Made to drawing
Precision spacers shaped around your application
Whether you need standard wheel spacers or custom-stepped profiles, our process is built around your technical documentation. We manufacture to your drawings and material specifications to reduce the risk of misinterpretation.
Custom geometry
Specific OD, ID, and length requirements, including non-standard thicknesses.
Stepped and flanged profiles
Complex profiles can be machined in a single setup to maintain concentricity between diameters.
Internal and external threading
Standard or custom pitch requirements support secure mounting across your assembly.
Designed for dimensional confidence
Strict control of machining parameters and raw material sourcing helps ensure that every component integrates correctly into your assembly.
Applications
Material and finish
Select performance for the job
We match alloys and secondary processing to your requirements for corrosion resistance, wear life, handling, and appearance.
Aluminum
Lightweight options with anodizing for improved wear resistance.
Stainless steel
303, 304, and 316 grades with passivation for harsh environments.
Steel and brass
Cost-effective choices with black oxide, zinc, or nickel plating.
Edge finishing and surface preparation
Precision deburring and polishing support safe handling and proper seating within your assemblies.
Engineering plastics and copper
Additional material options are available when your component requires specific weight, conductivity, or application characteristics.
Production workflow
Support for your engineering timeline
Our workflow is designed to reduce downtime and help your team validate designs before moving into larger production quantities.
-
01
Prototype quickly
CNC turning supports accurate prototypes for cylindrical components and early design validation.
-
02
Scale with consistency
Consistent setup processes help final production batches match the quality of initial samples.
-
03
Identify every component
Laser marking provides clear identification so supply chain teams can manage inventory without confusion.
