Design and application advice
Linchpins at the end of shafts
This is one of the widest spread applications. In response, Rübig has supplemented the standard series, offering an even wider range of sizes than those listed in DIN 11023.

Linchpins in the center of the shaft or tube
When using linchpins on tubes it's necessary to pay special attention to the maximum surface pressure. The allowable values are ..
max. 350 N/mm² for DIN Linchpins up to 8 mm diameter;
max. 420 N/mm² for DIN Linchpins 8mm- 10mm diameter; and
max. 250 N/mm² for Commercial Linchpins
.. and should not be exceeded. We also offer hardened pins upon request which can handle pressures up to 850 N/mm².
Linchpins on rectangular tubes and special applications
The RÜBIG Formclip was especially designed for securing rectangular tubes. Simple closures, transport hedges etc. can be constructed cheaply and conveniently using formclips.
