Matching seal (radial shaft seal)
55 × 120 × 10 mm
Seal weight: ≈ 0.099 kg
Other common widths: 55 × 120 × 8 mm, 55 × 120 × 12 mm
The seal's inner diameter matches the shaft (55 mm) and its outer diameter matches the housing bore (120 mm); the width depends on the space in the housing. NBR (double lip, TC type) is recommended for general use and FKM (Viton) for high temperatures.

Matching sleeve
H 2311 · shaft 50 mm
Adapter sleeve H 2311: shaft diameter 50 mm, bearing bore 55 mm, width 59 mm. Used with lock nut KM11 and lock washer MB11.
H 2311 set weight (incl. lock nut and lock washer): ≈ 0.41 kg
Withdrawal sleeve AHX 2311: shaft diameter 50 mm, width 54 mm.
AHX 2311 weight: ≈ 0.22 kg
A sleeve mounts a tapered-bore bearing on a plain cylindrical shaft and bridges the difference between the bearing bore and the shaft diameter.
Use with a sleeve requires the tapered-bore version of the bearing: 22311 K.
