Hydraulic & Pneumatic Applications

Hydraulic & Pneumatic applications rely on high pressures, controlled movement, and precision sealing between components. Even minor surface imperfections or dimensional variation can disrupt airflow or lead to internal leakage. Precision ground bar stock is essential for producing components that maintain tight fits and smooth, low-friction motion under dynamic operating conditions.

The consistent diameter and superior surface finish of ground bar stock supports the manufacturing of parts that require close-clearance fits, such as pistons, rods, and spools. These parts must slide smoothly within cylinders or housings without introducing wear or pressure loss over time. Straightness and roundness are especially critical to maintaining concentricity and proper alignment in high-cycle applications.

Typical pneumatic applications include:

• Cylinder rods and piston shafts requiring low-friction surface finishes
• Valve components where dimensional uniformity affects pressure control
• Guide pins and alignment shafts for air-actuated tooling and assemblies
• Sealing surfaces in pneumatic actuators and regulators
