The inserts can be replaced separately when worn without changing the base body. \"Reversible\" indicates that the same insert can be mounted in two opposite orientations — for internal or external gripping — without changing the jaw.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eFor Ø 400 mm — what is the clamping range for these jaws?\u003c\/summary\u003e\n\u003cp\u003eThe reversible top jaws for Ø 400 mm chucks clamp workpieces within a diameter range that depends on the jaw travel and the mounted configuration. As a general reference, the jaws cover a range of approximately ±30–40% of the nominal chuck diameter. For very small diameters (workpieces \u0026lt;Ø 20 mm on a Ø 400 mm chuck), consider smaller jaws or collets.

When the top inserts are worn or when you want to mount inserts made of a different material (e.g., soft inserts for delicate workpieces), you unfasten the screws and replace only the inserts without having to buy the complete jaw set. Replacement inserts available separately.
