Matching seal (radial shaft seal)
100 × 165 × 12 mm
Seal weight: ≈ 0.18 kg
Other common widths: 100 × 165 × 10 mm, 100 × 165 × 15 mm
The seal's inner diameter matches the shaft (100 mm) and its outer diameter matches the housing bore (165 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 3120 · shaft 90 mm
Adapter sleeve H 3120: shaft diameter 90 mm, bearing bore 100 mm, width 76 mm. Used with lock nut KM20 and lock washer MB20.
H 3120 set weight (incl. lock nut and lock washer): ≈ 1.7 kg
Withdrawal sleeve AHX 3120: shaft diameter 95 mm, width 64 mm.
AHX 3120 weight: ≈ 0.51 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: 23120 K.
