA20722GKML (commonly designated as SA207-22G) is a KML brand 1-3/8 inch bore, standard-duty radial insert ball bearing. It features a spherical outer diameter and a narrow inner ring that locks securely onto a shaft using an eccentric locking collar. The "G" suffix indicates that it is a greasable profile featuring a built-in lubrication pathway.
Key Specifications
- Bore Diameter (Shaft Size): 1-3/8 in (1.375 in / 34.925 mm)
- Outer Diameter (OD): 2.835 in (72 mm)
- Outer Ring Width: 0.669 in (17 mm)

- Locking Device: Eccentric self-locking collar
- Lubrication Type: Greasable / Re-lubrication facility ("G" suffix)

Design & Performance
- Self-Alignment: Designed with a spherical outer ring profile that fits cleanly into matching mounted housings, allowing the assembly to swivel and automatically adjust for minor shaft misalignments.
- Mechanical Shaft Grip: The cam-action eccentric locking collar forms a tight mechanical connection directly with the shaft, preventing slipping on applications where rotation primarily moves in a single direction.
- Re-Greasable System: Outfitted with an external grease groove and a precisely machined lubrication hole, making it compatible with housings that feature grease zerks for scheduled re-greasing.
- Internal Sealing: Equipped with robust rubber contact lip seals to trap factory lubrication inside the raceways while continuously blocking fine dust, water splashes, and field debris.
Common Applications
- Stamped steel flangettes and mounted bearing units (such as the SAPFT or SAPF series)
- Agricultural machinery, grain handling augers, and harvesting equipment
- Industrial packaging machines, sorting tables, and material handling conveyor loops
- Commercial HVAC units, large exhaust blowers, and air handling equipment
