This insert bearing is secured onto the shaft by means of an eccentric locking collar, with the inner ring extended on one side. Sealing is provided by a stamped steel washer fitted with a rubberized lip. The catalog designation is SA 211, dimensionally and constructionally equivalent to SKF YET 211. The eccentric locking collar allows the bearing to be fixed at any angular position on the shaft, which simplifies alignment during mounting. The extended inner ring on one side supports the locking mechanism and shaft engagement from that end. The stamped steel washer with rubberized lip seal protects the internal raceway and rolling elements from dust and contamination while retaining lubricant within the bearing housing.
