For performance mechanical engineering, packaging and handling applications, Treotham introduces igus’s lubrication-free and long-lasting drylin T linear rail guide systems with extremely wear-resistant sliding elements made of high-performance plastics, and offers fast delivery at a cost-effective price. The dimensions are identical to recirculating ball-bearing guides, so users can select a standard solution from stock.
The plastic sliding pads are injection moulded, the carriages are made of either zinc die-casting or an aluminium profile, and the production of all guide rails is carried out in an aluminium extrusion process with a hard-anodised finish. New, leaner assembly solutions at the factory in Cologne also ensure even more efficient assembly. The rails are available individually cut to the desired length and with no minimum order quantity, and then assembled with the appropriate carriage and elements.
The mounting holes match those of conventional recirculating ball-bearing guides, which allows engineers to take advantage of a quickly available and cost-effective alternative, enabling them to bring their machines to market faster. The tough linear carriages are available in four different installation sizes. An online fact check page that explains whether the drylin T solution will work for a given application can be found on the igus website. A comparison list of ball-bearing guides to drylin T guides with identical mounting dimensions is also provided.
In contrast to conventional recirculating ball-bearing guides, sliding pads made of high-performance plastics integrated in the carriages ensure a lubrication-free movement on the linear rails. Ball-bearing guides are susceptible to corrosion when used outside and therefore must be constantly oiled or greased, but plastic bearings can be used anywhere. They are equally resistant to heat and moisture, and water, dirt and swarf cannot damage them in many applications. The use of plastics makes the system lighter and silent.
Equipped with captive sliding elements made of iglidur J200, the system offers up to 50 per cent longer service life compared to the standard igus material used for linear guides. The bearing clearance of the carriages can be adjusted individually to a precision of 20μm.
