xiros® is a trademark name by igus® and it is the name we give the umbrella of products that fall under the ball bearing umbrella. Historically, igus® was known for sliding bearings rather than the rolling balls found within a ball bearing, but after many years of material development and testing, the xiros® product group was launched in to the market. Within this range there are deep grove radial ball bearings, a range of axial ball bearings, thrust washers, slewing rings, labelling and conveyor rollers and we offer bespoke parts with integration of other components to keep costs and component count to a minimum.
xiros® bearings are offered by igus® and selected by our customers in order to solve application in either a cost effective way and / or a way that provides longer life over a plain bearing or metallic solutions. xiros® ,being made of polymer races and stainless, glass or polymer balls require no additional lubrication. We find that we have thousands of customers in the Food and Packaging, Automotive, aerospace and special purpose machine building industries.
xiros® is made up of several components. If we just focus on the radial deep grove ball bearings, they are made up of a moulded inner race, moulded outer race and a moulded cage. We then assemble with either a stainless steel, glass or polymer ball depending on the application. The design of the assembly is so that we are able to snap the bearing assemblies together and yet they still offer huge strength under axial and radial loading and can’t become dismantled in application. All moulding and assembly happen in our factory in Cologne alongside our plain bushing, spherical and linear bearings being moulded and assembled. We can make bespoke solutions in high volumes using this same method and for lower quantity solutions we can machine using our plastic rod / stock bar material. There is no MOQ.
Many of our xiros® materials are FDA-approved, find out more on the website.
xiros® bearings are being used in myriad industries and applications, some examples are:
- bicycle wash system – low absorption means powerful operation
- pellet stove – high temperature properties ensure no melting
- pool cleaner – deep groove ball bearings ensure steady operation
- labelling machines – self-lubrication means smooth running
- ball bearing races on both sides of the ball bearings
- ball bearing cage
- different ball bearing types: stainless steel, glass, polymer
The beneficial properties include:
- underwater applicability
- high media resistance
- high and low temperature applicability: -100°C to +150°C
- metal free or metal-detectable
- predictable service life
We calculate the lifetime of the roller through the xiros® ball-bearings lifetime. This can be easily calculated using the xiros® life-time calculator. Click on the link.
The bearings can be easily removed from the roller tube and replaced.
We can supply a bespoke solution to suit your application- please discuss with our expert to determine the optimum solution. Call us on 01604 677240 or visit the website for more information.
We can supply shafts in all materials, from aluminium to stainless steel. Shafts can be supplied as a standard length or machined to suit with additional threads/keyways etc. There is a configuration tool to help. Click here.
Yes We Can – we would need to discuss the application in detail with you, looking at the overall speeds and loads to determine if a longer roller can be produced. Please ring the office on 01604 677240 to discuss options!
Please click the form here and we will respond within 24 hours to discuss your application with you. We can visit physically or arrange a virtual meeting. You can also call the usual number 01604 677240 to be put through to our specialist.
Due to this manufacturing process, different rules apply to the measurement as well as the installation compared to metal or ceramic ball bearings.
The outer ring of the polymer ball bearings has a conical shape. This simplifies the installation in a suitable housing (with the narrow side first). After press-fit into a housing machined to a H7 tolerance, the bearing clearance is reduced. Therefore, the ball bearings must be measured over the entire width; starting at an angle of 90° from the injection point

The DIN 625 specifies the dimensions for single row radial deep groove ball bearings. It is the best known standard in the rolling bearing sector.

- It depends on the bearing but when the following issues occur, the bearings need tobe changed:
- The bearing clearance caused by wear has reached an unacceptable level, for example, when the shaft “sags”.
- the cage is worn and in danger of falling out.
- the bearing rings are broken due to excessive impact forces.
- the running surface of the bearing rings are visibly damaged.
- the ball bearing is blocked, for example, due to coarse dirt.
- the balls (glass) are broken.
- “previously unheard of noise emissions” occur.
- no more bearing clearance is present due to deposits on the balls.
