SKF 2204-E-2RS1TN9 Self Aligning Ball Bearing

SKF 2204 E-2RS1TN9 is a double‑row self‑aligning ball bearing with a cylindrical bore and seals on both sides (2RS1). It has a 20 mm bore, 47 mm outer diameter, and 18 mm width, yielding a compact 20×47×18 mm footprint. The bearing is specified with normal clearance (CN) and features a common outer race for both rows, enabling self‑alignment to accommodate shaft‑to‑housing misalignment without sacrificing performance. The 2RS1 sealing provides contamination protection and lubrication retention, reducing maintenance needs in imperfect mounting conditions. This model is part of SKF’s 2200 E 2RS1 family and is widely stocked by distributors, with the same bore, outer diameter, width, and dual‑seal configuration listed across major catalogs and OEM references. In practice, the combination of a cylindrical bore, dual seals, and two‑row construction makes the 2204 E‑2RS1TN9 a suitable choice for compact machinery where misalignment tolerance and reliable sealing are important.
