Custom CNC Turn-Mill Aluminum Triangular Flange Bearing Support Post

Custom CNC Turn-Mill Aluminum Triangular Flange Bearing Support Post

Quick detail

This triangular flange bearing support post is manufactured by CNC turn-mill composite machining from solid aluminum billet. Integrated cylindrical bore, triangular mounting flange and top threaded hole are completed in one setup. Black hard anodized surface delivers excellent wear resistance, widely used as shaft support and mounting post in automation equipment.

Product description

This custom aluminum support post is one-piece CNC turn-mill machined from solid aluminum block. The triangular flange base with three mounting holes, central cylindrical bore and top threaded hole are all processed in a single clamping operation, ensuring high concentricity between the bore and flange mounting face.

Chenrong Precision owns dedicated turn-mill composite machines for this type of rotating body parts with flange features. We control the coaxiality of inner bore and outer cylinder tightly, which is critical for shaft support performance. Black hard anodizing treatment provides a hard, corrosion-resistant surface that prevents wear during repeated assembly and disassembly. We can customize flange shape, bore size, post length and top thread specification according to your mechanical drawings.

Product Features

• One-piece turn-mill machining, high concentricity of bore and flange
• Triangular flange base with three mounting holes for stable installation
• Central cylindrical bore for bearing or shaft insertion
• Top threaded hole for end retention and shaft locking
• Black hard anodized surface, wear resistant and anti-corrosion

Product Advantage

We specialize in turn-mill composite machining of flange-type shaft support parts. Single setup machining eliminates cumulative tolerance from multiple operations. Every batch is inspected for bore diameter, flange flatness and hole position before shipment. We support both prototype and volume production with consistent quality.

Application

• ✅ Automation equipment shaft support post
• ✅ Bearing housing bracket for linear motion systems
• ✅ Robotic arm auxiliary support column
• ✅ Optical equipment mounting standoff

FAQ

Q1: Can you customize the triangular flange shape to a square or round flange?

A1: Yes, flange shape (triangular, square, round), hole count and hole positions can all be customized based on your drawings.

Q2: What is the maximum post length you can machine?

A2: We support support posts up to 300mm in length with appropriate flange size. Longer parts can be discussed.

Q3: Can you press-fit a bearing into the central bore before shipping?

A3: We can provide press-fit assembly service for bearings or bushings upon request.

Q4: Is black hard anodizing the only surface option?

A4: Clear anodizing and natural machined finish are also available. Black hard anodizing is recommended for wear resistance.

Q5: What is the typical lead time for this type of part?

A5: 8–12 working days for prototype samples. Mass production lead time depends on order quantity.
