Matching seal (radial shaft seal)

25 × 62 × 7 mm

Seal weight: ≈ 0.023 kg

Other common widths: 25 × 62 × 8 mm, 25 × 62 × 10 mm

The seal's inner diameter matches the shaft (25 mm) and its outer diameter matches the housing bore (62 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.
