SKF 2211E-2RS1TN9 Self-Aligning Ball Bearing Double Row

SKF 2211E-2RS1TN9 is a double-row self-aligning ball bearing with seals on both sides (2RS1) designed to compensate for shaft misalignment while supporting radial loads in rotating equipment. It features a 55 mm bore, a 100 mm outer diameter, and a width of 25 mm, and it is configured as a double-row bearing with a common outer race, which simplifies mounting and helps accommodate mounting tolerances. The TN9 suffix indicates SKF's standard clearance variant for this model, and multiple suppliers note a glass-fibre reinforced PA66 cage for added rigidity under cycling duty while maintaining light weight; the lubricant is grease as indicated in SKF data sheets. The combination of dual seals and the self-aligning geometry helps resist contamination and reduces the risk of binding when eccentricities are present, making this bearing well-suited for applications where precise alignment cannot be guaranteed and smooth rotary operation is essential.
