Latching lever with ball knob

With indexing levers GN 215 shafts can be turned through a predetermined angle and positively locked. To index, lift the lever against spring pressure from serrations (one hand control). Limiting the indexing angle can be achieved with two dowels (sketch). The bushing is connected to the shaft via keyway. The location flange is bolted to the machine with two socket head cap screws (M 5). The lever, via the location pin, provides the connection between shaft and location flange. The serrations are protected from swarf and similar particles by the cover. This cover can be inserted by hand (elastic segments engage into a groove) and removed with a screw driver.
