SeaSense Roller Shaft with Grease Fitting - Heavy Duty Marine Bearing System for Boat Trailers & Docks - Perfect for Smooth Rolling & Long-Lasting Performance

After being frustrated with the standard roller shafts that are difficult to install, I decided to give this one a try. It’s easy to install and the c clips seem more secure than the press on caps that standard roller shafts use. The only improvement would be the holes for tbe grease fittings could be located further toward the middle so that the grease would stay inside the roller.
