Matching seal (radial shaft seal)
105 × 160 × 12 mm
Seal weight: ≈ 0.16 kg
Other common widths: 105 × 160 × 10 mm, 105 × 160 × 15 mm
The seal's inner diameter matches the shaft (105 mm) and its outer diameter matches the housing bore (160 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.
