Matching seal (radial shaft seal)

30 × 42 × 7 mm

Seal weight: ≈ 9 g

Other common widths: 30 × 42 × 10 mm

The seal's inner diameter matches the shaft (30 mm) and its outer diameter matches the housing bore (42 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.
