Built around your design intent
Why custom alignment spacers matter
Alignment spacers provide the critical spacing required for structural integrity and functional accuracy in mechanical assemblies. Off-the-shelf parts can fail when complex machinery demands specific tolerances, materials, wall thicknesses, stepped profiles, or exact bore diameters.
Our manufacturing process matches each spacer to your design intent, helping eliminate assembly issues caused by standard, non-compliant hardware.
01
Exact bore diameters
02
Specified wall thickness
03
Stepped profiles
Manufacturing capabilities
One coordinated workflow for precision components
From cylindrical turned parts to complex milled profiles and finishing operations, our capabilities support complete print-to-part production.
01
CNC turning
Precision CNC lathes maintain control of outside diameter, inside diameter, and concentricity requirements.
- Part types: Spacers, sleeves, bushings, pins, shafts, collars
- Materials: Aluminum, stainless steel, carbon steel, brass, copper, plastics
- Features: Steps, grooves, chamfers, precise threading
- Tolerances: Machined to your drawing requirements
02
CNC milling
Milling operations add non-cylindrical features without moving components to secondary suppliers.
- •Pockets, slots, counterbores, and complex geometric profiles
- •High-speed machining for brackets, blocks, and mounting components
- •Combined milling and turning for highly customized alignment components
03
Secondary processing and surface finishing
We manage the additional operations required for dimensional accuracy, safe handling, environmental performance, and installation readiness.
- Mechanical: Grinding and deburring
- Surface: Anodizing, passivation, zinc, nickel, and black oxide plating
- Identification: Laser marking for part numbers, batch tracking, and assembly identification
Engineering partnership
Practical support for OEM development and sourcing
We work directly with mechanical engineers, sourcing managers, and product development teams. Our workflow begins with your drawings, material specifications, and tolerance targets.
Review your technical documentation
We assess drawings, material requirements, and tolerance targets at the quoting stage.
Identify manufacturing efficiencies
Our team looks for ways to reduce costs while maintaining the integrity of your design.
