Linear drive offers automatic shaft cleaning and lubrication

Uhing linear drives now offer a combination shaft scraper/grease-fitting option for automatic cleaning and lubrication of the driveshaft. The option removes excessive grease, dust, and dirt from the shaft while the drive is running and simultaneously assures adequate shaft lubrication. Accumulated debris can be wiped away with a cloth. In most applications, the scrapers can be used without the grease fittings to clean the shaft while the drive runs. The grease-fitting combination is recommended for heavy usage applications and when shaft rpms exceed rated speeds (1,000 rpm for Model RG drives; 1,500 rpm for Model RS drives).

The shaft scraper is a specially formulated rubber O-ring that is mounted in a Delrin plastic fitting. One scraper is attached to each of the end bushings on the drive unit. When equipped with the grease fitting, the plastic fitting is made larger to accommodate the addition of a felt wiper ring, which wicks oil out of the grease and applies a thin oil film to the shaft as the drive runs.
