xiros® deep groove ball bearings

The single-row xiros deep groove ball bearings are polymer ball bearings in accordance with DIN 625 and belong to the family of rolling bearings as the most well-known of many types. What are radial ball bearings? They are largely used to absorb radial loads - at high speeds. In exceptional cases, they are also suitable for the absorption of small axial forces. This is made possible by the rolling elements that lie close against the running grooves of the bearing. Are you specifically looking for deep groove thrust bearings? Take a look here.

Like other rolling bearings, our lubrication-free and maintenance-free bearings consist of four components. However, different polymer versions of the two rings - the inner ring and the outer ring - are offered in order to do justice to the most varied of customer requirements . The bearing cage must also be adapted to the respective ambient conditions. Our ball bearings are fitted with stainless-steel, glass or polymer balls.

Outer ring & inner ring

The suitability of a xiros bearing according to DIN 625 is crucially determined by the materials of the two rings. They are made of igus tribo-polymers in order to maximise their service life and minimise friction. There are diverse materials to choose from. They allow different values for application temperature, media resistance and price. The table of materials provides exact information.

The balls

The ball materials differ most significantly. In addition to steel, glass or polymers are used. This produces a large difference in mass, which in turn affects inertia, weight and chemical resistance. Stainless-steel balls are cost-effective and resistant to chemicals but are also the heaviest type. Glass balls are used to give a metal-free solution. They are also very resistant to chemicals and have an average weight. Polymer balls have significant advantages in terms of weight, mass and quietness during use. Depending on the polymer used, the balls can have excellent chemical resistance.

  • ES stainless steel (1.4401)
  • GL glass (soda-lime glass)
  • PAI plastic "PAI"
  • POM plastic "POM"

The cage

The material of the bearing cage must also match the application. These materials are also very different as regards their resistance to chemicals and temperature fluctuations/extremes. Within the xiros bearing product range, the cages are already perfectly matched to the materials of the inner and outer rings.

Further types of our radial deep groove ball bearings:

  • Convex rollers which can run directly on a profile
  • Profiled rollers, e.g. for thread/cable guidance
  • Axial and slewing ring bearings for the absorption of axial loads.
  • Multi-axis bearings for linear and radial movements
  • Ball bearings designed e.g. for installation in tube ends (also for guide rollers)
  • Double-row bearings for absorbing higher forces
