Matching seal (radial shaft seal)
17 × 47 × 7 mm
Seal weight: ≈ 0.014 kg
Other common widths: 17 × 47 × 10 mm
The seal's inner diameter matches the shaft (17 mm) and its outer diameter matches the housing bore (47 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.
