Matching seal (radial shaft seal)
100 × 215 × 15 mm
Seal weight: ≈ 0.42 kg
Other common widths: 100 × 215 × 12 mm, 100 × 215 × 20 mm
The seal's inner diameter matches the shaft (100 mm) and its outer diameter matches the housing bore (215 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 320 · shaft 90 mm
Adapter sleeve H 320: shaft diameter 90 mm, bearing bore 100 mm, width 71 mm. Used with lock nut KM20 and lock washer MB20.
H 320 set weight (incl. lock nut and lock washer): ≈ 1.6 kg
Withdrawal sleeve AHX 320: shaft diameter 95 mm, width 59 mm.
AHX 320 weight: ≈ 0.46 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: 21320 K.
