Matching seal (radial shaft seal)
40 × 60 × 7 mm
Seal weight: ≈ 0.017 kg
Other common widths: 40 × 60 × 10 mm
UU-type linear bearings have their own seals at both ends.
The seal's inner diameter matches the shaft (40 mm) and its outer diameter matches the housing bore (60 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.
