[Lifetime Warranty] C80 C-80 Turbine Bearings Replacement - Compatible with Polaris 180 280 280 TankTrax, Vac-Sweep 20 Pool Cleaners | Pack of 4

C-80 / C80 Turbine Ball Bearings

Key Features

• Low-Friction Performance: Engineered with precision-ground internal ball bearings to ensure the turbine and drive axles spin freely, maximizing the cleaning speed and climbing power of your pool vacuum.
• Corrosion-Resistant Stainless Steel: Manufactured from high-grade stainless steel specifically treated to resist the corrosive effects of salt, chlorine, and acidic pool water environments.
• Double-Shielded Protection: Features a reinforced design to help prevent sand, silt, and fine debris from entering the bearing races, which is the primary cause of mechanical seizing in pool cleaners.
• Universal Drive System Fit: Designed to the exact physical dimensions of the Polaris C-80 standard, ensuring a perfect "drop-in" fit for both the turbine assembly and the large drive wheels.

Replaces / Cross-Reference Part Numbers

• Primary Part Number: C-80, C80.

Compatibility & Fitment

This bearing is a standard replacement part for Polaris pressure-side automatic pool cleaners. Key compatible models include:

• Polaris 280: Fits the turbine assembly and all three large drive wheels.
• Polaris 180: Compatible with the legacy 180 turbine and wheel axles.
• Polaris 280 TankTrax: Direct fit for the specialized TankTrax drive system bearings.
• Vac-Sweep 280: Standard replacement for all Vac-Sweep 280 series units.
• Note: These bearings are typically used in pairs. Most Polaris 280 cleaners require 8 bearings for a full wheel and turbine rebuild.

When to Replace

• Audible Grinding or Screeching: If your cleaner makes a high-pitched metal-on-metal sound while moving, the internal balls in the C-80 bearing have likely rusted or flattened.
• Cleaner Moving in Circles: If one side of the cleaner is moving slower than the other, it often indicates that a wheel bearing has seized, creating drag.
• Turbine Stalling: If the cleaner doesn't move at all despite high water pressure, the turbine bearings may be jammed with grit, preventing the drive shaft from spinning.
• Excessive Wheel "Wobble": If the large wheels have significant side-to-side play, the internal race of the bearing has worn down and can no longer hold the axle steady.

Installation Tips

• Check the Axle First: PRO TIP: Before installing the new C-80 bearings, inspect the plastic wheel axle for wear. If the axle is "grooved" or worn down, the new bearing will still wobble and fail prematurely.
• The "Snap" Fit: When installing into a wheel or turbine housing, press firmly on the outer race of the bearing only. Pressing on the center or the shield can damage the internal ball alignment.
• No Lubrication Needed: These bearings are designed to be lubricated by the pool water itself. Do not apply grease or oil, as these substances can attract sand and cause the bearing to seize faster.
• Test for Smoothness: After snapping the bearing in, spin the wheel or turbine by hand. It should spin silently for several seconds. If it stops immediately, the housing may be warped or the bearing is not seated level.
