Scope
JB/T 15540-2026 is the English-translated version of 关节轴承航空自润滑向心关节轴承.
JB/T 15540-2026 is part of the spherical plain bearings series and concerns self-lubricating radial spherical plain bearings for aerospace use. These are joint bearings that allow angular movement and carry radial load, with a self-lubricating design that works without added grease. The standard treats them as an aerospace product.
Aerospace bearing manufacturers, aircraft and equipment makers, buyers and test laboratories can use it. It is a voluntary standard, as the /T in the code indicates. It was approved by the Ministry of Industry and Information Technology, issued on 13 February 2026 and takes effect on 1 September 2026. It is a new standard.
