Matching seal (radial shaft seal)
150 × 320 × 20 mm
Other common widths: 150 × 320 × 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 (150 mm) and its outer diameter matches the housing bore (320 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.
