Mercedes Vito Top Strut Bearing

Mercedes Vito Top Strut Bearing is a core load-bearing component of the front suspension system of Mercedes-Benz Vito series commercial vehicles, specially built for high-load usage scenarios such as urban logistics and business passenger transport. Installed at the connection between the top of the front shock absorber and the vehicle body, it undertakes the three key functions of bearing vehicle load, transmitting steering torque and isolating road vibration. As an original manufacturer with 20 years of deep engagement in commercial vehicle bearings, our Mercedes Vito Top Strut Bearing is manufactured in strict accordance with Mercedes-Benz commercial vehicles' global unified technical standards. It is specially reinforced for the chassis characteristics of all Vito models such as W447 and W639, and perfectly fits the original mounting positions. It can be directly replaced without any modification, which can effectively solve the problems of bearing abnormal noise, looseness and heavy steering caused by long-term heavy-load driving of commercial vehicles, and greatly reduce vehicle operation and maintenance costs.

Our Mercedes Vito Top Strut Bearing adopts a heavy-duty structural design exclusive for commercial vehicles: the raceway adopts a widened and thickened design, with 60% higher load capacity than ordinary passenger vehicle bearings, which can easily cope with long-term driving of Vito models under a fully loaded 3.2 tons state; the sealing system is upgraded to a four-layer protective structure, including rubber main seal, dust retaining ring, metal dust cover and waterproof ring, which can maintain excellent sealing performance even in harsh environments such as construction sites, mines and coastal high-salt spray; the interior is filled with Fuchs heavy-duty long-lasting grease from Germany, which has excellent shear resistance and high-temperature stability. One-time filling can meet the use demand of 120,000 kilometers without mid-term maintenance. The raceway material is made of Baosteel GCr15 high-carbon chromium bearing steel. After integral quenching and low-temperature tempering treatment, the hardness reaches HRC 58-62, with extremely high wear resistance and fatigue strength. The metal bracket is stamped from 4mm thick high-quality cold-rolled steel plate, and the surface is treated with double anti-rust treatment of electrophoresis + plastic spraying, with corrosion resistance increased by 70%.

This product is mainly used in the front suspension system of Mercedes-Benz Vito and Viano series commercial vehicles, and widely serves urban logistics distribution, business passenger transport, airport transfer, RV modification and other fields. Our Mercedes Vito Top Strut Bearing is not only supplied to major Mercedes-Benz commercial vehicle 4S stores and parts dealers in China, but also exported in large quantities to Europe, the Middle East, Africa, Southeast Asia and other regions. We have established long-term stable cooperative relations with well-known local commercial vehicle parts wholesalers. The product market repair rate is less than 0.4%, which has been highly recognized by global customers.

We have established a full-industry-chain quality control system for commercial vehicle bearings, which is fully managed by an independent quality department to ensure that every Mercedes Vito Top Strut Bearing meets Mercedes-Benz commercial vehicle quality standards. Starting from raw material incoming, we have set up 18 quality inspection checkpoints. All raw materials come from suppliers that have passed strict audits. Each batch of GCr15 bearing steel must pass chemical composition analysis and metallographic inspection by direct-reading spectrometer. Unqualified raw materials are never put into production.

In the production process, we implement a three-level inspection system of "first article inspection, process patrol inspection and finished product full inspection", and each process has clear quality standards and operation specifications. Key processes such as quenching, grinding and assembly realize fully automatic production, reducing the impact of human factors on product quality. Before finished products leave the factory, we conduct 100% full inspection. Through self-developed automatic on-line testing equipment, we test key indicators such as product torque, rotation smoothness and dimensional accuracy one by one. At the same time, we conduct sampling tests of 800,000-cycle rotational life test (under 18000N axial pressure), high and low temperature cycle test and mud seal test. We accept inspection by any third-party inspection agency designated by customers to fully protect customers' procurement rights and interests.

We have established a fast-response commercial vehicle customer service system to provide professional and efficient after-sales service support for global customers. Pre-sales, our professional technical team will provide customers with detailed product technical materials, adaptation tables and free samples to assist customers in confirming vehicle model compatibility; for large customers, we can provide on-site technical training and installation guidance services. In-sales, we will arrange exclusive order followers to follow up the order progress, and send production progress pictures and videos to customers every week. Orders within 10,000 pieces are guaranteed to be delivered within 30 days.

After-sales, we provide full follow-up service. After the products are sent out, we will provide the logistics tracking number in time for customers to check. If the goods are damaged during transportation, we will arrange reissue within 24 hours; if there are non-artificial quality problems, we will unconditionally replace the products for customers and bear the corresponding shipping costs. For agents purchasing in batches, we provide unsalable product exchange policy and regional market protection policy to reduce customers' business risks. We promise to provide all Mercedes Vito Top Strut Bearings with a warranty service of 1 year or 30,000 kilometers, so that customers can purchase without worry.

We attach great importance to enterprise qualifications and product certifications, and have passed a number of international authoritative certifications to ensure that products meet the access requirements of major global markets. We have obtained IATF 16949:2016 International Automotive Quality Management System Certification, ISO 14001 Environmental Management System Certification and ISO 45001 Occupational Health and Safety Management System Certification, and are a national-level high-tech enterprise and a "Specialized, Refined, Differential, Innovative" small and medium-sized enterprise in Zhejiang Province.

In terms of product certification, our Mercedes Vito Top Strut Bearing has passed EU CE Certification, U.S. DOT Certification and Saudi SASO Certification, and the products meet the technical standards and regulatory requirements of Europe, North America, the Middle East and other regions. We have more than 20 utility model patents and invention patents related to commercial vehicle bearings, covering bearing structure design, manufacturing technology and testing technology. All certification certificates and patent documents can be provided to customers to help them smoothly expand the global market.
