Amacoil-Uhing linear drive offers automatic shaft cleaning & lubricating option.
Amacoil-Uhing announced that its linear drives are now available with a combination shaft wiper/grease fitting for automatic cleaning and lubrication of the drive shaft. The shaft wiper is an O-ring made of specially formulated rubber which is mounted in a Delrin brand plastic fitting. One wiper is attached to each end of the drive unit. As the drive moves back and forth, the wipers push debris to either end of the shaft. When equipped with the grease fitting, the Delrin plastic fitting is made larger to accommodate the addition of the fitting and a felt ring which absorbs and evenly distributes lubricant around the shaft. The grease fitting is filled with a molybdenum disulfide-free grease which must be used with Uhing rolling ring linear drives.
