I am familiar with products from igus and know the necessary inner and outer diameters, materials, requirements etc.
I know the environment variables of my application and would like to calculate the service life of my ball bearings.
I need more information on xiros polymer ball bearings with regard to materials, types and advantages.
I need an individual, custom-made special part that deviates from the DIN standard for my special application.
xiros polymer ball bearings to DIN 625 do not need any additional lubrication, are corrosion-resistant (if glass or plastic balls are used) and, during operation, are extremely quiet. This makes them a cost-effective alternative to metal ball bearings. Made from a mixture of tribo-polymers, the xirodur polymer components are light, resistant to chemicals and non-magnetic. This ensures that they can be used safely in the areas of medicine, food processing, drive technology etc.
The plastic of our xiros ball bearings consist of a mixture of standard polymers, solid lubricants, fibres and filaments, whereas the balls are typically made of glass, plastic or stainless steel. The balls are located in a cage, which can consist of our own xirodur B180 material, polyamide (PA), polypropylene (PP) or polyetheretherketone (PEEK). Please see our catalogue to find further combinations of materials in addition to technical specifications.
Ball bearings belong to the family of rolling element bearings. Moving between an inner ring and an outer ring, rolling elements reduce rotational friction and absorb radial and axial loads. In most applications, one ring is rigid and the other is attached to the rotating assembly such as a hub or a shaft made of steel. When a ring rotates, the balls, which are fixed in place inside a cage, also begin to rotate.
Because the balls roll, they have a much smaller coefficient of friction than two flat surfaces that slide against each other. Due to the smaller contact surface between balls and rings, the ball bearings tend to have a lower load capacity for their size than other kinds of rolling bearings. However, they can tolerate a certain amount of misalignment of the inner and outer rings.
Benefits:
Polymer ball bearings are used in up to 36 guide rollers and supersede their conventional metal counterparts. They ensure uninterrupted operation.
This mobile bike wash system uses two igus slewing ring ball bearings for the bearings of the washing brushes, which work without problems despite difficult conditions.
Despite being used under water, the installed radial deep groove ball bearings made of polymer work without any failures. This is due to their self-lubricating and corrosion-free properties.
Despite extremely difficult conditions, the radial deep groove ball bearings from igus used in this mechanical drive unit of a pellet stove, which is responsible for the currentless transfer of pellets into the combustion chamber, work as required.
Here, you can find further successful solutions of our customers with xiros bearings made of polymer.
They do and here's how. Due to the absence of external lubricants, the xiros polymer ball bearings are highly suitable for applications that involve contact with water or are even completely under water. Because they are lubrication-free, corrosion problems and a short service life are things of the past.
Our ball bearings are put through their paces in the industry's largest test laboratory anywhere in the world.
