We offer several specialty idlers for unique and challenging material-handling applications. The offset roll design of our grain idler offer protection for even the lightest belts; the spiral idler is designed for sticky material handling; the Tufkon idler is designed for abrasive, corrosive material handling; and the wobbler idler is designed for belt training.
Our grain idler design provides an offset roll with equal length configuration, which effectively assures zero roll-gap for protection of even the lightest belts. Grain idlers are available with 5” and 6” diameter rolls, 24” through 72” belt widths, and in 20 degree, 35 degree and 45 degree designs.
Our spiral idlers are designed to perform in even the stickiest applications. Their unique corkscrew design works to clean the conveyor belts and helps to control belt training problems associated with installations handling sticky material. Key benefits include:
- Self-cleaning, self-training spiral idlers solve many material build-up problems
- Resists abrasion, corrosion, and gouging
- Positive contact seals keep dirt and dust out, while keeping grease in
- Simple removal and replacement
- Smooth, catenary idler curve prolongs belt life
- Urethane spiral outwears neoprene and natural rubber
- Unique double-spiral design produces a positive cleaning action that continually cleans both belt and idler surface
Spiral idlers are available in belt widths of 18” to 48”.
Moving abrasive, corrosive bulk materials by conveyor requires components that can withstand the harshest environments. Our Tufkon idler is an innovative solution that addresses some of the most difficult challenges in these environments.
The Tufkon roll uses a 1020 carbon steel inner shell covered with a .500” high-density polyethylene outer sleeve. Roll ends are manufactured from non-corrosive, glass fiber-enforced, thermo composite with 6205 series (CEMA C) and 6305 series (CEMA D) double-sealed ball bearings. The end disc totally encapsulates the shaft and remains stationary during operation, eliminating the possibility of rolls locking due to materials becoming wedged between the roll end and the frame.
The coated frame is resistant to most solvents and acids, making it suitable for mining and industrial applications handling corrosive materials. This application-specific idler helps minimize downtime and reduce maintenance costs through its demonstrated significant extended useful life.
Our Tufkon idler roll with coated frame is suited for the following applications:
- CEMA C installations with 5” or 6” diameter rolls in belt widths ranging from 18” to 60”
- CEMA D installations with 5” or 6” diameter rolls in belt widths ranging from 24” to 72”
Our wobbler idler is a special return training idler designed to train your conveyor belt. Its unique design – a steel roll centered on a 60 mm ball bearing – pivots when the conveyor belt moves off center and guides it back to allow for a more efficient operating conveyor.
The wobbler idler also solves material buildup problems. Most training idlers have complex frames which accumulate material, causing roll jams and resulting in de-training and damage to the belt. The wobbler idler is held in place by two simple brackets, with no framework to collect material. Lubrication can held be accomplished from either side.
For sticky material or adverse weather conditions, the wobbler idler is available with a ¼” urethane cover that eliminates material buildup on the surface of the idler. The wobbler idler is available in belt widths from 18” to 60”.
