Heavy-duty construction for tough applicationsThe PSV roller is designed to handle the toughest applications and environmental conditions with high reliability. The PSV rollers off er the highest quality and maximum load capacity and are particularly suited for conveyors that operate under very diffi cult conditions, where working loads are high, and large lump size material is being conveyed.

Each roller consists of a heavy gauge steel tube carrying surface, with pressed steel end-caps that are precision welded together to form a monolithic structure of exceptional strength that guarantees maximum precision and minimum imbalance on the overall roller diameter. A rotational test is performed on 100% of rollers.

Sealed for lifeA quality roller is characterised by its effective sealing system. Scrupulous research tests and, above all, the practical plant experience in the most variable environmental situations, has made it possible to develop a particular sealing that guarantees optimum bearing performance.

The bearings are lubricated with long life lithium based water repellent grease which off ers high stability under various atmos-pheric conditions. The quantity of grease is suffi cient for the life of the roller eliminating lubrication and maintenance costs. The bear-ing is protected, on the external and internal

side of the roller, by seals which withhold the lubricant and at the same time prevent the entrance of contaminants.

30,000 working hoursThe unique design of the totally hermetic seal consisting of inner seal, triple labyrinth, outer rubber V-ring and centrifugal self cleaning chamber protects the bearing against possible entrance of contaminants, such as rain, dirt, dust, etc. with a minimum of friction drag. Life projection is 30,000 working hours or more depending on the load.

The ideal static and dynamic balance of the PSV roller eliminates vibrations and bearing hammering and thus guarantees trouble- and noise free running even in high speed applications year after year. The rollers are galvanized to resist corrosion.

Low starting and rolling resistanceThe PSV roller has low starting and rolling resistance for minimal power consumption and low cost operation. All rollers are

The PSV roller meets the toughest demands and many types of industries such as mining, quarries, power, cement etc. rely upon its heavy duty con-struction and long wear life for reliable conveying.

tested to assure that, at a certain speed, the friction drag is not higher than the recom-mended value.

Low friction drag, reduces energy require-ments, keeping production high and total operating costs low.

Support framesSturdy cross-angle support frames have the roller brackets accurately jig welded in place. Support frames can be supplied straight or with the end brackets tilted a few degrees in the direction of conveyor belt travel to aid the throughing rollers in centering the belt. Longitudinal slots for mounting bolts facilitate alignment of idlers. Also available are suspended “Garland” sets.

The Garland set consists of rollers connected by chain links. The suspended design is flex-ible increasing the ability to absorb dynamic stresses. It´s especially suitable for high speed operations carrying large size material.

A triple barrier sealing system keeps grease in and contaminantsout for maximum life.

The Garland designs ability to absorb dynamic forces extend the life of both conveyor belts and rollers.

Return rollers with rubber discs mounted is used to prevent materialbuild up and mistracking. The rollers can also be delivered with a seamless rubber sleeve.
