Needles- rollers - Import export

KIS needle roller bearings are ideal for applications that require space-saving rolling bearings with high load carrying capacity. We offer needle roller bearings in both radial and axial designs as well as in combined designs. In bearing technology, cylindrical rolling elements are referred to as needles if the rolling element diameter is ≦ 6 mm and the ratio of rolling element diameter to rolling element length gives a value Dw/lw ＜ 1:3. Radial needle roller bearings are intended exclusively for use as non-locating bearings. The given axial displacement path for bearings with an inner ring allows axial movements between the shaft and the housing. If necessary, wider inner rings are available to allow larger axial displacement paths. Our combined needle bearings are characterised by particularly high precision and efficiency. By integrating both bearings into one unit, combined needle roller bearings are often easier to press in and easier to handle than individual solutions.

Hydraulic operated Rotational speed of brush: max. 150 RPM Can be adjusted by hydraulic pump – brush will be lifted to operation position by hydraulic cylinder and keep same pressure against the belt

Standard Catalogue Product Range Pulley Diameters up to 800mm (32”) Belt widths up to 2,800mm (110”)

Wide range to meet even the toughest demands includes a standard range for compact light duty and medium duty pulleys as well as engineered class pulleys for heavy duty applications Available in all sizes with masses up to 45 tonnes as drive, tail and bend pulleys Advanced design process incorporating Finite Element Analysis ensure the pulleys are designed to world’s best practice Dead-shaft, wing and deflection wheels for high angle conveying are also available

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

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”)

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”)

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

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

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

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

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

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.
