As part of our ongoing continuous improvement efforts, US Digital is implementing a change related to the production of our 5/16" (.313), 8mm (.315), 3/8" (.375), and 10mm (.394) HUBDISK assemblies. We are adding a low strength threadlocker to the set screw during our assembly process to assist in securing the set screw in the hub during transportation. This will aid in the set screw retention of these specific hub sizes; ensuring the retention is sufficient and avoid the potential of them backing out of the hub assembly during transit. This change does not affect form, fit or function.
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.
US Digital® designs and manufactures rotary absolute and incremental optical encoders, inclinometers and other precision motion control components used in a variety of applications including industrial automation, medical, robotics, textiles, renewable energy and more. US Digital® is ISO 9001:2015 certified.
