Repair and custom parts

How Lenex can help

Lenex supports repair work, one-off components, replacement parts, prototypes, and short runs across a wide range of materials, grades, and hardness requirements. Customers can begin with a drawing or model, a worn or broken sample, a sketch, or simply the equipment problem the part needs to solve.

  • Shafts, pins, bushings, and sleeves
  • Shaft and bearing-journal repair
  • Line boring and bore restoration
  • Spray welding to rebuild worn journals, bearing areas, and seal surfaces
  • Finish grinding and machining to restore final size and surface condition
  • Vendor-coordinated heat treatment and protective coatings
  • Material and hardness matched to the application
  • Replacement and custom parts

Repair can often restore a serviceable component instead of forcing the customer to source a complete replacement. Lenex can coordinate machining, spray welding, grinding, heat treatment, coatings, and related vendor work around the dimensions, hardness, toughness, and wear resistance the application requires.

Before you start

Good questions.
Clear next steps.

Repair options, scope, materials, timing, and service arrangements are confirmed for the actual job.

Can I begin with a broken or worn part?

Yes. A sample and a description of its application can help define the work. Final dimensions and requirements need to be established before machining.

Do you coordinate specialty restoration processes?

Lenex can coordinate spray welding, grinding, heat treatment, coatings, and related vendor work around the application’s requirements.
