The second tip for cylinder maintenance
Uneven wear of the rod is often a result of misalignment. Side load causes the rod to rub on one side of the bearing, which can prematurely wear the bearing, seal(s) and rod itself. In most cases, a corroded and damaged rod can be re-chromed and/or polished to refinish it. If the rod can’t be repaired, it can be manufactured by any cylinder repair shop. Before re-installation, it would be wise to remedy the problem causing the damage in the first place, or you will find yourself in the business of changing the cylinder often.
