💡 What does C3 clearance mean in sealed ball bearings?

C3 clearance allows a little extra space between the balls and raceways for higher speed and thermal expansion.

• Supports higher RPMs without overheating

• Reduces internal friction during fast rotation

• Ideal for motors, gearboxes, and power tools

• Sealed design improves grease retention and longevity
