The bearing set to suit the Onga Pantera PPP1500 is a matched pair of sealed ball bearings for the pump motor: one for the drive end next to the wet end, and one for the fan end. Changing both together is the standard fix when the PPP1500 motor starts to rumble, whine or feel gritty, which often follows a shaft seal leak.
Signs the Onga Pantera PPP1500 bearings are worn
Bearing wear usually announces itself through noise long before the motor stops. With the power isolated at the switchboard, take the fan cover off and spin the shaft by hand to feel for roughness.
- A low growl or rumble that gets louder over weeks of running, or a high-pitched whine.
- A shaft that feels notchy, gritty or loose when turned by hand.
- Noise that began after the pump had a dripping shaft seal.
- A motor running hotter than it used to, or tripping on its overload.
Why both bearings and the seal go together
The drive-end and fan-end bearings have done identical hours, so a noisy one is a fair sign the other is close behind. Both are reached by splitting the motor, so pressing in a matched pair saves opening it up twice.
Moisture is a common cause of pump bearing failure. A weeping shaft seal lets water track along the shaft into the drive-end bearing first. Replace the seal in the same job or the new bearings can fail the same way: the PPP1500 mechanical seal is sold separately, and the PPP1500 service kit bundles the seal, bearings and run capacitor.
Same bearing set in other Onga pumps
This pair is also listed for the Onga Leisuretime LTP1100, Onga Pantera PPP550, Onga Pantera PPP750 and Onga Pantera PPP1100. Whatever the model, compare the new bearings against the ones you pull out of your motor before pressing them on. If anything looks different, contact us with a photo of the old bearings and the pump label. Kits for other models are under Onga service kits.
Before you order
Check the old part before fitting: match the bearings in your old motor.
