Bushings for steel pistons and connecting rods

Large view Bushings for steel pistons and connecting rods

Performance demands on steel pistons and connecting rods are constantly rising. For extreme loads Wieland-U17 is used. For medium loads also Wieland-SB8 can be used. With respect to connecting-rod bushings Wieland offers to do a PC calculation for the design.

Wieland U17 and Wieland-L67

Bushings for engines, in particular for pistons and connecting rods, should always be made of wrought alloys and not of cast alloys.

Wieland-L67 for machined bushings

Best press fit of all materials (press-out force equal to or higher than press-in force)

  • Very good corrosion resistance
  • Both alloys are wrought alloys
  • Coefficient of expansion L66/L67, (20°C – 300°C) 18x10-6xK-1
