Grease ball bearings? Not necessary with xiros®

What makes the igus ball bearings so special? Thanks to the polymers used, all xiros plastic ball bearings run permanently maintenance-free without additional lubricants. 

► Inner and outer race: 
The suitability of a xiros plastic ball bearing is determined by the materials of the two raceways. Our low-friction ball bearings are made of high-performance polymers with different material properties, which means that they can be used in many applications and service life can be maximised. 

► Ball bearing cage:
The cages of our plastic ball bearings are perfectly matched to the materials of the outer and inner races in terms of chemical and temperature resistance.

► Ball bearing balls: 
In addition to balls made of stainless steel, balls made of glass or plastic are also used. Glass balls should be selected when 'metal-free' and 'chemical-resistant' are required properties. Polymer balls result in particularly lightweight ball bearings. The stainless steel version is especially cost-effective and temperature-resistant.

Lubrication-free

Cost-effective

Direct from the manufacturer

The product range of xiros plastic ball bearings is particularly distinguished by the wide variety of types and materials. Small ball bearings are used in model making and medical technology, among others. Our ball bearings successfully serve a wide range of applications - special parts manufactured according to customer requirements are also part of the product range.

Predictable service life

Thanks to extensive tests in the xiros test laboratory, the service life of igus ball bearings can be accurately predicted even under difficult conditions - even for individual applications.

Particularly lightweight

Metal ball bearings are robust - and heavy. xiros ball bearings offer the perfect alternative for a wide range of applications, as plastic ball bearings are lightweight, reliable and durable.

Plastic ball bearings are often used in the automotive industry and aerospace engineering. Wherever lightweight is important, our light plastic ball bearings are ideal.

Corrosion-resistant

Plastic ball bearings have a decisive advantage over those made of metal: They are extremely resistant to corrosion. Even when used in corrosive environments, the xiros ball bearings maintain their smooth running and long service life - with low maintenance requirements.

Temperature-resistant

Thanks to the specially developed high-performance polymers for extreme operating conditions, our ball bearings are suitable for low and high temperatures, depending on the application. Due to these specifications, expensive special lubricants for metal bearings are not necessary. The performance of these polymer ball bearings has been tested and confirmed in numerous tests in the xiros test laboratory, even in extreme cold conditions down to -100°C.

For applications with high heat loads, igus offers high-temperature ball bearings with thermal resistance up to +150°C for long-term use.

FDA-compliant

Ball bearings made of FDA-compliant plastics are used wherever components come into contact with food or are used in sterile areas.

Thanks to the FDA-approved plastics developed by igus, which also work completely without additional lubricants, xiros ball bearings are ideal for applications in food, beverage and medical devices.

Non-magnetic and current-isolating

Wherever metal-free properties are required, non-magnetic and current-insulated plastic ball bearings are the first choice. The xiros range includes both pure plastic ball bearings and variants with glass balls.

The product range also includes conductive and detectable polymer ball bearings.

Resistant to chemicals

The chemical-resistant plastics developed by igus enable xiros ball bearings to operate flawlessly even when in contact with aggressive chemicals. The stated durability and calculated service life are based on data from our test laboratory.

The chemical-resistant plastic ball bearings do without expensive special lubricants that are needed in applications exposed to aggressive chemicals.
