This insert bearing is secured on the shaft by means of an eccentric locking collar, with the inner ring extended on one side to accommodate the locking element. The bore diameter (d) is 30 mm, and the weight is 0.31 kg. The further dimensions read from the catalogue drawing are: B = 35.7, C = 18, D = 62, c = 19.5, m = M 8 x 1, s = 9.0, c0 = 11.3, d1 = 37.4, d2 = 44.0. Sealing is provided by a stamped steel washer with a rubberized lip. The eccentric locking collar allows the inner ring to be clamped directly onto the shaft, giving a fixed axial and radial position once tightened, without requiring a separate fitting tolerance procedure on the shaft. The stamped steel washer with rubberized lip restricts the ingress of dust and coarse contaminants into the raceway area while retaining grease inside the bearing. Symbol SA 206 AV12 corresponds dimensionally and constructionally to SKF YET 206.
