  9. Is there a cutting charge for igus® linear rails?

    There are no additional costs for cutting linear rails at igus®.

  10. Where do you see a requirement for the all polymer telescopic slide (NTP-27-18-150)?

    This new slide offers a great solution to industries where infection control and wash downs are important, the entire slide is manufactured from polymer and requires no grease/oil to operate, this also allows the slide to be washed down with no negative impact on the performance of the slide.  Also, this slide will be a great option for industries where weight saving is important like aircraft & Robotics as the slide offers up to 64% weight reduction compared to metallic alternatives.

  11. Is this slide available in different polymer materials & sizes?

    At the moment we offer one standard size option which can be produced in 3 different colours, but if you require a specific length or material to suit a certain industry, for example an FDA approved material or vertical burn approved material igus can offer this solution with a tooling charge.

  12. What is an igus® hybrid roller bearing?

    An igus® hybrid roller bearing utilises 2 key features, our dry sliding elements, and also a polymer roller to reduce friction.

  13. What benefits do the igus® hybrid roller bearings have over tradition ball bearing rollers?

    The benefits of a hybrid roller are exceptionally low friction due to the polymer roller, and the usual igus® benefits such as maintenance free and modular design.

  14. What sizes are the hybrid roller bearings available in?

    We can supply these to suit shafts and rails with 10,16, and 20mm diameter.

  15. Does igus® offer a stainless-steel version of the hybrid roller bearing?

    igus® do offer cast and machined stainless versions of the hybrid rollers, also aluminium.

  16. Does igus® have an FDA compliant hybrid roller bearing?

    Not yet as a standard product however if you have a requirement please give us a call on 01604 677240 or email us on sales@igus.co.uk to discuss the requirement as we may be able to custom design one.

  17. How easy is it to change the liners of the hybrid roller bearings?

    Currently this is not possible however there are always developments in the drylin® department so an interchangeable one may be an option eventually.

  18. What material is the liner of the hybrid roller bearing?

    The liner is our iglidur® J material.

  19. What material is the standard housing of the hybrid roller made from?

    Zinc is the standard material however we have options for both aluminium and stainless steel. 

  20. Can you use igus® hybrid rollers in both lateral and horizontal applications?


    Yes, you can use our hybrid rollers in a few orientations as well in combination with different design rollers, examples above.

  21. Do the igus® hybrid roller bearings use rollers inside of ball bearings?


    They use sliding elements and a roller – image above, there is an option for a ball bearing one if needed.

  22. Is drylin® T interchangeable with traditional ball bearing systems?

    Yes it is! Our drylin® T has the exact same dimensions as the traditional recirculating bearing systems making it easy to change to drylin® T.

  23. Is drylin® T adjustable?

    Some of the carriages we offer for drylin® T allow for manual adjustments and offer adjustments with clearances too.

  24. Can you wash drylin® T down?

    Yes you can! As the rails are made from hard anodised aluminium, wash downs are fine. If you are unsure, give us a call
