Custom Blue Anodized CNC Precision Machined Aluminum Alloy Sleeve Bushing with

Situo Hardware is a professional CNC precision machining factory specializing in custom aluminum alloy sleeve parts. We focus on manufacturing Custom Blue Anodized Sleeve Bushing and CNC Precision Machined Non-Standard Aluminum Alloy Sleeve Parts for industrial automation, precision instruments, new energy electromechanical equipment and tooling fixtures.

We adopt industrial-grade 6061/6063 solid aluminum alloy with uniform density and low internal stress. Professional stress relief treatment effectively prevents deformation and warping during long-term operation.

• Lightweight aluminum material reduces equipment operating load and energy consumption compared with steel bushings
• Excellent toughness and fatigue resistance
• Adapts to high-frequency reciprocating sliding and rotating working conditions without scratching or jamming

All aluminum sleeve bushings are completed in one clamping process, finishing inner and outer circle processing, end face trimming, step positioning and chamfering at one time.

• Stable machining tolerance reaches ±0.005mm
• Strictly controlled concentricity and roundness ensure uniform fitting clearance
• Burr-free smooth inner wall meets high-precision assembly and high-speed transmission requirements

Custom blue hard anodizing forms a dense and firm protective layer on the aluminum sleeve surface, greatly improving surface hardness, wear resistance and scratch resistance.

• Excellent anti-corrosion and insulation performance
• Adapts to humid, dusty and slightly corrosive industrial environments
• Uniform blue color will never fade or peel off

We provide unlimited non-standard customization of all aluminum sleeve bushings, including straight-through sleeves, stepped positioning bushings, limit isolation sleeves, slotted buffer sleeves, thin-wall precision casings and special-shaped long/short bushings.

• Custom inner diameter, outer diameter, length and structural shapes available
• Rapid prototyping, small-batch trial production and large-scale OEM mass production

All blue anodized aluminum sleeves undergo full dimensional inspection, precision roundness calibration and surface quality testing before delivery.

• Batch qualified rate exceeds 99%
• High consistency and interchangeability with uniform color and flawless appearance
• Fully compliant with international export standards

Situo Hardware has complete independent production capacity for custom non-standard aluminum sleeve parts. We integrate precision CNC machining and professional blue anodizing surface treatment.

We support 24-48 hours fast prototyping, flexible batch orders and global export delivery. We provide one-stop customized solutions including structural optimization, personalized surface treatment and standard export packaging.
