HUBDISK-1 Product Description

Restriction of Hazardous Substances

HUBDISK-1 consists of a 1 in. diameter optical encoder disk (DISK-1) mounted on a precision machined aluminum hub. The disk is made from 0.007 in. thick Mylar filme and a set screw is used to secure the hub to a shaft. The HubDisk assembly is available with 14 bore sizes ranging from 2mm to 10mm. All hub bores are held to a tight tolerance defined by US Digital Technical Bulletin, Shaft and Bore Tolerances TB1001.

US Digital offers a wide variety of standard HubDisk assemblies (optical encoder disk attached to an aluminum hub) to aid mounting onto a shaft. Encoder disks may also be ordered as stand-alone items. The rotary encoder disks are made from 0.007 in. 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 right-reading.

PRODUCT CHANGE NOTIFICATIONS

Title Date Description Download
HUBDISK-1 Packaging Change Notification - PCN 6297 4/30/2018 As part of our ongoing continuous improvement efforts, US Digital is implementing a change to the packaging of our 1-inch Hubdisk assemblies.

We are replacing the current plastic tube packaging with a 25-count plastic tray. The tray is a two-piece design with snap-on lid and anti-static coated for ESD sensitive environments. This change is designed to enhance the ease of handling for our customers, easy removal of the individual hubdisk, and protection against potential damage due to long-term storage of hubdisk assemblies.

This change does not affect form, fit, or function of the final product.		 Download
Hub Set Screw Production Change - PCN 5367 7/20/2015 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. Download
