Matching seal (radial shaft seal)

50 × 110 × 10 mm

Seal weight: ≈ 0.083 kg

Other common widths: 50 × 110 × 8 mm, 50 × 110 × 12 mm

The seal's inner diameter matches the shaft (50 mm) and its outer diameter matches the housing bore (110 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.
