Thanks to its unique combination of properties, Stanyl® was selected by SKF Group, for a new generation of deep groove ball bearings, designed to cut energy consumption by at least 30%.
The improved energy performance has been achieved through a combination of enhancements involving the bearing,internal geometry, a new low friction grease and a new polymer cage. The resulting reduced friction lowers operating temperatures, improves lubrication conditions, and allows the bearings to deliver a longer service life.
These technologically advanced ball bearings are produced by SKF Group, one of the leading global suppliers of rolling bearings, seals, mechatronics, services and lubrication systems. They are designed for light to normal load applications. Typical examples include electric motors, pumps, conveyors and fans. They can also be used in other applications such as gearboxes and compressors.
Richard Damiens, Global Purchasing Manager for the SKF group, said: “Stanyl’s material performance contributes to achieving a range of end-user benefits. These include lower energy consumption, easier development of higher efficiency machinery, higher speed rating of the bearings and reduced operating temperature. As a consequence , bearing life can be extended. Thanks to this combination of properties, customers will benefit from a lower total cost of ownership.”
Andreas Weinmann, Account Manager at DSM Engineering Plastics says: “The specific requirements for the deep-groove ball bearings cages include high stiffness under high temperatures, low creep, high fatigue resistance, chemical resistance to the applied lubricants and low wear.
Stanyl TW200F6, a 30 % glass fibre reinforced PA 46 grade from DSM Engineering Plastics was selected for this application. Key reasons are high wear resistance, stiffness, strength and toughness. This combination allowed optimized internal geometry, low noise, low torque, long-lasting lubrication and new polymer cage design. Stanyl also offered the best overall system cost.”
Stanyl® high performance polyamide is the material of choice for demanding applications such as these. Stanyl® is able to deliver greater durability: extreme wear and abrasion resistance, as a result of its unmatched high fatigue, ductility and creep resistance thanks to its 70-80% crystallinity levels. Other key benefits include greater design freedom, as a result of the material’s 150% higher stiffness, strength and creep resistance at temperatures of 150-220°C when compared to other PAs and PPAs; lower system costs, lower weight and less noise compared to metals.
