SeaSense Roller Shaft with Grease Fitting - Heavy Duty Marine Boat Trailer Bearing Axle Replacement Part for Smooth Rolling & Easy Maintenance | Perfect for Saltwater & Freshwater Boating

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.
