Matching seal (radial shaft seal)
3 × 7 × 7 mm
Seal weight: ≈ 0.9 g
Other common widths: 3 × 7 × 10 mm
UU-type linear bearings have their own seals at both ends.
The seal's inner diameter matches the shaft (3 mm) and its outer diameter matches the housing bore (7 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.
