FIELD INITIATED ENGINEERING REVIEW AND PRODUCT REDESIGN YIELDS $170,000 IN COST SAVINGS

## Challenge

Field initiated an engineering review of a customer’s application that revealed a high-cost component, which required multiple assembly steps and created potential quality concerns. Field provided engineering resources to redesign a more cost-effective part that lowered component costs, assembly costs, and improved quality.

Initial Design:  
The initial design was a screw-machined component that contained a groove for which a retaining ring was assembled. This design did not create a consistent stop for the bearing to seat against, which resulted in potential quality issues. The initial design of the part also resulted in high component and total assembly cost.

## Solution

The Field Team designed a one piece powdered metal component, with tight tolerances that are machined in a secondary operation. The newly designed part eliminated the groove, the retaining ring, and the assembly process. This provided a consistently tight tolerance bearing stop that improved quality and reduced components.

## Results

The Field proposed solution resulted in a reduction of assembly time, eliminated quality issues, increased tool life and yielded significant cost savings based on 600,000 EAU:

- Increased Tool Life
- Eliminated Quality Issues
- Piece Price Savings: $120,000
- Savings from Eliminating a Retaining Ring: $35,000
- Savings from Eliminating Assembly Labor: $15,000

****Total Savings with Field: $170,000****
