    AI Overview
    High-precision, heavy-duty (HD) FR8ZZ hex bearings are specifically designed to prevent cracking, a common failure in high-load applications like FRC robot drives. These bearings feature reinforced, thicker inner races designed to handle high radial loads, preventing the inner race from cracking at the corners of the hexagon. 
    Key Features for Preventing Cracking: 
    • Heavy Duty Inner Race: Thicker, stronger inner race material provides enhanced strength.
    • Precision-Ground Hex Fit: Ensures a perfect 1/2" fit to reduce stress concentrations.
    • High-Quality Steel: Constructed with durable bearing steel (such as 52100) to resist fracturing under shock loads.
    • Shielded Design: Metal shields (ZZ) provide protection while maintaining high performance, up to 32,000 RPM. 
    Installation and Maintenance Tips: 
    • Use Proper Tools: Avoid hammering the bearing directly. Use a press or proper installation tool to avoid internal damage and misalignment.
    • Inspect Shafts: Ensure the 1/2" hex shaft is clean and free of burrs to prevent uneven stress on the inner race.
    • Proper Loading: While designed for high loads, ensure the bearing does not exceed its maximum load rating (approx. 700 lbf dynamic, 500 lbf static for heavy-duty models). 
    Common, high-quality, heavy-duty options include the AndyMark FR8ZZ-HexHD.
