SKF 2209 E-2RS1KTN9 Double Row Self-Aligning Bearing

SKF 2209 E-2RS1KTN9 is a double-row self-aligning ball bearing with a tapered bore and dual seals, designed to tolerate shaft misalignment while protecting against contamination. This 45x85x23 mm bearing features a 45 mm bore with a 1:12 taper (KTN9), an outer diameter of 85 mm, and a width of 23 mm. Sealed on both sides with 2RS1 shields, it provides contamination resistance suitable for dirty operating environments and reduces maintenance needs. The double-row arrangement delivers higher radial load capacity than a single-row equivalent, while still offering smooth rotation and forgiving alignment. Given its combination of tapered bore, two-side sealing, and self-aligning geometry, the 2209 E-2RS1KTN9 is commonly chosen in industrial applications where misalignment and exposure to dust, moisture, or debris are concerns.
