100 years ago a workshop for cutting and stamping tools was founded. From that
foundation Adolf Schnorr pioneered the development of series production of
Belleville disc springs.

Indexing in confined spaces
Elesa says that its new indexing plunger saves on
both space and costs usually associated with
installation.
The GN822 is a true mini indexing plunger at only
26.5mm long by 21mm knob diameter in its smallest
incarnation – even the largest is only 34mm x 25mm
diameter.
Fitment is simple; pull back the plunger knob to reveal a
hex head, and M8 or M10 thread suitable for mounting
even in thin sheet metal of 3.5mm or 4mm.
An AISI 303 stainless plunger provides accurate
positioning while the technopolymer knurled knob offers a
safe and solid grip during operations. The GN822 is
available in 2 executions –
without rest position and
with rest position, by pull

steel brushings are also

when installed in thin sheet.
