Matching seal (radial shaft seal)
90 × 190 × 12 mm
Seal weight: ≈ 0.29 kg
Other common widths: 90 × 190 × 10 mm, 90 × 190 × 15 mm
The seal's inner diameter matches the shaft (90 mm) and its outer diameter matches the housing bore (190 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 2318 · shaft 80 mm
Adapter sleeve H 2318: shaft diameter 80 mm, bearing bore 90 mm, width 86 mm. Used with lock nut KM18 and lock washer MB18.
H 2318 set weight (incl. lock nut and lock washer): ≈ 1.6 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: 2318 K.
