Product Description
Sintered Carbon Steel Bushings are wear-resistant bushing products produced by powder metallurgy sintering process. They are designed for high-load and low-speed rotating pair scenarios, with excellent wear resistance and self-lubricating properties, which can effectively reduce the friction loss between the shaft and the hole and extend the overall service life of the equipment. Our Sintered Carbon Steel Bushings are made of high-quality carbon steel powder as raw material, and are precision processed through multiple processes such as high-temperature sintering, shaping and finishing. They have high dimensional accuracy and good interchangeability, can directly replace similar imported products, and greatly reduce customers' procurement costs. With 18 years of experience in metal parts production, this sintered bushing has been supplied in bulk to customers in the automotive, machinery, home appliance and other industries, and has won wide market recognition.

We can provide sintered carbon steel bushings with various inner diameter, outer diameter and length specifications, supporting full-size non-standard customization to adapt to different installation sizes and load requirements. The product can be oil-impregnated according to specific use scenarios to further improve self-lubricating performance and reduce maintenance costs during equipment operation. Each Sintered Carbon Steel Bushing undergoes strict dimensional inspection and hardness test before leaving the factory to ensure that the inner hole accuracy, roundness and hardness meet industry standards, and the operation is stable without jamming. For bulk orders from overseas purchasers, we support customized packaging and exclusive logo printing to meet customers' branding operation needs.

After-sales Service
We have established a complete full-process customer service system. Before sales, we can provide product samples free of charge, 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, and if there are quality problems caused by non-human damage, 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.
Factory Capabilities
We have 2 production bases in Hangzhou and 1 cold heading factory in Ningbo, equipped with a full set of production equipment such as powder metallurgy sintering furnaces, CNC precision machine tools, shaping machines and heat treatment equipment, with 80 skilled production personnel and a monthly production capacity of 60 tons of various metal parts. We have focused on the R&D and production of non-standard metal parts for 18 years. As the foreign trade export platform under Boming Hardware, our export sales have maintained a steady growth of 38% for consecutive years, and our products are exported to dozens of countries and regions around the world such as Europe, the United States and Australia.
Packaging & Shipping
Our products adopt standard export anti-rust packaging. The inner layer is wrapped with anti-rust paper or sealed plastic bags to prevent rust and bump damage during transportation. The outer layer is reinforced with high-strength hard cartons and wooden pallets as a whole, fully adapting to ocean transportation and multiple transshipment loading and unloading. We support FOB Shanghai port trade terms, and can assist customers in connecting with high-quality freight forwarders. The delivery cycle for both standard orders and custom orders is 30-45 days. For large-volume orders, 24-hour shift production can be arranged to ensure on-time delivery.
