Detailed description

Custom CNC Turned Stainless Steel Flanged Shoulder Bushing

Our custom CNC turned stainless steel flanged shoulder bushings are precision stepped annular spacer components with raised flange limit structure and counterbore inner hole. As a professional Dongguan-based CNC machining manufacturer, we produce non-standard locating sleeves with ±0.01mm high precision fully according to customers’ engineering drawings. The flanged shoulder design realizes accurate spacing and axial limiting during assembly, widely used for interval positioning, shaft isolation and fastening matching on automation fixtures, testing equipment and precision mechanical assemblies. We offer full OEM & ODM customization to meet diversified assembly requirements for global industrial equipment buyers.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi-axis turning centers, solid metal bars are shaped through continuous cutting, facing, grooving, threading and boring operations with computer-controlled accuracy.
Compared with manual machining and traditional milling, precision CNC turning delivers consistent dimensional tolerances down to ±0.01mm, smooth surface finishes and excellent repeatability across high-volume production runs. It is widely used to produce pins, shafts, bushings, connectors and threaded components for mold tooling, electronic devices, medical equipment, automotive systems and industrial automation machinery.
With advanced multi-axis turning capabilities and secondary milling support, CNC lathe technology supports custom geometries including stepped diameters, ball heads, hex bodies and precision slots, which perfectly meets the diversified demands of precision locating components for industrial equipment.

What Is Flanged Shoulder Bushing & Its Industrial Role

A flanged shoulder bushing is a stepped circular locating spacer featuring an outer limiting flange and counterbore inner bore. The protruding flange acts as a stop surface to control assembly depth, while the inner through hole is matched with shafts or bolts for sleeving installation.
In automated production lines, precision test jigs and mechanical fastening structures, this bushing serves as the key spacing and limiting part. Strict concentricity, inner and outer diameter tolerance are necessary to avoid assembly shaking, spacing deviation and component wear under long-term operation. Poor dimensional precision will cause unstable equipment operation and shortened service life, so high-precision CNC custom flanged shoulder bushings are essential matching hardware for industrial precision assembly.

Custom CNC Turned Stainless Steel Flanged Shoulder Bushing

We provide one-stop custom CNC turning services for flanged shoulder bushings and various stepped spacer sleeves, serving automation equipment manufacturers, precision jig factories and electronic machinery enterprises worldwide.
Our product range covers all kinds of customized annular spacing hardware: counterbore flanged locating sleeves, stepped shoulder spacer bushings, zinc-plated limit sleeves, thin-thickness flange gaskets and non-standard large-diameter custom spacer sleeves.
All items are processed via precision CNC lathe turning, including counterbore boring, shoulder forming, chamfering and deburring procedures. We complete all machining and surface treatment strictly in accordance with your 2D/3D drawings. Besides individual single bushings, we also provide parts matching service, convenient for you to purchase supporting shaft and fastener accessories together.

Key Advantages of Our CNC Turned Flanged Shoulder Bushings

Stable dimensional precision & high concentricity

All bushings are processed on multi-axis CNC turning equipment with full-process size monitoring. Unified inner hole, outer circle and flange size ensure consistent limiting & spacing effect for each piece, effectively preventing assembly offset and mechanical jitter.

Flexible secondary processing & accessory matching service

On the basis of standard turning forming, we support personalized adjustment of inner aperture, overall thickness, flange height and counterbore depth. We can also be matched with threaded shafts, pins and gaskets as your needs, reducing your secondary processing workload and shortening equipment production cycle.

Wear-resistant & anti-corrosion for continuous industrial operation

We adopt stainless steel, carbon steel and aluminum alloy as raw materials. Optional zinc plating, nickel plating, passivation and other surface treatments greatly improve rust resistance and wear resistance, adapting to long-time working conditions of various workshop environments.

Fully customizable overall structural design

We can freely adjust inner hole size, outer diameter, total thickness, flange thickness and inner counterbore parameters based on your assembly demands. Brand new irregular structural designs are acceptable for your new-generation equipment upgrading.

Reliable mass production & on-time delivery

From small batch prototype trial production to large-volume bulk orders, we always adopt unified strict quality inspection standards. Abundant production capacity guarantees continuous stable supply, supporting long-term procurement plans of global industrial customers.

OEM Custom Service Scope

We provide comprehensive tailor-made solutions for custom flanged shoulder bushings and all types of precision CNC turned components. For material selection, we work with SUS304 and SUS316 stainless steel, 1018 and 1045 carbon steel, 6061 and 7075 aluminum alloy, as well as C36000 brass, all available in a wide range of bar diameters to match your design specifications.
On component customization, our manufacturing scope covers knurled locating pins, dowel pins, shoulder pins, alignment pins, stepped shafts, and virtually any custom precision turned parts based on your unique requirements. For surface finishing, customers can choose from passivation, electropolishing, zinc and nickel plating, black oxide, anodizing, sandblasting and mechanical polishing to meet specific corrosion resistance and appearance needs.
In terms of service mode, we supply both individual precision turned parts and kitted pre-assembled locating components according to your production workflow. For custom tooling and fixtures, we develop exclusive turning tooling based on your engineering drawings or physical samples, with full support for small-batch prototype testing before mass production.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
