Designed in Switzerland and meticulously crafted in Germany, the Swings Swiss Ceramic S-Steel is a breakthrough in skating performance. Central to the design are silicon nitride (Si3N4) ceramic balls, known for their low friction and exceptional durability. This innovative material allows skaters to reach higher speeds with less effort, making these bearings ideal for both competitive and recreational use. A distinguishing feature of these bearings is their contactless seal, which minimizes drag and protects against dust and moisture. This design extends the life of the bearing and ensures smooth rotation. The cage, made of glass fiber reinforced polyamide (PA 6.6), improves the stability and resilience of the bearing under load. Precision is key in the Swings Swiss Ceramic S-Steel, with a radial internal clearance of R14, which ensures an efficient and smooth roll. They are lubricated with Motorex Spindle Lube ISO VG 32, a high-performance lubricant that ensures consistent performance in varying weather conditions. The Swings Swiss Ceramic S-Steel bearing is field proven and has been thoroughly tested by our team skater and world champion Bart Swings. It has proven its superiority at prestigious events such as the Berlin Marathon in 2023. This bearing is not just a component; it is a premium choice for skaters who prioritize speed, precision and endurance.
