Custom Precision Spacers and CNC Components for Motors & Drives
Precision components help rotating systems maintain alignment, reliability, and performance. SpacerMFG provides made-to-print CNC machining for OEMs and engineering teams working with high-speed motors, gearboxes, and precision actuators.
Since 2013, we have converted technical drawings into production-ready metal components that help assembly lines minimize downtime and field failures.

Engineered solutions
Components built around your application challenges
Motors and drives must withstand vibration, thermal expansion, and mechanical stress. We manufacture application-specific parts that support reliable assembly and operation.
Discuss your component requirementsPrecision Spacers & Sleeves
Maintain exact axial spacing in motor housings to help prevent internal friction.
Stepped & Flanged Spacers
Integrate multiple diameters into one component to simplify assembly and reduce part count.
Precision Bushings
Support rotating shafts with accurate bores and finish for smooth operation.
Standoffs
Secure PCBs and sensors inside drive enclosures with high-strength threading.
Materials and finishing
Select the right combination for your environment
The operating environment of your motor or drive determines the material and finish required. We offer secondary processing so components can arrive ready for installation.
Additional operations
- ✓Grinding for improved dimensional accuracy
- ✓Precision drilling and reaming
- ✓Laser marking for identification and traceability
Aluminum
Lightweight components with anodizing for corrosion resistance.
Stainless Steel
High-durability parts with passivation for medical or clean-room environments.
Steel
High-strength components with black oxide, nickel, or zinc plating.
Brass & Copper
Conductive and non-sparking options for specialized electronics.
Supporting your engineering lifecycle
From initial prototype to repeat production
We work directly with mechanical and design engineers managing projects from prototype through full-scale production.
Prototyping
Initial samples match your final production specifications, helping validate fit and function early in the design cycle.
Repeat Production
Production management supports consistent tolerance and surface finish from the first part through repeat runs.
Drawing Compliance
Our engineering team reviews required tolerances, chamfers, and thread classes before production begins.
