Our pulleys are fabricated with AS3678 grade 250 plate for the shells and end disks, except where pipe sizes are available. We offer API 5LB grade pipe which has a higher UTS than grade 250 plate
All welds conforms to AS1554.1 SP. We also offer welding to AS1554.5 for special high stress applications.
Shafts are designed to AS1403 and material is generally AS1442 grade 1045, however we can provide other grades such as AS1444 grade 4140 upon request.
Our ultra heavy duty forming rollers are CNC machined from AS1442 1045 grade billet steel for the shells and AS1444 grade 4140 for the shafts.
Our rollers are assembled using SKF bearings and a unique sealing method to eliminate moisture and contaminate ingress..
VeyTech design and manufacture “heavy duty” idlers and rollers for impact zones and heavy tension areas where high failure rates occur.
These idlers and rollers have designed & engineered bearing housings and shafts complete with SKF seals and bearings to give superior performance and longevity.
Impact idlers have autoclaved natural or FRAS rubber with soft design edges and are cylindrically ground to guarantee smooth and balanced operation with the integrity of the rubber. The result is improved wear life and performance reducing down-time due to idler and roller failures
RUBBER DISC RETURN ROLLERS
Veytech's Rubber Disc Return Idlers are manufactured with durable natural or FRAS rubber discs positioned at regular intervals along the roller to effectively eliminate conveyor belt carry back build up. This is done by breaking up the material on the return side of the conveyor belt which is normally concentrated in the centre of the belt. The rubber discs are bunched together at either end of the roller to provide support and protection to the belt edges.
