SKF rolling bearings must be adequately lubricated to operate reliably. The lubricant is required to reduce friction, inhibit wear, protect the bearing surfaces against corrosion and may also be needed to provide cooling. This section describes:

The above diagram shows these selection criteria and the related bearing ratings and static safety factor, which are described in detail in the relevant sub-sections. Which selection criteria you should use depends on the operating conditions of the bearing:

The size of a bearing must be sufficient to ensure that it is strong enough to deliver the required/expected life under defined operating conditions. the two main criteria that can be used for determining appropriate bearing size are:

A: xiros® is a trademark name by igus® and it is the name we give to our polymer ball bearing product line. 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. We currently offer deep groove radial ball bearings, axial ball bearings, ball transfers, & slewing rings, as well as labeling and guide rollers.

The drawing shows the relationship between principal operating conditions, application requirements and various aspects of a bearing arrangement’s design. The lists are not comprehensive and you may have to consider other factors and interrelationships, such as cost and availability, when striving to obtain a robust and cost-effective solution.

Does your application have a distinctive design, a need for a custom component, or extreme environmental conditions that your ball bearings are exposed to? Request a custom design with the ability to upload a CAD file and describe your unique application requirements.

A: Many of our xiros® materials are FDA-approved, for example our B180 and A500 materials combined with 316 stainless steel balls.

A: 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.

A: We can supply shafts in all materials, from aluminum to stainless steel. Shafts can be supplied as a standard length, or machined to suit with additional threads/keyways, etc. Check out our drylin linear shafting product pages!

A: All of the xiros® bearings provide high wear resistance, but each material and design will offer a unique service life. Use the service life calculator to find out more, or contact igus to discuss your application further!

The pellet stove Gravity allows the electricity-free transport of wood pellets into the combustion chamber through a mechanical drive unit. Two self-lubricating plastic ball bearings with the xiros® A500 material are used in the mechanical drive unit, ensuring that the wood pellets are fed to the combustion chamber via a roller.

A: xiros® bearings are continuously tested in our lab at our worldwide headquarters in Germany. We apply multiple loads, speeds, and sequences to detrmine the products' life expectancy for a range of sizes and use this data to build our online expert system. The expert system allows you to approximate the lifetime of the product based on the provided application details.

xiros® plastic ball bearings require no external lubrication, are corrosion resistant (when used with glass or plastic balls) and operate quietly, making them a cost-effective alternative to steel ball bearings. Comprised of a tribopolymer blend, the all-plastic components are lightweight, chemical resistant and non-magnetic and can safely be used in medical or food processing environments. While the xiros® plastic material consists of a blend of base plastics, solid lubricants, fibers and filaments, the balls are typically made of glass, plastic or stainless steel.  All bearings are also rigorously tested in our state-of-the-art test lab. Use the xiros® service life calculator to quickly determine a ball bearing suitable for your application, and then calculate its expected service life. Have a unique design or need for a custom ball bearing in a specific shape, material or quantity? Click here to request a custom design with the ability to upload a CAD file and describe your unique application requirements.  Why choose xiros plastic ball bearings?  Learn more about the unique design and the advantages.

They influence many performance characteristics of an application and its parts, and do so in various ways depending on the operational state, such as at startup or in normal operation, when steady-state conditions have been reached.

In addition to the SKF bearing rating life, there are key factors you must consider when putting together the SKF bearing specifications for an application, including:

The SKF bearing selection provides a straight forward step-by-step approach that shows the general relationship between each step.

A: xiros® is made up of several components. If we just focus on the radial deep groove ball bearings, they are made up of a molded inner race, molded outer race, and a molded 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 they can't become dismantled in the application. All molding and assembly happen in our factory in Cologne, Germany. We can make custom solutions in high volumes using this same method, and for lower-quantity solutions, we can machine using our plastic bar stock material.

A: xiros® bearings are offered by igus® and selected by our customers in order to solve application issues in a way that provides longer life over plain bearing or metallic solutions, while also often being cost-effective. xiros, being made of polymer races and stainless, glass, or polymer balls, require no additional lubrication. Many of our successful applications are in the food and packaging, automotive, and medical industries. We have versions for chemical resistance, FDA-compliance, high-temperature, ESD, underwater, and even non-magnetic with the use of glass balls.

With the Sleevematic labeling machine, labels are cut from the roll one at a time and then attached to the bottles. Once a roll of labels is depleted, it needs to be replaced by a new one without stopping the entire plant. Here the so-called "buffer conveyor" is used as a film storage, in which Krones employs xiros® plastic guide rollers from igus®.

The relationships between the temperature and power loss of components within an application is complex and these factors, in turn, have interdependencies with many others such as bearing sizes, loads and lubrication conditions.

A: The most unique aspect of the product group is the materials used to create them. The special materials allow the ball bearings to be used in specialty applications where other solutions fail prematurely. The materials are completely maintenance-free, requiring no external lubrication, are lighter weight, and in many cases, can offer a cost savings.

Each SKF bearing type has characteristic properties that make it more or less suitable for use in a given application. This section provides information on what to consider when selecting a bearing arrangement and the types of bearing to use with it. It also provides guidelines on choosing bearing types to satisfy specific demands of an application, such as accommodating available space, loads, misalignment, and more.

A: xiros bearings are being used in many industries and applications. Some examples include x-ray and medical devices (non-magnetic and FDA-approved), pellet stoves (high temperature properties), pool cleaners (corrosion-resistant and low moisture absorption), and labeling machines (low friction and lightweight).

When selecting SKF bearings for any purpose, ultimately you want to be certain of achieving the required level of equipment performance, and robustness, at the lowest possible cost. There are key factors you must consider when selecting SKF bearings for an application. For helping you evaluate these key factors, we provide recommended SKF bearing selection, as well as supporting information.

A: Due to the 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 an 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.

A: 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. Deflection will also be an important thing to consider here.
