The Benefits of 420 Chrome Stainless Steel Coiled Spring Pins

In applications requiring a combination of high strength, superior fatigue life, and corrosion resistance, 420 martensitic chrome stainless steel offers a host of technical benefits and provides an overall robust cost-effective solution.

Muffler Hanger

A world class rubber molding house manufactures a rubber damper used as a muffler hanger. The hanger attaches the muffler to the under carriage of the vehicle. Spacers or Bushings are required to prevent damage to the rubber hanger.

This customer was using a piece of cut tubing that required a secondary operation to deburr the tubing. This additional step makes cut tubing more costly than a SPIROL split seam, butted Spacer. SPIROL's standard Spacer does not require a secondary deburring operation to ensure clean, burr free ends due to our proprietary forming process.

While the customer had no performance issues with the use of cut tubing, they were wanted to reduce the cost of the assembly.

tubular spacers

SPIROL Spacers eliminate the secondary operation.

SPIROL Engineering was able to recommend the use of a standard Spacer in this application. SPIROL's standard Spacer would perform the same as the cut tubing — but at a fraction of the cost. In past experiences, we have seen the price of cut tubing to be 2.5 times the price of SPIROL standard Spacer. Depending on annual usage, changing from cut tubing to a standard Spacer can save a significant amount of money. In this case, the customer saved $15,000 annually.

Additionally, due to the fact that a standard SPIROL Spacer was recommended, samples were supplied free of charge and shipped immediately from stock.

SPIROL's core purpose is to increase the competitiveness of our customers through value-added technical consulting. Our staff of engineers will review your application needs and work with your design team to recommend the best solution.
