New Press Roll – Design & Manufacture

One of the leading global manufacturers of paper products consulted with Western Machine to upgrade and manufacture a new roll that can meet current loading and operating parameters, and machine chemistry. Our team worked closely with the customer to design a new roll with a new plated head design, increased wall thickness, and grease assist for easier bearing removal. The new roll was manufactured completed and delivered machine ready.


  • Component: Press roll
  • Details: 128.635″ overall length, weighs 4 tons
  • Customer: Global manufacturer of paper products


  • Shafts on existing roll cracked due to collision and applied load.
  • The existing roll design did not allow for shaft replacement.
  • OEM drawing was not available.

Engineered Solutions:

  • WMW engineers worked with the customer to determine current roll loading and machine chemistry.
  • Prior roll was dimensionally inspected to create preliminary design drawings.
  • Prior roll design was analyzed via FEA and Endurance limit calculations.
  • Roll shell and shafting were determined to be inadequate for current machine loading and chemistry.
  • Roll design was modified to withstand current loading.
  • Shaft material was selected to meet loading criteria and machine chemistry.
  • New roll was manufactured complete including new roll cover, grinding, and dynamic balancing.
  • Roll was assembled with bearings and housings and delivered to the customer “machine ready.”


  • Upgraded roll design increases roll performance to meet demanding production requirements.
  • Long-term cost savings and asset protection.
