Frequently asked questions
Reversible top jaws Ø 160 mm — what do "top" and "reversible" mean?
"Top" jaws means that the jaw is composed of two parts: the base body (hardened steel) that moves in the chuck slides, and the top insert (the actual jaw, made of soft or hardened steel) screwed onto the base body. The inserts can be replaced separately when worn out without changing the base body. "Reversible" means that the same insert can be mounted in two opposite orientations — for internal or external gripping — without changing the jaw.
For Ø 160 mm — what is the clamping range of these jaws?
Reversible top jaws for Ø 160 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 <Ø 20 mm on a Ø 160 mm chuck), consider smaller jaws or collets. Customer support in Italian available.
Can the top inserts be replaced separately?
Yes — this is the main advantage of the top jaw construction. When the top inserts are worn or when you want to mount inserts of a different material (e.g., soft inserts for delicate workpieces), you unscrew the fastening screws and replace only the inserts without having to buy the complete set of jaws. Replacement inserts are available separately. Customer support in Italian available.
