Project Description

Overworked Railroad Springs

Application: Slack Adjuster Springs

Problem: A customer’s existing spring design was getting overworked in application, leading to breaks while 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, eliminating in-service breakages. The customer’s later product designs have incorporated the revised spring characteristics.

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