Description
SQ207-1 Square Bore Agricultural Bearing - 1" Square for Zero-Slippage Performance
Professional-grade SQ207-1 agricultural bearing featuring a precision 1-inch square bore for positive shaft engagement. The square bore design provides four-point contact that completely eliminates shaft rotation and slippage, making it ideal for high-torque agricultural applications.

Square Bore Advantage - Ultimate Positive Drive
Four-Point Contact System: The square bore creates four flat contact surfaces at 90-degree angles, providing superior torque transmission compared to hex or round bore designs. This geometry ensures absolute zero slippage even under extreme loads.
Why Square Bore Excels:
- Maximum Torque Transfer: Four flat sides provide optimal surface area for power transmission
- Zero Slippage Guarantee: Square geometry locks bearing to shaft with no possibility of rotation
- No Set Screws Required: Eliminates set screw loosening, shaft damage, and maintenance issues
- Perfect Alignment: 90-degree corners ensure precise bearing positioning
- Even Load Distribution: Four contact points prevent shaft wear and deformation
- Vibration Resistant: Square engagement stays secure in high-vibration environments
- Tool-Free Installation: Simply slide onto square shaft - no alignment or tightening needed
Double Rubber Seal Protection
Features double rubber seals (2RS) on both sides for comprehensive protection against agricultural contamination. The seals keep lubricating grease inside while blocking dirt, dust, moisture, and crop debris from entering the bearing.

Installation Benefits
Foolproof Installation:
- Verify shaft is clean 1" square
- Slide bearing onto square shaft
- Position bearing at desired location
- Bearing automatically locks in place - installation complete!
No Special Tools Required: The square bore design eliminates the need for set screws, alignment tools, or torque wrenches. Installation is fast and error-proof - perfect for field repairs.
Self-Indexing Design: The 90-degree corners of the square bore automatically align the bearing correctly on the shaft. No guesswork, no misalignment issues.
Maintenance-Free: Factory-sealed and pre-lubricated for the life of the bearing. No regreasing required under normal agricultural use.
