FREE UPGRADE FOR EJECTORS


01.11.2025 – 28.02.2026

Maximum precision fit and increased process reliability without additional machining or added costs. Order the high-quality, two-sided KNARR anti-twist protection during the promotional period – we will supply it at no extra charge compared to the standard ejector pin. See for yourself!

Two surfaces for clear positioning

The standardized, space-saving head shape of the ejector pin ensures its distinct position in the tool. Different surfaces on both sides  allow mounting only in the exactly desired position and prevent the distortion of the ejector at the same time . A circumferential bevel serves for pre-centering and helps to assemble easily and quickly.

KNARR offers the new anti-twist-lock system as hardened (39111), DLC-coated (39111DLC), nitrided-oxidated (39414) as well as HSS version (39555). In addition to the standard diameters, the lush range of dimensions also includes intermediate dimensions for repair purposes. In varying gradations, the ejector pins are available directly from stock up to a length of 800 mm.

Eight good reasons

Assembly only possible in one position

Repair dimensions with the same installation space

Circumferential bevel as pre-centring for easy and quick installation

Space-saving head shape allows close positioning of two or more ejector pins

No tilting achieved by double-sided surfaces

Pocket radius possible – no additional corner radius machining necessary

Easy machining of the chamfer possible

Different types for various applications


Anti-twist protection also for shouldered ejector pins

The advantages of a bi-lateral anti-twist lock can also be used with shouldered ejector pins. An HSS solution is offered as standard (396555), which provides even more wear resistance by means of its additional DLC coating (396599).
