Tolerance compensation

The new adjustable steel ring, which reduces assembly times and simplifies maintenance, consists of a solid M-Tech S support ring onto which two semicircular shim ring segments of the type M-Tech L are glued. While the thickness of the support ring is 6mm, the peelable segments have a total thickness of 3.2mm and can be peeled off 64 times in thicknesses of five hundredths of a millimetre.

With a total thickness of 9.2mm, the so-called thickness deviation in the ring is only a maximum of 0.03 mm over the entire ring surface. With 630mm, the diameter is far greater than that of the one-piece rings used up to now for tolerance compensation.
