The Tru-Trac has special tapers (similar to a crown pulley) on the outer edges of the tracker which cause the drum of the Tru-Trac to pivot about an internal, vertical pivot axis. The internal central pivot is perpendicular to the belt and this results in the tracking action always being on the same horizontal plane as the belt. For tis reason the Tru-Trac works equally well with reversible and shuttle conveyors.

The bearings are mounted in the bearing housing in both ends of the drum, to provide support for the roller drum over its full length. This ensures concentric vibration-free rotation. Each Tru-Trac uses a pair of 6017 2RS Bearings to facilitate the design (internal movement of the shaft within the inner sleeve) and, therefore, are well within their RPM and load specifications. this allows conveyor belts with speeds exceeding 7 m/s to be tracked. The centre pivot is unique and simple, consisting of a stainless steel pin within a solid mild steel centre shaft.

The combination of dissimilar material in the centre pivot eliminates the likelihood of seizure. As an added precaution a nickle anti-seize compound is added and the whole unit is seal welded for life. The drum of the Tru-Trac is rubberised in natural rubber, ensuring excellent contact and traction between the surfaces of the belt and tracker. We will also apply specific coatings, as per client"s requirements, where necessary.

The bearing housing, including front and back seal, has been specifically developed for the entire Tru-Trac product range, ensuring effective sealing in adverse conditions. An adjustable mounting bracket has also been developed, allowing the Tru-Trac to be easily adapted to most stringer configurations. This same bracket enables the tension and, if necessary, the tracking angle to be adjusted.
