Precision Spacers & CNC Machined Components
Since 2013, SpacerMFG has supported engineering teams and OEMs by transforming technical drawings into high-precision mechanical components. Based in Shenzhen, we manufacture spacers, bushings, sleeves, and standoffs for demanding automation and robotics applications.
Since 2013
Supporting engineering teams
CNC
Turning and milling production
To print
Built to your specifications
Drawing-based production
Dimensions, materials, and finishes matched to your engineering requirements.
Ready-to-assemble parts
Secondary processing coordinated in one manufacturing flow.
Production capabilities
High-precision manufacturing for complex assemblies
Our facility is equipped for CNC turning and milling, allowing us to handle complex geometries and varying batch sizes. In-house control over secondary operations helps reduce lead times and maintain quality from raw material to finished product.
Built around your engineering documentation
We manufacture parts strictly to your print, helping your components integrate into the intended system without design compromises.

Component portfolio
Custom spacer solutions for automation and robotics
The weight, fit, and durability of mounting components can directly affect machine performance. We provide custom-machined parts that support precise alignment and structural integrity.
Precision spacers
Custom outside diameter, inside diameter, and length to eliminate play in assemblies.
Spacer sleeves
Tailored wall thicknesses for load-bearing applications and controlled mechanical spacing.
Stepped & flanged spacers
Multi-diameter profiles that simplify complex mounting and positioning setups.
Threaded spacers & standoffs
Internal or external threading for secure fastening in electronic enclosures and machine frames.
Precision bushings
Hardened or specialized materials selected to reduce wear in moving joints and support consistent operation over time.
Why SpacerMFG
Parts that fit your schedule as well as your specifications
A missing component can stall an entire production line or development project. Our workflow is designed to help engineering teams maintain project momentum from prototype iteration through repeat OEM production.
Discuss your component requirements-
01
Manufacturing to your drawing
We follow your tolerances, material callouts, and finish requirements to eliminate guesswork.
-
02
Flexible production volumes
Our workflow supports small prototype batches and consistent repeat production for OEM supply chains.
-
03
Secondary processing in one flow
Drilling, tapping, anodizing, passivation, and plating are coordinated so you receive finished, ready-to-assemble parts.
-
04
Reliable lead times
Streamlined setup processes help your components arrive when your assembly schedule demands them.
Finishing & post-processing
Surface treatments selected for service life
The longevity of automation equipment often depends on the surface condition of its components. We provide finishing processes that enhance corrosion resistance, appearance, and identification.
Anodizing
For lightweight aluminum components used in automation systems.
Passivation
For stainless steel parts used in medical or clean-room environments.
Nickel, zinc & black oxide
For improved corrosion resistance on steel hardware.
Laser marking
For part numbers and specification identification across inventory and assembly processes.
