The sliding movements of components, i.e. a piston in a tube, risk metal-to-metal contact that will damage and score the surfaces and eventually cause seal damage, leakage and component damage. To prevent this, piston and gland should have a brass bearing surface or precision guide elements such as wear rings, wear bands, guide rings or bearings.
The greater the side load forces, the stronger the wear ring material must be. Wear rings should last longer than the seals as they are the only things stopping expensive damage to the cylinder.
