| High Light | CNC brass copper sleeve bushings ，high precision automotive bushings ，wear resistant CNC sleeve bushings | ||
Situo Hardware is a professional custom auto precision copper parts factory in China. We specialize in manufacturing Custom CNC Brass Copper Sleeve Bushings for global automotive mechanical systems. Our copper bushings are made of high-purity solid brass and red copper rods, processed by integrated CNC turn-mill precision machining.
Compared with die-cast and sintered copper sleeves, our products feature higher density, smoother inner wall, higher dimensional stability and excellent noise reduction performance. With natural self-lubricating, anti-seize and wear-resistant properties, these precision copper bushings are widely used in automotive chassis, braking, steering, transmission and shock absorption structures.
They effectively solve common problems such as shaft wear, abnormal noise, jamming and friction loss. We support full non-standard customization to meet precision assembly demands for new energy vehicles, fuel vehicles and engineering machinery vehicles.
We adopt high-quality H59, H62 brass and pure red copper raw materials. Each batch undergoes strict material inspection and hardness testing to ensure pure texture without pores or impurities. Copper material features low friction coefficient, excellent self-lubrication, anti-seize and shaft-protection performance. It requires less maintenance during long-term reciprocating operation.
Compared with steel and iron bushings, our copper sleeves deliver better noise reduction, wear resistance and buffering performance, adapting perfectly to complex high-frequency vibration and alternating temperature working conditions of automotive chassis.
All inner holes, outer circles, end faces, oil grooves and positioning steps are completed in one clamping setup. Roundness, coaxiality and verticality are precisely controlled, achieving stable tolerance within ±0.005mm. The inner wall adopts mirror finishing with smooth and burr-free surface.
Uniform assembly clearance ensures smooth operation without jamming or eccentric wear, fully meeting micron-level assembly and silent operation standards of automotive OEM parts.
Processed from solid copper rods, the one-piece structure features high density without loose layers or pores. It effectively withstands long-term high-frequency vibration, reciprocating friction and instantaneous impact load during vehicle operation.
The copper bushings maintain stable structural strength, avoiding wear, deformation and loosening. They greatly improve vehicle handling accuracy and driving comfort by solving chassis shaking, abnormal noise and excessive clearance problems.
We provide comprehensive custom services: micro precision copper bushings, lengthened sleeves, thickened wear-resistant copper sleeves, oil groove copper sleeves, step positioning copper parts and special-shaped copper components.
Custom processing is available according to customer drawings and samples, covering new energy vehicle electronic control systems, fuel vehicle chassis heavy-duty structures and modified vehicle accessories. Fast prototyping and mass production are fully supported.
All copper bushings undergo stress relief treatment, full dimensional inspection, roundness calibration and assembly simulation test before delivery. 100% visual inspection ensures zero burrs and stable batch consistency.
The qualified rate remains above 99%, complying with international automotive parts export standards. We provide long-term stable OEM and ODM supporting services for global auto parts manufacturers.
As a professional CNC copper bushing manufacturer in China, Situo Hardware owns complete independent production lines for precision copper parts. We support 24-48 hours rapid prototyping, 3-7 days batch delivery and large-scale mass production. Material certificates and dimension inspection reports can be provided.
With stable export quality and flexible customization capability, we offer one-stop CNC copper bushing solutions for global automotive mechanical component buyers.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) to better serve our customers' needs.
Our maximum processing outer diameter is 60, and the minimum control tolerance is 0.001. We have Japanese CNC Tsugami, CNC Citizen, multi-station cold extrusion forming machines, 500T press machines, casting equipment, and various process equipment, which can effectively provide customers with the best technical solutions.
Our company has a total of 300 employees, including 20 technicians, 10 engineers, and 15 quality control personnel. We have over 300 pieces of equipment.
Our company implements 8S management and has passed ISO9001 and TS16949 automotive certifications.
Our customers include Foxconn, Motors, Husqvarna, Shimano, NVIDIA, DJI Drones, Siegenia.
