US Digital offers a wide variety of standard HubDisk assemblies (optical encoder disk attached to an aluminum hub) to aid with mounting onto a shaft. Encoder disks may also be ordered as a stand alone item (see the Disks page). The rotary encoder disks are made from 0.007'' thick Mylar polyester film and the material allows for a -40C to 100C temperature range. The disk on the HubDisk assembly comes attached with the emulsion side up when the disk text is correct reading. HUBDISK-1 consists of a precision machined aluminum hub fastened to a 1'' diameter optical encoder disk (DISK-1). One set screw is used to fasten the hub to a shaft. The HubDisk assembly is available with bore sizes ranging from 2 mm to 10 mm. All HubDisk assembly bores are held to a very tight tolerance defined by US Digital Technical Bulletin, Shaft and Bore Tolerances TB1001.
