Made from high performance polymers, iglidur® plain bearings are wear-resistant tribo-polymers improved by precise additions of strengthening materials and solid lubricants. Tested thousands of times, igus® engineers developed and tested 267 new plastic compounds each year. The finely tuned combination of plastic matrix, strengthening components and solid lubricants in every single tribo-polymer results in an individual properties profile in each case.
In more than 12,000 individuals tests a year on over 200 test rigs in the igus® test laboratory, all materials are thoroughly tested. The findings go into a unique knowledge database on the tribology of maintenance-free plastic plain bearings. This database enables us to select the ideal iglidur® plain bearing for our customers depending on the application and to calculate its anticipated service life.
This is dependent on the application. Mostly, igus® plastic bearings do not need to be stronger than metal bearings, but they will outlast them. Please email email@example.com for some technical help or ring 01604 677240.
Yes, we can machine parts to your drawing, send us the enquiry via this form and you will get a quote by return, usually the same day, certainly within 24 hours.
The iglidur® plain bearings are designed to be pressed into a housing (with an H7 tolerance) The bearing will have a nominal size for the outer diameter. They are then secured by the press-fit. Please be aware that the outside diameter of the bearing is, depending on the nominal size, about 0.1 to 0.25 mm larger than the housing in the non-pressed state. The inner diameter will reach its final dimensions and tolerances when pressed in.
iglidur® J3 is an extremely low wear material. It gives up to three times more wear resistance than standard iglidur® J , however is yellow and sometimes customers need to have a material which is invisible within their application or certainly hidden. iglidur® J3, which is now available in black means that customers can have a material that is extremely wear resistant and allows for the bearing to be hidden.
All of our bearings run dry as you know, but sometimes extreme applications require an extra seal. Rubber seals in abrasive environments do not work very well, they wear out very quickly, however felt seals act as a filter and a seal when running dry, keeping out those abrasive particles. This allows for the bearings to last much longer in these really extreme environments, agriculture being one of them.
As you know, our iglidur® bearings are injection moulded. The materials are homogeneous and this means that you get the same performance throughout the wall thickness. However, even with this predictable nature customers are demanding more high tech solutions to their reduction in downtime. So, we have designed and are now producing iglidur® bearings with a wear detecting system inside the material. This allows the bearing to have a set amount of wear and when the bearing reaches this, it sends a signal to a module which alerts the customer that the bearing is due to be inspected. The signal is not sent at a failing point but it will need to be looked at soon.
The tribo coating, or iglidur® coating is a tribologically optimised polymer in powder form. This can be applied to metallic surfaces through a process called powder coating. The tribo coating powders offer excellent friction and wear properties. This new process allows protection on heavily used surfaces from wear and tear – without using any additional components.
The different iglidur® coatings differ mainly in their temperature resistance, their sliding or wear properties and their colour. If you require the material data, this can be found in our material data sheets.
We subjected our iglidur® coating materials to more than 10,000 different application-oriented tests to analyse the wear behaviour in the most diverse application scenarios. This enables us to select the optimum and most cost-effective material for your application.
Our overhead conveyors allow component sizes up to 3 x 1 x 1 metre.
Yes absolutely! We carefully mask off the areas that will not be coated according to your requirements. For larger quantities, we manufacture appropriate devices that reduce process costs to a minimum.
The iglidur® coating layer can be applied with a thickness of approx. 60-120 µm. Different coating thicknesses are possible depending on the material and surface quality of the parts to be coated.
The surface must be cleaned and be free of dust, dirt or liquids. We can carry out the necessary processing steps for you should you require it
The ‘cross cut’ according to DIN EN ISO 2409 shall enable an estimation of the adhesive strength of coatings, i.e the painted surface. The test method is thereby not used to measure the adhesive strength. For this purpose, the trigger test according to DIN EN ISO 4624 shall be applied.
The rating is based on indicators from 0 to 5, with 0 representing the best rating “very good”. All tribo coating materials (IC01, IC03, IC06) fulfil the criterion 0.
