Matching seal (radial shaft seal)
110 × 280 × 15 mm
Seal weight: ≈ 0.83 kg
Other common widths: 110 × 280 × 12 mm, 110 × 280 × 20 mm
The seal's inner diameter matches the shaft (110 mm) and its outer diameter matches the housing bore (280 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.
