Matching seal (radial shaft seal)
200 × 280 × 15 mm
Seal weight: ≈ 0.54 kg
Other common widths: 200 × 280 × 12 mm, 200 × 280 × 20 mm
The seal's inner diameter matches the shaft (200 mm) and its outer diameter matches the housing bore (280 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 3940 · shaft 180 mm
Adapter sleeve H 3940: shaft diameter 180 mm, bearing bore 200 mm, width 98 mm. Used with lock nut KML40 and lock washer MBL40.
H 3940 set weight (incl. lock nut and lock washer): ≈ 7.2 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: 23940 K.
