Project Description

Overworked Railroad Springs

Application: Slack Adjuster Springs

Problem: Existing spring design was getting worked over in application and breaking in service.

The MWI Solution:

  • Analyzed physical failure points and overall application design
  • Developed a new chrome silicon spring design to allow for more clearance
  • Added an “E” coating and performed an extensive shot peening process


Repairs were done using the new springs, in-service breakages were eliminated, and the customers’ later product designs have incorporated the revised spring characteristics.

Transit applications span commuter rail lines, railroad freight carriers, bus lines and more
