Dover Flexo Electronics' precision-machined aluminum idler rollers and tension rollers are manufactured to the highest quality and can be used solo on your press or web machinery or with any stationary shaft, shaft-end tension transducers or UPB transducers including DFE’s Model C, or UPBH and SUPB type transducers.
If you’re planning to install shaft-end transducers at a new position
in your machine’s web path, maybe you’d like to save time
and trouble by ordering a dead-shaft idler roll for the
installation at the same time.
DFE has been making and supplying reliable precision aluminum idler rolls and tension rollers for
customers on an as requested basis for a long time. Now you can order
aluminum dead-shaft idler rolls as standard items with short lead times.
These precision-machined rolls are manufactured to the highest quality
and can be used solo on your press or web machinery or with any stationary
shaft, shaft-end tension transducers or UPB transducers including DFE’s
Model C, UPBH and SUPB type transducers.

Custom roll surface finishes are available. Shafts are TGP steel with

DFE has decided to formally offer idler rolls because of the company’s
success and experience over the past two decades with its popular Tension
Roll® transducer, a dead-shaft idler roll with tension sensors built
into each end; and also because DFE has been providing idler rolls informally
to customers who have requested them over the years.
