Polaris Vac-Sweep 380 / 360 and "Trade Grade" TR35P / TR36P Pressure Cleaner Shield, Bearing (9-100-7011)
The shield bearing is a replacement part made by Polaris. The same high-grade materials were used for the original factory part. Making this a genuine OEM product.
The purpose of these shield bearings is to retain lubricant and prevent contamination from entering the bearing raceways. This can impede or disrupt the bearing from turning or rotating. This would then cause an issue in the cleaner’s ability to maneuver its way around the surface of your pool.
