Matching seal (radial shaft seal)
40 × 90 × 10 mm
Seal weight: ≈ 0.055 kg
Other common widths: 40 × 90 × 8 mm, 40 × 90 × 12 mm
The seal's inner diameter matches the shaft (40 mm) and its outer diameter matches the housing bore (90 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 2308 · shaft 35 mm
Adapter sleeve H 2308: shaft diameter 35 mm, bearing bore 40 mm, width 46 mm. Used with lock nut KM8 and lock washer MB8.
H 2308 set weight (incl. lock nut and lock washer): ≈ 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: 2308 K.
