| Two parallel guide shafts
(8) - connected to each other by two end elements (2) form
the body of the linear unit COPAS. The guide table (7), guided
on shafts driven by an ACME thread or ball screw spindle (5). |

| Bearing |
Spindle bearing: fixation bearing
(pin side): double-row, sealed angular contact bearing combined with
axial grooved ball bearing.
Fixation bearing (loose) single-row, sealed grooved ball bearing
Guide table: 4 sections ball bushing with pressed seals. |
