Wide Application: Bearing protectors are used for wheel hub grease cover bore with a diameter of 1.98 inches for boat trailers, snowmobiles, RV, ATV and utility trailers.
Weather Resistance: Chromed stainless steel bearing protectors have excellent corrosion resistance and rust resistance, suitable for saltwater or freshwater environments.
Prevent Leakage: Wheel bearing protectors keep the bearing grease from leaking out in high-speed rotation and high temperature environments, ensuring long-term lubrication of the bearings.
Maintain Lubrication: The spring piston design keeps the hub under slight pressure, and using a grease gun to lubricate bearings can solve the hub overheating issues and extend bearing life.
Dust Prevention: Dust covers effectively block water, dust, and debris from entering the bearing chamber, reducing bearing wear and corrosion.
