9-100-1108 Wheel Ball Bearing Replacement

Key Features

• Precision Glide Technology: Specifically engineered with high-tolerance internal ball bearings to ensure the drive wheels rotate with zero resistance, allowing the cleaner to maintain consistent speed across the pool floor.
• Dual-Shielded Debris Protection: Features a reinforced metal shield on both sides of the bearing to prevent fine sand, silt, and plaster dust from entering the races, which is the leading cause of bearing seizure.
• Corrosion-Resistant Stainless Steel: Manufactured from premium-grade stainless steel that is fully compatible with saltwater systems, high chlorine levels, and varying pH balances without rusting.
• High-Load Durability: Designed to support the weight of the cleaner head and the torque of the drive system without warping or flat-spotting the internal balls over long-term use.

Compatibility & Fitment

This bearing is designed specifically for the wide-track wheel systems used on Polaris belt-driven and gear-driven models. Key compatible models include:

• Polaris 380 / Vac-Sweep 380: Standard replacement for all wheel axles.
• Polaris 360 / Vac-Sweep 360: Fits the 360 series (which does not require a booster pump).
• Polaris 3900 Sport: Direct fit for the high-performance P39 series.
• Polaris 480 PRO: Compatible with the professional-grade 4-wheel drive system.
• Polaris ATV: Fits the specialized All-Terrain Vehicle model drive wheels.
• Note: These are not the same as the C-80 bearings used on the Polaris 280. Ensure your model is listed above before installation.

When to Replace

• Wheels "Dragging" or Stuck: The cleaner is moving slowly because the internal balls have rusted or are jammed with grit.
• Significant Wheel Wobble: If the wheels lean to the side or vibrate excessively, the bearing race has worn down and lost its structural integrity.
• Screeching or Grinding Sound: Audible metal-on-metal noise indicates the lubrication has failed and the bearing is failing.
• Belt Failure: On 360/380 models, seized bearings can put excessive strain on the drive belts, causing them to snap or slip.

Installation Tips

• The "Clean Seat" Rule: PRO TIP: Before pressing the new 9-100-1108 bearings into the wheel, use a damp cloth to wipe the plastic wheel hub. Any sand trapped between the bearing and the wheel will cause the bearing to sit crooked.
• Apply Pressure Evenly: When installing, press only on the outer metal rim of the bearing. Pressing on the center shield can collapse the bearing and ruin it before it’s even used.
• Check the Axle Nut: Ensure the wheel screw/nut is tightened enough to remove wobble, but not so tight that it "pinches" the bearing. The wheel should spin for 5–10 seconds when flicked by hand.
• Water Lubricated: Like most pool bearings, these are designed to be "wet-lubricated" by pool water. Do not apply oil or grease, as they will attract dirt and shorten the lifespan.
