TS 7411

TS 7411 is a terminology standard for spherical plain bearings. It brings together the terms and definitions used for bearing structure, motion characteristics, angular behaviour, and rod ends, creating a common technical language for design, cataloguing, maintenance, and engineering communication.

Technical scope in context

Spherical plain bearings are joint-like elements that support load while allowing pivoting and oscillatory movement. Their spherical geometry helps accommodate misalignment and angular displacement, so their operating principle differs from rolling bearings and is instead based on sliding contact. As a vocabulary standard, TS 7411 clarifies the meaning of the terms used in this product family, reducing ambiguity in drawings, product data, and technical documentation.

Topics covered by this document

• Spherical plain bearings
• Bearing parts and design features
• Terms related to motion and angles
• Expressions associated with rod ends

The standard is derived from ISO 6811:1983 as an equivalent adoption, so it aligns Turkish technical terminology with established international usage. In practice, standards of this kind are especially useful when discussing the relationship between component form, angular movement, and joint function, because they help ensure consistent naming across engineering and procurement documents.
