Overview

CLC/TR 60778:2004 - Brush-holders for slip-rings group R - Type RA - is a CLC technical report that gives guidance on radial brush-holders for slip-rings intended for medium-size asynchronous industrial machines of conventional construction. The report applies to machines with shaft heights in the recommended range (mm): 160, 180, 200, 225, 250, 280, 315, 355, 400. The document has the status of a technical report and is published in the CLC family (also issued as SIST-TP CLC/TR 60778:2005 in Slovenia).

Key topics

The technical report focuses on the following core aspects (as defined by its scope and classification):

• Applicability: Defines that it applies to radial brush-holders for slip-rings used on medium-size asynchronous machines (Group R, Type RA).
• Recommended shaft heights: Lists standard shaft heights in millimetres for which the brush-holders are intended: 160–400 mm (specific values provided).
• Classification and designation: Identifies the product group (R) and the specific execution (Type RA).
• Standards status: Clarifies that this document is a CLC technical report rather than a formal standard, useful for guidance and industry practice.

Note: The report is indexed under ICS 29.160.10 (Components for rotating machines).

Applications

CLC/TR 60778:2004 is relevant for professionals involved with slip-ring assemblies and rotating electrical machines:

• Design engineers specifying brush-holders for medium-size asynchronous motors and generators.
• Manufacturers of brush-holders and slip-ring assemblies ensuring compatibility with standard shaft heights and machine classes.
• Procurement and purchasing teams selecting components that conform to CLC technical guidance.
• Maintenance and reliability engineers replacing or upgrading slip-ring brush-holders in industrial equipment.

Practical use cases include retrofit selections, compatibility checks for replacement parts, and procurement specifications referencing Type RA brush-holder guidance.

Related standards

• Indexed under ICS 29.160.10 (components for rotating machines), so it should be used alongside broader CLC/IEC standards covering rotating electrical machines, slip rings, and brushes.
• As a technical report, CLC/TR 60778:2004 provides guidance that complements normative standards and manufacturer datasheets.
