2025-11-28 Latest Update:
Recently, the international standard proposal ISO/NP 25994: Spherical plain bearings – self-lubricating bearings of PTFE fabric liner type, led by Fujian Longxi Bearing (Group) Co., Ltd., has been officially approved and entered the formal drafting stage after the New Work Item Proposal (NP) voting process by ISO/TC4/SC7. This marks China's first successfully initiated international standard for self-lubricating bearings and is also the world's first product standard specifically targeting self-lubricating bearings of the PTFE fabric liner type. It signifies a historic breakthrough for China in the high-end technology field of self-lubricating bearings, transitioning from "technology follower" to "standard setter," and holds milestone significance.
Self-lubricating spherical plain bearings with PTFE fabric liners feature maintenance-free operation, self-lubrication, low friction, high load capacity, high wear resistance, and long service life. They are core foundational components in high-end sectors such as aerospace, advanced equipment, precision instruments, and humanoid robots. This standard systematically defines a series of key technical indicators for PTFE fabric liner-type self-lubricating bearings, including product structure, technical requirements, and testing methods. Previously, the technical standards and specification systems in this field were long dominated by multinational corporations from a few developed countries. The successful initiation of this international standard not only reflects China's globally leading technical expertise and mature industrial application experience in this area but also means that the design, manufacturing, and acceptance of such products worldwide will henceforth follow a standard led by China. This significantly enhances China's international discourse power and industrial competitiveness in the field of high-performance bearings.
Longxi Bearing Group led the entire process of this international standard initiation, from preliminary technical research and draft standard preparation to the submission of the formal proposal, presentation at the initiation meeting, and technical defense, laying a solid foundation for the successful approval of the standard. Moving forward, the group will complete the compilation tasks according to the planned requirements to ensure the smooth release of the standard.
