Dynamation - Tie Rods

New Clean-Profile Design

Mead’s new DM2 cylinders are constructed with an extruded body design rather than a tie-rod design, making these cylinders better suited for clean environments.

Dyna-Mation vs. HD Models

Dyna-Mation cylinders are designed to generate high performance in most applications. However, when operating conditions are severe, heavy duty models (HD Series) are recommended. The HD Series boasts the added benefits of a large hard-coated outboard rod bearing. The following profiles illustrate the differences of the rod end head in both types of cylinders:
