Full Product Description +
The Polaris 9-100-1108 Ball Bearing is a genuine replacement component for compatible Polaris 340, 360, and 380 cleaner wheel assemblies. The Polaris 340 is a suction-side cleaner; the 360 and 380 are pressure-side cleaners. This bearing supports smooth wheel rotation 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 340, 360, and 380 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 listed for the wheel assemblies of Polaris 340, 360, and 380 cleaners. Confirm part number 9-100-1108 in your cleaner’s parts diagram before ordering.
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.
