The innovative ball bearing guidance system offers both stampers and die makers the following advantages over the common plain bearing system:

  • Registers the die more accurately providing precision parts, longer die life and less maintenance.
  • Ease of assembly or disassembly of the punch holder and die holder providing higher precision dies and reduced die building time.
  • Longer stamping runs (millions of strokes) providing less maintenance down time.
  • Minimizes replacement of guidance components.

In 1963, Lempco introduced the unique “Lempcoloy” plain bearing lubrication free bushing. It has qualities far above those of steel, bronze, or bronze plated bushings:

  • High tensile strength with glass-hard wear-resistance.
  • Extremely low coefficient of friction.
  • No lubrication required (This product is used widely by the food processing industry).
  • Dielectric (Facilitates EDM machining).
  • Excellent thermal conductivity.
  • Corrosion resistant.

Lempcoloy® self-lubricating bushings, standard and short shoulder, are available in 10 sizes starting with 1/2″ inside diameter thru 3″.

In 1987, continuing with its pioneering and innovative philosophy, Lempco introduced the Rotainer®, a multi-directional action guidance system to rotate as well as move vertically on the post. The Rotainer® possesses increased resistance to normal wear, is unaffected by high speed operation and offers precise die registration.

Lempco has proven experience in selecting metals, developing designs, and understanding the details of customer needs to ensure you receive cost-effective performance run after run. Lempco knows what it takes to keep you competitive today, and will continue to strive to keep you competitive into the next millennium.
