GURTEC GMBH

GURTEC’s Heavy Mining Idler Roller is setting a new standard for high speed mass transportation and life cycle costs. Our highly automated manufacturing line utilises a flow forming process for extremely round tubes and an end forming process to round shell edges and integrate concentric bearing houses to the roller shell body, avoiding the need for welding.

A roller with a solid shaft as standard, hollow shaft as option Bearing seats formed as an integral part of the shell, the opposing bearings are therefore accurately aligned The formed bearing holders improve bearing performance leading to lower failure rates Dimensions: Roller diameters 152 – 219 mm (6” to 8-5/8”) Shaft diameters up to 62 mm (2-1/2”) Bearings 6306, 6308, 6310, 6312

A flow formed roller shell and hollow formed shaft Option for an increased wall thickness at the middle of the shell for reduced shell deformation and increased fatigue life Extremely low TIR with a accurate and constant shell thickness significantly reduces vibration and increases service life Dimensions: Roller diameters 159 – 219 mm (6-1/4” to 8-5/8”) Shaft diameters up to 82 mm (3-1/4”) Bearings 6308, 6310, 6312

Available as frames only or fitted with rollers as idlers We supply trough carry, impact, training, and disc return fixed frames in a wide range of sizes for belt widths from 350 mm to 3,500 mm (14″ to 138″) Frames are either galvanized or with a painted surface finish All our frames provide minimal gaps between rollers and are designed to counteract material build-up Our frames are designed to maintain an optimum conveyor belt profile for low rolling resistance, excellent belt support, good belt guidance and long belt life

Trough or flat carry frames available (including transition frames) Combinations range from single roll to 5 roll designs Dimensions: Belt widths from 350 to 3,500 mm (14” to 138”) Various trough angles available

Jackdown frames in 3, 5, 6 or 10 roll arrangements Retractable frames Other special loading frames available – for example impact roller cassettes Dimensions: Includes Jackdown, retractable and other special impact arrangements Belt widths from 350 to 3,500 mm (14” to 138”) Various trough angles available

Includes flat return and multi-roll vee returns Dimensions: Available is single roll, 2, 3, 4 or 5 roll configurations Belt widths from 350 to 3,500 mm (14” to 138”)

Development structure is available from 1,050 to 1,400 mm (42” to 55”) Maingate structure is available from 1,400 – 2,000 mm (55” to 78”) Supplied complete with garland or fixed frame idlers Suitable for floor or roof mounting Dimensions: Available as development and maingate structure Belt widths from 1,050 – 2,000 mm (42” to 78”)

Positive action training frames in all configurations Side guide rollers orientate the frame and help ensure the belt tracks centrally on the conveyor Dimensions: Available in all configurations for both carry and return frames Positive action helps keep the belt aligned with the center of the conveyor

Our garland rollers are connected to each other with flexible links and fixed to the conveyor frame with suspension links Free movement in the direction of the belt travel has also a positive influence on the self-centering of the belt easy to replace by lifting the idler set from the mounting hook
