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.
