Designation meaning and notes

  • Standard length.
  • UU: Seals at both ends

Dimensions are standard catalogue values; the weight is an approximate calculation. Please confirm before ordering.

Matching seal (radial shaft seal)

80 × 120 × 10 mm

Seal weight: ≈ 0.078 kg

Other common widths: 80 × 120 × 8 mm, 80 × 120 × 12 mm

UU-type linear bearings have their own seals at both ends.

The seal's inner diameter matches the shaft (80 mm) and its outer diameter matches the housing bore (120 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.
