Amacoil/Uhing recently introduced the Elasto-Ring washer for use with U-Clip quick release shaft collars. Elasto-Ring installs by hand with no tools required and is designed to assure easy removal of the U-Clip collar.
The Elasto-Ring washer snaps onto the end of the U-Clip collar. When the U-Clip is in place, the Elasto-Ring is against the spool flange – between the flange and the U-Clip. If back pressure starts to build, it is absorbed by the Elasto-Ring which flexes against the U-Clip collar. This cushions the U-Clip and prevents a build up of back pressure. The quick release feature is designed to assure fast, easy, one-handed removal of the U-Clip and Elasto-Ring.
Elasto-Ring washers are available in the same ten sizes as U-Clip collars for use on shafts with diameters ranging from 8 mm to 35 mm. Made from durable, heat resistant rubber, Elasto-Ring washers are long lasting and will not deteriorate from heat generated by friction coming from the rotating spool flange.
Meant for most basic spooling processes, U-Clip shaft collars with Elasto-Ring washers may not be suitable for some high-speed packaging and converting operations. For these applications, Uhing EasyLock shaft collars feature adjustable clamping force which eliminates play and is designed to assure that the reel and shaft start and stop together. For maximum holding force, both U-Clip and EasyLock collars must be used on case hardened and precision ground smooth shafts with no threads.
