Matching seal (radial shaft seal)
140 × 300 × 20 mm
Other common widths: 140 × 300 × 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 (140 mm) and its outer diameter matches the housing bore (300 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.
