Product Description
Cold Forged Sleeve Bushings are wear-resistant support components in high-load rotating pairs. They are formed by cold forging process, with dense structure and uniform hardness. Compared with traditional machined bushings, they have higher wear resistance and impact resistance, and can work stably for a long time under heavy load conditions. Our Cold Forged Sleeve Bushings are made of high-quality low-carbon steel or alloy steel as raw material, and are integrally formed by cold extrusion. The metal fibers are continuously distributed along the circumferential direction, without the grain breakage defect of cutting processing, and the bearing capacity is increased by more than 30%. The inner hole is subjected to subsequent finishing processing, with high dimensional accuracy and good surface smoothness, which can form a good fit with the rotating shaft and run smoothly without jamming. With 18 years of experience in cold forged parts production, our products have been supplied in bulk to overseas customers in construction machinery, automotive and other industries, with continuous quality recognition.

We can provide Cold Forged Sleeve Bushings with various structures such as straight cylinder type, step type and oil groove type, covering common specifications with inner diameter from 6mm to 60mm, supporting full-size non-standard customization. We can adjust the inner diameter, outer diameter, length and tolerance grade according to customers' shaft diameter size, load working condition and installation space. The product can be subsequently subjected to heat treatments such as carburizing and high-frequency quenching to further improve surface hardness and wear life, and can also be subjected to anti-corrosion treatments such as galvanizing and blackening to adapt to different use environments. Each bushing undergoes strict dimensional inspection, hardness test and roughness test before leaving the factory to ensure that inner hole accuracy, coaxiality and surface quality all meet the standards. For overseas heavy machinery customers, we can also customize bushing products with high load grades to meet the use requirements of extreme working conditions.

Quality Control
We implement strict quality inspection standards for all cold forged sleeve bushings, from material spectral inspection when raw materials enter the factory, to forming size control during cold forging, and then to hardness test after heat treatment, and finally to 100% dimensional full inspection of finished products, checking layer by layer. The core inspection items include inner hole dimensional accuracy, coaxiality, surface hardness, roughness and appearance defects, ensuring that each product meets heavy load use standards. We accept performance testing and inspection from third-party professional institutions. All products come with a 1-3 year warranty period. If there are quality problems such as early wear and deformation, we will reissue and replace them for customers free of charge, fully guaranteeing customers' procurement rights and interests.
After-sales Service
We have established a complete full-process customer service system. Before sales, we can provide free product samples, material inspection reports and selection suggestions, and customers only need to bear the international express freight; during the production stage, we can regularly feedback production progress to customers and provide real-time picture and video updates; after sales, the products come with a 1-3 year warranty period. If quality problems caused by non-human damage occur under normal installation and use conditions, we will provide replacement services for customers at the first time. We promise to respond to all after-sales inquiries within 24 hours to efficiently and quickly solve various customer problems.
Payment Terms
We support flexible and transparent payment methods. For standard specification bushing orders, 30% prepayment is adopted, and the balance is settled against the copy of the bill of lading; for custom heat treatment orders, 40% prepayment is adopted, and 60% balance is settled against the copy of the bill of lading. We accept telegraphic transfer payment in mainstream currencies such as US dollars and euros. For large-volume long-term orders, corresponding tiered price discounts can be provided according to the purchase volume. All payment details are clear and transparent without any hidden fees, fully guaranteeing customers' capital safety and procurement rights and interests.
