CITIC Heavy Industries

In May 2020, CITIC Heavy Industries initiated a public tender for the upper and lower bearing bushes (designed material: SL-XQZ62) used in the slewing bearings of the Ф4.5×13-meter horizontal converter. The project set stringent standards for product performance and reliability. Prior to this, the market for such self-lubricating bearing bushes had long been dominated by manufacturers in southern China, with high industry competition and technical barriers.

Based on precise market demand analysis and multiple rounds of performance benchmarking tests, SHCM identified the FZB053-type self-lubricating product as an alternative solution for the tender. Through in-depth technical discussions with the client and the design institute, SHCM successfully passed the technical review and obtained bidding qualification. Leveraging the core competitive advantages of the FZB053 product in wear resistance, self-lubricating stability, and cost control, SHCM secured the bid.

After deployment, the product demonstrated stable performance under actual operating conditions, with excellent lubrication performance, fully meeting the technical requirements for long-term, efficient equipment operation. It earned dual recognition from both the technical department of CITIC Heavy Industries and the end-users. This collaboration not only broke the long-standing monopoly of southern enterprises in this niche market but also enabled SHCM to earn the deep trust of an industry-leading client through high-quality products and professional services, officially establishing a long-term partnership for supporting supply.
