TS EN ISO 8826-2

TS EN ISO 8826-2 is a drafting standard focused on the detailed simplified representation of rolling bearings in technical drawings. In machine design, bearings are often shown with conventional or simplified graphics rather than as fully detailed geometry, so the drawing remains clear, readable, and suitable for communication across design, manufacturing, and assembly workflows.

What this standard addresses in drawing practice

The standard covers detailed simplified representations for various rolling bearing types. In practical drafting terms, that means the bearing can be shown with the information needed to identify its functional form and installation context without burdening the drawing with unnecessary detail. This helps distinguish the bearing’s essential layout from the surrounding mechanical features in an assembly or part drawing.

From a general technical perspective, rolling bearings support rotating motion and reduce friction between moving parts. In engineering drawings, their correct representation matters because bearings interact closely with shafts, housings, fits, and mounting interfaces. A simplified representation improves legibility, especially in complex assemblies, while still preserving the key spatial and functional cues needed to understand the design.

Position within the ISO 8826 family

This document is Part 2 of the ISO 8826 series and specifically deals with detailed simplified representation. It belongs to the broader field of technical drawing conventions for machine elements, and it should be understood as a drawing-language standard rather than a product-performance or bearing-design specification.

• Detailed simplified graphical representation of rolling bearings
• Applicable to various bearing types in technical drawings
• Aims to improve clarity and standardised communication
• Supports interpretation of bearing placement and assembly context
