Matching seal (radial shaft seal)
45 × 100 × 10 mm
Seal weight: ≈ 0.068 kg
Other common widths: 45 × 100 × 8 mm, 45 × 100 × 12 mm
The seal's inner diameter matches the shaft (45 mm) and its outer diameter matches the housing bore (100 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.
