Belting 101: Belt Tracking

Date September 2016 • in Belting

Having a belt properly track on the machine is a key factor that effects the belt life. PTFE belts are different than other lower temperature belts and ensuring that the belt properly tracks is vital to its performance. PTFE belts are different than other kinds of belting for three primary reasons.

The first difference is the stretch of the belts. PTFE coated belts are typically made from fiberglass yarns, which have very low stretch properties, causing a greater need for precise belt tracking. The second difference is the thickness of the belt. Most belts made by AFC range from .010 to .050 inches thick. The thinness is desired for more rapid heat transfer, but the thinner the belt is, the more fragile it will be, further increasing the importance of belt tracking. The third major difference is the slippery surface of these belts. PTFE is known for its low co-efficient of friction and non-stick surface.

Because of the importance of proper belt tracking, there have been various tracking system designs created to ensure that machines are able to efficiently track their belts. These tracking methods can range from continuous edge guides, active tracking mechanisms, and buttons to name a few. The tracking method used depends on the tracking mechanisms of the machine. With the various tracking methods available, our technical team has developed a Belt Tracking manual to benefit all end-user of our belts. We also offer continuous technical support to partner with our customers to help them solve their problems.
