Matching seal (radial shaft seal)
80 × 170 × 12 mm
Seal weight: ≈ 0.23 kg
Other common widths: 80 × 170 × 10 mm, 80 × 170 × 15 mm
The seal's inner diameter matches the shaft (80 mm) and its outer diameter matches the housing bore (170 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 316 · shaft 70 mm
Adapter sleeve H 316: shaft diameter 70 mm, bearing bore 80 mm, width 59 mm. Used with lock nut KM16 and lock washer MB16.
H 316 set weight (incl. lock nut and lock washer): ≈ 1 kg
Withdrawal sleeve AH 316: shaft diameter 75 mm, width 48 mm.
AH 316 weight: ≈ 0.28 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: 21316 K.
