4-Pack 1.980-Inch Stainless Steel Boat Trailer Bearings with Protective Bra

4 Pieces 1.980 Boat Trailer Bearing Stainless Steel SS with Protective Bra This bearing is constructed from stainless steel, making it suitable for use in salt water environments due to its resistance to rust.The bearing measures 1.980 inches at its base and is designed to fit most 4 and 5 bolt hubs.It features a pressure system that maintains approximately 3 psi of internal pressure within the hub, helping to prevent water from entering when submerged.This pressure helps extend bearing life and allows for greasing between full hub repacks.The unit includes a movable piston with a black indicator ring.When the hub is fully filled with grease, the piston extends outward about 1/8 inch.If the piston can be pressed inward or moves easily, additional grease should be added.A grease fitting located in the center of the piston allows for easy re-lubrication.An automatic pressure relief mechanism prevents over-filling and protects the inner seal from damage.The outer barrel and internal components are made of stainless steel for enhanced corrosion resistance.To maintain performance, inspect bearings and seals before installation.Replace any damaged, corroded, or pitted bearings and inner seals are intact and operate smoothly on the spindle.Clean out old grease and from the hub prior to assembly.Fill the hub completely with a multipurpose, grade No.2 lubricant during reassembly.Avoid using heavy, fibrous greases or mixing different grease types.
