Should you spray WD-40 on bearings?

No, you should not use standard WD-40 as a lubricant for bearings because it's primarily a solvent and water displacer, not a long-lasting lubricant; it strips existing grease, attracts dirt, and leaves behind a gummy residue, leading to premature wear and failure, though specific WD-40 Specialist products (like White Lithium Grease or PTFE Lubricant) are designed for lubrication. For proper lubrication, use dedicated bearing grease or specialty oils after cleaning bearings thoroughly with a proper solvent or degreaser.
