Matching seal (radial shaft seal)
180 × 380 × 20 mm
Other common widths: 180 × 380 × 15 mm
Seals this size are often made to order; send us the housing size and we'll confirm together.
The seal's inner diameter matches the shaft (180 mm) and its outer diameter matches the housing bore (380 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.
