The flange bushing is required for the use of grinding and polishing tools on a grinding and polishing machine with a tapered shaft.

This makes it possible to change the tools used (contact disks, polishing rings, felt disks, flap grinding disks, etc.) extremely quickly on the grinding and polishing machine.Tools that have a flange bushing are simply pushed onto the conical shaft and, if necessary, aligned with a plastic or copper soft-face hammer. For dismantling, the soft-face hammer must also be used to remove the tools from the conical shaft with simple, light blows. Hits that are too hard can damage the flange bushing.Special feature:

In most cases, the flange bushing is mounted on a motor shaft located to the right of the motor. However, since there are also grinding and polishing machines where the motor shaft is on the left, a flange bushing with a left-hand thread must be used here. To tighten the nut of a flange bushing you need a size 85 open-end wrench or a corresponding pipe wrench. The web width of the tools to be clamped must be at least 10 mm. Otherwise, an additional side disk must be used. The normal flange bushings can only be used up to a maximum span width of 75-80 mm (approx. 110 mm wide). If a larger clamping width is required, the flange bushings can be used with a clamping width of up to 120 mm (approx. 150 mm wide).There are four different flange bushings, therefore there are four different positions on the tapered shaft.

Types:
39 / 41
40 / 42
41 / 43
42 / 44

FAPI-CONNECT flange sockets are available with either a left-hand or right-hand thread.
