The SKF 6211-2RS is a deep groove ball bearing with double contact-type rubber seals (2RS), featuring a 55mm inner diameter, 100mm outer diameter, and 21mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for wet, dusty, or liquid-exposed environments (e.g., agricultural irrigation equipment, food processing machinery, offshore platforms). It handles radial and bidirectional axial loads, offering superior sealing, water resistance, and long service life.
