Brief Introduction

This custom CNC turned aluminum step bushing is precision manufactured by CNC lathe processing. Made of high-quality aluminum alloy, it features light weight, high rigidity, smooth surface finish and tight dimensional tolerance. It is widely used as mechanical sleeve and spacer for automation equipment, instruments and machinery. We support OEM & ODM custom service according to your drawings or samples, factory direct supply with reliable quality.

Product Overview

This aluminum step bushing is a rotary precision mechanical component processed by high-precision CNC turning. The stepped structure is formed in one-time clamping, ensuring excellent concentricity and accurate matching during assembly. Aluminum alloy material brings advantages of low density, good machinability and natural corrosion resistance. Various surface treatments are available as requested, such as brushing, anodizing, sandblasting and polishing.

All finished parts will undergo strict dimensional inspection before shipment to eliminate burrs and guarantee stable performance. We accept both prototype and mass production orders for non-standard custom parts.
