Matching seal (radial shaft seal)

45 × 100 × 10 mm

Seal weight: ≈ 0.068 kg

Other common widths: 45 × 100 × 8 mm, 45 × 100 × 12 mm

The seal's inner diameter matches the shaft (45 mm) and its outer diameter matches the housing bore (100 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 2309 · shaft 40 mm

H 2309 set weight (incl. lock nut and lock washer): ≈ 0.27 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: 2309 K.
