Matching seal (radial shaft seal)
140 × 250 × 15 mm
Seal weight: ≈ 0.54 kg
Other common widths: 140 × 250 × 12 mm, 140 × 250 × 20 mm
The seal's inner diameter matches the shaft (140 mm) and its outer diameter matches the housing bore (250 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 3128 · shaft 125 mm
Adapter sleeve H 3128: shaft diameter 125 mm, bearing bore 140 mm, width 97 mm. Used with lock nut KM28 and lock washer MB28.
H 3128 set weight (incl. lock nut and lock washer): ≈ 4.2 kg
Withdrawal sleeve AHX 3128: shaft diameter 135 mm, width 83 mm.
AHX 3128 weight: ≈ 1 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: 22228 K.
