Standard Number: JB/T 15540-2026

Standard Name: Spherical Plain Bearings — Self-lubricating Radial Spherical Plain Bearings for Aerospace

Main Content:

This document specifies the structural forms, coding methods, dimensions, and technical requirements for self-lubricating radial spherical plain bearings for aerospace. It describes corresponding test methods and stipulates requirements for inspection rules, marking, protective packaging, transportation, and storage.

This document applies to the manufacturing of aerospace self-lubricating radial spherical plain bearings with PTFE fabric liners and either metric or inch interface dimensions.

Implementation Date: September 1, 2026

Standard Number: JB/T 8874-2026

Standard Name: Rolling Bearings — Split Type Vertical Bearing Housings -Specifications

Main Content:

This document specifies the technical requirements for split vertical bearing housings, describes corresponding test methods, and provides requirements for inspection rules, marking, anti-rust packaging, and storage.

This document is applicable to the manufacturing of split vertical bearing housings with two-bolt and four-bolt designs, with dimensions conforming to GB/T 7813-2018 (Rolling Bearings — Split Vertical Bearing Housings — Boundary Dimensions).

Replaces Standard: JB/T 8874-2010

Implementation Date: September 1, 2026

Standard Number: JB/T 10858-2026

Standard Name: Spherical Plain Bearings — Test Code for Static Load

Main Content: This

document outlines the test principles for static load tests of spherical plain bearings and specifies test equipment, samples, and test conditions. It details corresponding test procedures, requirements for data processing and evaluation, and test report specifications.

This document applies to static load testing for general-purpose radial spherical plain bearings, angular contact spherical plain bearings, thrust spherical plain bearings, and rod end spherical plain bearings. For spherical plain bearings with special requirements (e.g., special materials, sliding surfaces, or clearances), this document can be used as a reference.

Replaces Standard: JB/T 10858-2008

Implementation Date: September 1, 2026

Standard Number: JB/T 10860-2026

Standard Name: Spherical Plain Bearings — Test Code for Life Test

Main Content:

This document specifies the test principles and classifications of life tests for spherical plain bearings, the required equipment, samples, and test conditions. It details corresponding test procedures, data analysis requirements, and test report specifications.

This document applies to life testing for general-purpose spherical plain bearings. For spherical plain bearings with special requirements (e.g., special materials, sliding surfaces, or clearances), this document can be used as a reference.

Replaces Standard: JB/T 10860-2008

Implementation Date: September 1, 2026
