Basco Dust Cover Bearing Protector

These 45mm trailer, caravan, and boat bearing buddies are designed to protect wheel bearings by maintaining constant grease pressure inside the hub. Featuring a stainless steel coated finish for improved corrosion resistance, they help prevent water and dust from entering the bearings, even when submerged, making them ideal for marine and heavy-duty trailer use. Installation is simple—remove the existing dust caps, tap the bearing buddies into place, and fill with grease via the integrated grease nipples. Supplied as a high-quality pair complete with dust cover caps, they suit most trailer hubs with a 45mm (1-3/4") internal diameter and are an effective solution for extending bearing life and improving reliability.
