Metal Bushing
Products Description
Metal bushings are precision mechanical components designed specifically for industrial-grade mechanical transmission and assembly positioning applications. Their core feature lies in the deep integration of a high-grade stainless steel base material and a single, precision-formed structure, achieving a unified value across four dimensions: wear resistance, precise positioning, load transfer, and environmental tolerance. Unlike traditional carbon steel bushings (prone to corrosion), plastic bushings (low strength), and ordinary copper bushings (high cost and weak corrosion resistance), this product leverages the inherent corrosion resistance of stainless steel, combined with precision machining and surface strengthening technologies, to fundamentally address the three core pain points in mechanical assembly: widening wear gaps, drifting positioning accuracy, and failure in harsh environments. It is suitable for B2B scenarios such as industrial machinery, automotive manufacturing, and new energy equipment where stringent requirements for assembly accuracy, service life, and environmental adaptability are necessary.
Surface Quality Details
Inner Wall Condition
After precision grinding, the surface roughness Ra≤0.2μm, smooth and burr-free, without scratches, with a delicate feel, reducing frictional wear with the shaft.
Outer Wall Condition
After cold rolling and turning, the surface is flat, without oxide scale or dents, and the flange face perpendicularity error is ≤0.005mm, ensuring a perfect fit.
Surface Treatment Effect
After passivation, the bushing is a uniform silver-gray color, without any blooming or exposed substrate; after nitriding, it is a uniform dark gray color with uniform hardness distribution.
Design Advantages
Integrated Design: Various integrated design solutions are available, including those with flanges, grease fittings, and retaining grooves, reducing the number of parts and simplifying assembly.
Composite Structure Design: Composite bearing sleeve with a steel backing and composite plastics (such as PTFE and POM) are available, combining the strength of metal with the self-lubricating properties of plastics to meet special operating conditions such as dry friction or low-speed heavy loads.
Customized Lubrication Structure: The most suitable oil groove, oil hole, and oil reservoir structure are customized according to the customer's lubrication method (grease lubrication, oil lubrication).
Application Advantages
Enhanced System Reliability
Through dynamic adaptive technology, the failure rate of mechanical systems is reduced by 60%, fundamentally reducing equipment downtime caused by shaft sleeve failure and improving overall system availability.
Extended Equipment Lifespan
Reducing excessive wear caused by dynamic operating conditions extends equipment lifespan by more than 25%, lowering total lifespan maintenance costs.
Optimized Operating Efficiency
Intelligent adjustment ensures the mechanical system is always in optimal operating condition, improving equipment operating efficiency by 10-15% and creating considerable operational value for enterprises.
Adaptability to Cutting-Edge Industrial Scenarios
In emerging fields such as industrial robot joints, precision machine tools, and high-speed rotating equipment, our pump shaft sleeves meet the stringent requirements of high dynamics, high precision, and long lifespan, becoming the preferred support solution for these innovative applications.
