Matching seal (radial shaft seal)
60 × 130 × 12 mm
Seal weight: ≈ 0.13 kg
Other common widths: 60 × 130 × 10 mm, 60 × 130 × 15 mm
The seal's inner diameter matches the shaft (60 mm) and its outer diameter matches the housing bore (130 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 2312 · shaft 55 mm
Adapter sleeve H 2312: shaft diameter 55 mm, bearing bore 60 mm, width 62 mm. Used with lock nut KM12 and lock washer MB12.
H 2312 set weight (incl. lock nut and lock washer): ≈ 0.49 kg
Withdrawal sleeve AHX 2312: shaft diameter 55 mm, width 58 mm.
AHX 2312 weight: ≈ 0.26 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: 22312 K.
