This is the genuine Maytronics acetal washer designed to seat on the wheel shaft of the Dolphin C6 CB robotic pool cleaner. Acting as a precision spacer and load-distribution component, it maintains correct axial alignment between the wheel assembly and the shaft, preventing metal-on-plastic contact wear during operation.<\/p>\n
The washer fits directly onto the wheel shaft, sitting between the wheel hub and the adjacent housing or retaining feature. By distributing bearing loads evenly, it reduces friction, prevents side-play in the wheel assembly, and protects both the shaft shoulder and the wheel bore from accelerated wear. Without it in good condition, the wheel will rock laterally, causing uneven drive and erratic pool-cleaning paths.<\/p>\n
Acetal (polyoxymethylene, POM) is the industry-standard engineering polymer for underwater bearing and spacer applications. It offers a low coefficient of friction against both metal and plastic, excellent dimensional stability in continuous water immersion, and resistance to the chlorinated and saline environments typical of residential and light-commercial pools. A genuine Maytronics acetal washer is manufactured to OEM tolerances, ensuring a precise fit on the C6 CB shaft diameter with no shimming or modification required.<\/p>\n
Replace this washer if you notice the robot’s wheels wobbling or clicking during a cleaning cycle, if the robot deviates from a straight climbing path on pool walls, or if you can feel lateral play in the wheel when the robot is out of the water and the wheel is rocked by hand. Worn or cracked washers can also cause accelerated wear on the shaft itself, so replacing the washer promptly protects higher-cost components.<\/p>\n
Aftermarket washers made from incorrect grades of nylon or polypropylene can swell in water, seize on the shaft, or wear rapidly \u2014 all leading to repeat failures. A genuine Maytronics washer is matched exactly to the shaft diameter and the clearance stack of the C6 CB wheel assembly, ensuring the service life and performance that Maytronics engineers to the platform.<\/p>","protected":false},"excerpt":{"rendered":"
