Ball Lock Ejector Punches Heavy Duty, Inch, XCN Coating

These heavy-duty, inch-dimension ball-lock ejector punches are used in progressive punch press tooling where stable ejector actuation and repeatable alignment are critical. The ball-lock head geometry helps maintain positive engagement during the ejection stroke, reducing the risk of misalignment under high cycle loads.

• Industrial stamping dies: Suitable for lock-driven ejector designs that need dependable cycling while stripping formed parts and managing debris in forming stations.
• Forming station die sets: Works well when ejector components must stay locked through frequent compressive and lateral forces; inch-coded dimensions support straightforward integration with established tooling layouts.
• Service-life focused tooling: The XCN coating is intended to reduce wear and support consistent surface performance where punches see extended contact and sliding during ejection.

Choose the variant with your required tip shape code (H/J/K/L/N/O/R/V/X/Y/Z) and the corresponding shank and length range to match your cavity/core ejector requirements.

The provided product specifications describe dimensions and coating (not the underlying steel grade or exact heat treatment). As such, the material selection guidance below focuses on the XCN coating performance role and how it affects tool behavior in service.

• XCN coating: Typically selected to improve wear resistance at the contact surfaces involved in ball locking and ejection motion, supporting more consistent punch performance over repetitive cycles.
• Wear vs. toughness trade-off: Coatings generally increase surface hardness/tribological performance; however, the underlying steel toughness (if applicable in your spec) remains essential to prevent damage under shock loads from high-speed ejection.

For definitive hardness (e.g., HRC), substrate steel equivalency (e.g., SKD61/H13), and heat treatment state (quenched & tempered, nitrided, etc.), confirm the bill of materials or material datasheet for the specific series code and size you will run.

Correct selection starts with matching the ejector punch to your tooling’s mechanical envelope and ball-lock interface. Use the D (shank dia.) range of 37–125 in to fit the guide/support area for your punch press die set, then choose the L (length) coded inch range of 250–450 or 275–450 based on required protrusion and safe travel.

• Tip engagement geometry: Select the Tip Shape code (H, J, K, L, N, O, R, V, X, Y, Z) to match the mating ball-lock pocket and ejector path in your die design.
• Interface dimensions: Validate P (0.376–1.251 in), W (0.062–1.083 in), and R (0.007–1 in across the available ranges) against your cavity/core features.
• Tolerance/fit considerations: Ball-lock systems are sensitive to fit; keep your drawing tolerances aligned with the chosen size set and verify clearance for locking and unlocking under load.

Tip shapes and the Jektole group (J4, J6, J9, J12) are configuration-dependent; fixed dimensions vary by selected code.
