Hayward PVXH019SA Drive Gear Shaft Bearing | AquaNaut

OEM Hayward PVXH019SA Shaft Bearing is a high-quality replacement component made for AquaNaut 200, 250, 400, 450 and Poolvergnuegen 2- and 4-wheel suction cleaners. This dual-sided bearing plays a critical role in connecting rotational movement between the wheel hubs and steering bracket, allowing the cleaner to move fluidly across all pool surfaces. Its robust construction resists wear and chemical exposure, ensuring consistent cleaning performance even under frequent use. Installing a new shaft bearing helps restore balance, control, and effective debris collection.

• Supports Key Rotating Parts: Connects to both the steering bracket roller and wheel hubs, allowing coordinated rotational flow.

• Improves Traction and Turns: Helps the cleaner maintain smooth directional changes, improving overall surface coverage.
