Product description

This stainless steel hollow cylinder sleeve is precision machined on CNC lathe. The outer cylindrical surface, inner bore and external thread are completed in one clamping to guarantee concentricity and dimensional accuracy.

Chenrong Precision specializes in stainless steel turning parts with high surface requirements. Mirror polishing removes surface scratches and improves smoothness. Passivation treatment further enhances anti-rust performance. We can customize outer diameter, inner bore size, thread specification, total length and surface finish to match your engineering drawings.

Product Features

• High concentricity hollow tube structure processed by CNC turning
• Accurate external thread for tight assembly connection
• Mirror polished surface with low surface roughness
• Excellent corrosion and rust resistance
• Smooth inner bore for fluid passage or shaft fitting

Product Advantage

We are experienced in turning long stainless steel tubular components. Our lathe equipment ensures good concentricity for long hollow parts. Every batch will inspect thread size, dimensional tolerance and surface roughness. We support sample trial and stable mass production for overseas industrial clients.

Application

• ✅ Hydraulic & pneumatic pipeline connecting sleeve
• ✅ Pressure equipment cylindrical housing and bushing
• ✅ Mechanical transmission shaft sleeve for motion assembly
• ✅ Food & chemical fluid handling system pipe component

FAQ

      Q1: Can you customize different thread standards?

      A1: Yes, we can produce metric, UNC, UNF and BSP threads according to your requirements.

      Q2: What is the difference between 304 and 316L stainless steel for this sleeve?

      A2: 316L provides better resistance to saltwater and chemical corrosion, while 304 is cost-effective for general indoor and normal wet environments.

      Q3: Can we change the inner bore diameter and wall thickness?

      A3: Absolutely, inner bore, wall thickness and overall length are fully customizable based on your drawings.

      Q4: What roughness can mirror polishing achieve?

      A4: Mirror polishing can reach Ra ≤0.08μm, suitable for high smoothness assembly and fluid flow requirements.

      Q5: What is the lead time for mass order?

      A5: Normally mass production lead time is 10-13 working days after sample confirmation.
