Shafts FAQs

Have a question that you don't see here? Feel free to contact us with your recommendation for the FAQ section.

What is a stub shaft and when would you use one?

As the name implies, it is a short shaft located on each end of a dead-shaft idler. If you have stout framework, it is a great alternative to through shafts.  It has the advantage of lower cost and easier installation.

What are the different ways to mount an idler shaft?

A Dead-shaft idler shaft can be mounted to a frame via two tapped ends with a hole in each end of a sideframe.  Additional accuracy can be obtained by using a shoulder screw with a precision hole being machined in the frame and the end of the shaft.  Another mounting technique is a block mount with saddle which makes for easier removal.

Dead-shaft idler shafts can also be mounted to existing pillow block bearings when converting a live-shaft to dead-shaft idler roll.
