1. Hardened alloy steel guide ring eliminates over travel and provides support to reduce wear from off center loads.
2. High strength composite bearing support for off center loads without damaging the cylinder walls.
3. Hardened and chromed piston reduces wear and corrosion.
4. Heavy-duty return spring provide quick retraction times.
5. High strength alloy steel body is precision machined to reduce wear and features a baked enamel finish for durability and corrosion protection.
6. Industrial U-cup style seal prevents costly leaks.
7. Standard coupler provided with dust cover.
