Overview

SIST ISO 6743-2:2002 is an international standard developed by the International Organization for Standardization (ISO) that specifies the detailed classification of lubricants and industrial oils specifically for Family F, which includes spindle bearings, bearings, and associated clutches. This part of the ISO 6743 series focuses on the classification system for lubricants used in these critical mechanical components and serves as a supplement to the general principles outlined in ISO 6743-0.

The standard provides uniform coding and categorization of lubricants, helping industries identify and select the correct type of oil or grease for spindle and bearing lubrication. The classification supports improved equipment performance, longevity, and reliability by ensuring the proper selection of lubricants tailored to the function and operating conditions of spindle bearings, bearings, and clutches.

Key Topics

  • Classification Structure
    The standard classifies lubricants in Family F using a coding system beginning with the letter "F" to designate the product family. Each lubricant type is further categorized based on composition, properties, and typical applications-such as oils with anti-corrosion or anti-oxidation additives appropriate for smooth bearings or clutch parts.

  • Lubricant Types
    Lubricants covered include mineral oils with enhanced properties (e.g., anti-wear, anti-oxidation, anti-corrosion) suitable for circulating oil lubrication and bath lubrication systems. The standard identifies codes such as FC and FD representing specific product categories within Family F.

  • Viscosity Classes
    The classification system integrates viscosity grades following ISO 3448, enabling precise designation of lubricants such as ISO-L-FD 68 or its abridged version L-FD 68, where the number denotes the viscosity grade according to ISO standards.

  • Application Areas
    The standard targets lubricants used in spindle bearings, smooth bearings, rolling bearings, and clutches, offering guidance on selecting products that ensure efficient lubrication under mechanical stress and temperature variations.

Applications

SIST ISO 6743-2:2002 is crucial in various industrial sectors where spindle bearings, bearings, and clutches are present:

  • Machine Tools
    Ensures spindle bearings are lubricated with appropriate oils, reducing wear and improving precision machining.

  • Automotive and Heavy Machinery
    Standardized oils from this classification improve reliability in engines and transmission clutches.

  • Manufacturing Equipment
    Bearings and associated clutches in conveyor systems and production lines benefit from lubricants selected following this standard.

  • Power Generation
    Bearings in turbines and rotating equipment require oils that meet the classification criteria for durability and performance.

Adopting this standard helps maintenance teams and engineers select the right lubricants, reduce downtime, and optimize equipment lifecycle costs.

Related Standards

  • ISO 6743-0
    Provides the general framework and system for classifying lubricants, to be used in conjunction with ISO 6743-2.

  • ISO 3448
    Defines viscosity grades for industrial liquid lubricants, referenced for viscosity classification within ISO 6743-2.

  • ISO/TC 28
    The technical committee responsible for petroleum products and lubricants, overseeing the development of related standards.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national Standards is carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 6743/Z was developed by Technical Committee
ISO/TC 28, Petroleum products and lubricants, and was circulated to the member
bodies in August 1980.
It has been approved by the member bodies of the following countries :
Australia Germany, F. R. Poland
Austria Hungary Romania
Belgium India Spain
Brazil Iran Sweden
Israel Switzerland
Bulgaria
Canada Japan Turkey
