Matching seal (radial shaft seal)

120 × 155 × 12 mm

Seal weight: ≈ 0.12 kg

Other common widths: 120 × 155 × 10 mm, 120 × 155 × 15 mm

For thrust bearings, the seal is chosen to suit the shaft diameter and the housing bore.

The seal's inner diameter matches the shaft (120 mm) and its outer diameter matches the housing bore (155 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.
