Bearing Protectors Grease Wheel Hub 1.98 w/ Bras Fit Trailer Boat x2

Bearing Protectors Grease Wheel Hub 1.98 with Brass for Trailer Boat x2

This pair of bearing protectors with brass fittings is a grease wheel hub accessory that keeps water out and grease in on trailer and boat axles.

Overview

These bearing protectors with brass fittings press into the hub to seal the wheel bearing cavity on trailers and boat trailers. Each grease wheel hub protector holds a reservoir of grease that feeds the bearings as they run, while the brass fitting lets you add grease without pulling the hub apart. Sold as a pair, they suit DIY boat owners and trailer owners who want to cut bearing service time.

Specs At A Glance

Good To Know

Q: How do I know these fit my trailer hub? A: Measure the bore where the bearing protector presses into the hub and confirm it matches the 1.98 inch size before ordering. A micrometer on the old protector or hub opening gives the most reliable reading.

Q: How much grease should I add after installation? A: Add grease with a standard gun until the bearing cavity is charged and stop when the piston or spring indicator moves outward. Overfilling past that point can force grease past the rear seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
