Full title and description

GOST 520-2011 — Rolling bearing. General specification (original Russian title: «Подшипники качения. Общие технические условия»). The standard establishes general technical requirements, marking, packing, storage, testing and acceptance rules for rolling bearings used in machinery and equipment.

Abstract

GOST 520-2011 is a consolidated technical specification that sets out the general conditions for design, manufacture, testing, marking, packaging and storage of rolling bearings. It defines accuracy (quality) classes, basic dimensional and tolerance principles, acceptance and documentation requirements applicable to a wide range of ball and roller bearings intended for industrial use.

General information

• Status: Active / current (in force).
• Publication date: Adopted as GOST 520-2011; published/issued in official collections July 1, 2012 (commonly cited publication date for the 2011 edition).
• Publisher: Russian national standards system (published under the GOST framework; distributed through Rosstandart and authorized publishers/distributors such as Interstandard/Intertek and commercial standards houses).
• ICS / categories: 21.100.20 — Mechanical systems and components; bearings.
• Edition / version: Designation GOST 520-2011 (2011 edition / current edition with later errata published 2013).
• Number of pages: Approximately 70–71 pages depending on publisher/translation.

Scope

GOST 520-2011 applies to rolling bearings of various types (ball and roller bearings) and sets the general technical requirements that manufacturers, suppliers and users must follow. The scope covers definitions and terminology, designation and marking rules, accuracy (quality) classes, basic dimensional and tolerance principles, materials and heat treatment references, rules for conservation and packaging, storage and transport requirements, methods of acceptance and inspection, and documentation (passports, certificates). It serves as the general technical backbone; specific bearing types and detailed dimensional standards remain covered by type-specific GOST/ISO standards.

Key topics and requirements

• Designation and marking of bearings (including indication of accuracy/quality class and additional marks).
• Accuracy (quality) classes and tolerances (normal, 6, 5, 4, T, 2 and additional classes where applicable).
• Dimensional and geometric requirements referenced to type-specific standards and international rules for bearing tolerances.
• Requirements for packaging, conservation (anti-corrosion protection), labelling and storage conditions to preserve bearing quality.
• Acceptance, inspection and testing procedures; documentation/passport data required with shipments.
• Interchangeability and reference to prior national standards (guidance on replacing older GOST documents).

Typical use and users

Manufacturers of bearings and bearing assemblies, mechanical designers and OEMs (machinery and equipment builders), procurement and quality assurance teams, test laboratories and maintenance/repair departments use GOST 520-2011 as the baseline specification for general requirements that complement type-specific dimensional and performance standards. National/regional standards offices and importers use it for conformity assessment and procurement specifications.

Related standards

GOST 520-2011 updates and replaces earlier national versions (for example, it supersedes GOST 520-2002 in the sequence of national documentation) and is used together with type-specific GOST/ISO standards for dimensions and tolerances (examples: GOST documents for particular bearing types and international standards such as ISO 15 / ISO 492 for bearing dimensions and tolerances). Distributors and publishers may also issue errata/corrigenda (e.g., the 2013 errata).

FAQ

Q: What is this standard?

A: GOST 520-2011 is the Russian GOST standard titled "Rolling bearing. General specification" that defines general technical requirements, marking, packaging, storage and acceptance rules for rolling bearings.

Q: What does it cover?

A: It covers general technical conditions applicable to a wide range of rolling bearings: terminology, designation and marking rules, accuracy/quality classes, general dimensional/tolerance principles (with references to type-specific standards), packaging/conservation and storage requirements, acceptance and documentation. For detailed dimensions and performance of a specific bearing type, use the corresponding type-specific GOST or ISO standard.

Q: Who typically uses it?

A: Bearing manufacturers, mechanical designers and OEMs, procurement and QA departments, test laboratories, maintenance and repair teams, and national standards bodies or regulatory organizations involved in conformity assessment.

Q: Is it current or superseded?

A: The 2011 edition (published in official collections around July 1, 2012) is treated as the current/general technical specification; publishers also list an errata release (2013). Always check with the national standardization body or authorized distributor for the absolute latest status or amendments before using the text in regulated procurement.

Q: Is it part of a series?

A: GOST 520-2011 is a general (umbrella) specification for rolling bearings and is intended to be used alongside type-specific GOST and international standards (ISO) that provide detailed dimensional and tolerance tables for particular bearing types. It continues the sequence of national bearing standards (replacing earlier editions such as GOST 520-2002).

Q: What are the key keywords?

A: Rolling bearing; bearings; tolerances; accuracy class; marking; packaging; conservation; storage; acceptance; GOST 520-2011.
