Matching seal (radial shaft seal)
190 × 260 × 15 mm
Seal weight: ≈ 0.44 kg
Other common widths: 190 × 260 × 12 mm, 190 × 260 × 20 mm
The seal's inner diameter matches the shaft (190 mm) and its outer diameter matches the housing bore (260 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 3938 · shaft 170 mm
Adapter sleeve H 3938: shaft diameter 170 mm, bearing bore 190 mm, width 89 mm. Used with lock nut KML38 and lock washer MBL38.
H 3938 set weight (incl. lock nut and lock washer): ≈ 6.2 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: 23938 K.
