Custom CNC Turned 304 Stainless Steel Precision Cylindrical Spacer with Plain

Product Description

This CNC turned stainless steel cylindrical spacer is a precision machined component produced by our professional CNC lathe workshop. The part is fabricated from 304 stainless steel, delivering excellent rust resistance and wear performance.

We adopt numerical turning process for outer diameter and end face, drill plain through hole at center, no thread or tapping on inner bore. The outer circle is high-gloss mirror finish after fine turning, followed by passivation surface treatment to further enhance corrosion resistance.

As a professional custom machined parts manufacturer, we provide custom service & OEM solutions. We can produce custom stainless steel spacer and CNC turned stainless steel cylinder according to your drawings or samples. Strict dimensional tolerance control ensures consistent performance for your assembly projects.

Applications

This precision stainless steel spacer is widely used in mechanical assembly, electronic equipment, instrumentation, automation machinery, medical devices, optical equipment, household appliances and communication hardware. It works as spacing, positioning and supporting component to maintain fixed distance between assembled parts.

Custom & OEM Service

We are a professional manufacturer providing custom service and OEM service for CNC turned metal components. We support custom stainless steel spacer and CNC turned stainless steel cylinder production.

You can send us your 2D/3D drawings or physical samples. We can customize material selection, dimensions, tolerance, surface treatment, hole type and quantity according to your requirements. Small batch and mass production orders are both acceptable.

Key Advantages

• High precision machining, tight tolerance control to solve inaccurate positioning issue during assembly.
• 304 stainless steel material with good anti-rust and wear resistance, avoid spacer damage in humid environment.
• Mirror outer surface plus passivation, no burrs, reduce friction and prevent surface oxidation.
• Custom & OEM service available, produce non-standard size stainless steel spacer to match your unique assembly requirement.
• One-stop CNC turning processing, plain through hole without tapping, meets your special bore structure demand.

Quality Control

We implement full quality control during whole production process. Raw material inspection is carried out before machining. Dimensional inspection with micrometer and optical detector after CNC turning. Surface check for burr, scratch and finish. Final full sampling inspection before packing to guarantee every precision stainless steel spacer meets drawing specification. Material test certificate can be supplied upon request.
