Full Product Description +

The Polaris 9-100-1108 Ball Bearing is a genuine replacement component designed for use in Polaris pressure-side pool cleaners, including the Polaris 380, 360, and 340 models. This bearing is installed inside the cleaner’s wheel assemblies and allows the wheels to rotate smoothly with minimal resistance during operation.

Proper wheel rotation is essential for consistent cleaner movement, balanced traction, and even pool coverage. As bearings wear over time, they can become rough, corroded, or seized due to constant exposure to water, debris, and mechanical load. When this occurs, cleaners may move unevenly, struggle to climb walls, or place additional strain on internal drive components.

Replacing worn ball bearings helps restore smooth wheel operation and ensures the cleaner moves as designed across pool floors and walls.


Why the Ball Bearing Matters

Wheel bearings directly affect cleaner movement and drivetrain health.

Why this matters:

  • Allows smooth, low-resistance wheel rotation

  • Improves cleaner traction and mobility

  • Reduces strain on gears and drive components

  • Helps maintain proper cleaning patterns

  • Extends overall cleaner service life

Worn bearings can cause dragging, uneven movement, and premature wear on other cleaner parts.


Designed for Polaris Pressure-Side Cleaners

The Polaris 9-100-1108 Ball Bearing is manufactured to OEM specifications for precise fit and dependable performance in compatible Polaris cleaners. It is designed specifically for use in the wheel assemblies of the Polaris 380, 360, and 340 pressure-side models.

Using a genuine Polaris replacement ensures correct dimensions, material quality, and durability under normal operating conditions. Aftermarket bearings may not provide the same smooth rotation or long-term reliability.

Always confirm cleaner model compatibility before installation.


Service-Friendly Replacement Component

Ball bearings are considered wear items and are commonly replaced during routine cleaner rebuilds or when addressing mobility issues. Installation is straightforward once the wheel assembly is removed and can typically be completed during standard cleaner maintenance.

When replacing bearings, it is recommended to inspect related components such as wheels, axles, tires, and gears. Replacing worn components together helps restore factory-level performance and prevents repeat service issues.
