304 Stainless Steel Hinge Head Piece Threaded Protective
Precision CNC-turned pressure bar rods with hardened surface treatment, engineered for high load-bearing capacity, wear resistance, and dimensional stability—ideal for industrial machinery, hydraulic/pneumatic systems, and automation equipment transmission applications.
| Parameter | Key Details |
|---|---|
| Base Materials | Alloy Steel (4140/4340): High hardenability and fatigue resistance, suitable for heavy-duty pressure transmission rods; Carbon Steel (C45E/S45C): Cost-effective option for general-purpose pressure bars; Stainless Steel (304/316): Corrosion-resistant for humid/chemical environments; all materials support post-hardening processes |
| Surface Hardening Treatments | Nitriding (surface hardness ≥650 HV, hardened layer 0.1–0.5mm, no dimensional distortion); Induction hardening (local hardness 58–62 HRC for stress-bearing sections); Hard chrome plating (thickness 0.02–0.1mm, hardness ≥850 HV, wear/corrosion resistance); all treatments comply with industrial rod component standards |
| Processing & Precision Tolerance | CNC precision turning (single/multi-spindle for mass production), centerless grinding (for roundness accuracy), polishing, threading (M4–M30 ISO 6g threads); tight tolerances: Diameter tolerance h5–h6 (±0.005–±0.01mm); straightness ≤0.005mm/m; concentricity ≤0.008mm; surface roughness Ra 0.2–0.8μm (smooth surface reduces friction with mating parts) |
| Size Range & Customization | Customizable dimensions: Diameter 3–150mm; length 50–3000mm; rod profiles (cylindrical, stepped, tapered, threaded ends); optional features (keyways, grooves, flange collars, heat-shrink fit sections); supports custom CAD/STEP file designs for non-standard pressure bars |
| Compatibility | Fits hydraulic/pneumatic cylinder piston rods, industrial press pressure bars, automation equipment transmission rods, and machine tool guide rods; compatible with linear bearings, seals, and mounting brackets |
