Aqua Max Bearing 6303 — Pool Pump Replacement

Replacement 6303 bearing for pool pump motors. The bearings support the motor shaft and allow it to spin freely. When bearings wear out, the pump becomes noisy — a grinding or screeching sound that gets worse over time. Replacing worn bearings restores quiet operation and prevents further damage to the motor shaft and windings. The 6303 is a heavier-duty bearing than the 6203, typically used on larger pump motors.

Specifications

Bearing number: 6303. This is a standard metric bearing size (wider than the 6203 series). Check your pump’s motor plate or service manual to confirm the correct bearing number before ordering — using the wrong size will not fit.
