Matching seal (radial shaft seal)
50.8 × 92.075 × 10 mm
Seal weight: ≈ 0.053 kg
Other common widths: 50.8 × 92.075 × 8 mm, 50.8 × 92.075 × 12 mm
The seal's inner diameter matches the shaft (50.8 mm) and its outer diameter matches the housing bore (92.075 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.
