Slip yoke with dust cap offWhat a Slip Yoke Does
The slip yoke is an important component of any drive shaft assembly. The slip yoke assembly (pictured on the right) is what allows drive shafts and PTOs to flex or “slip” with their given application. The slip yoke is also essential for allowing u-joints to rotate properly with the drive shaft.

Slip yokes come in a large assortment of dimensions to accommodate for the infinite amount of applications that require a drive shaft. The term “slip yoke assembly” is used interchangeably with the terms “slip yoke” and “slip”. The only difference among these terms is that a “slip yoke assembly” contains a dust cap, which is usually supplied with any slip yoke that is sold as an individual part and essential when installed in a drive shaft.

Why Machine Service, Inc. is the Slip Yoke Expert
The most important element of any slip yoke is to keep them lubricated during the life cycle of the drive shaft. Lack of lubrication or dirty lubricants causes one of the most common types of failure in a driveline because the lack of lubricant causes severe stresses to occur along the driveline, which in turn will cause severe damage to the application.
