GOST 3722-2014 PDF

Full title and description

GOST 3722-2014 — Подшипники качения. Шарики стальные. Технические условия (English: Rolling bearings. Steel balls. Specifications). The standard establishes technical requirements, dimensions, accuracy grades, inspection and marking, packaging and storage rules for steel balls used in rolling bearings and as separate parts.

Abstract

This national standard defines the specifications for manufacture, acceptance testing and documentation of steel bearing balls: nominal diameters, material grades (commonly high‑carbon chrome steels such as ШХ15), accuracy classes, surface and geometric quality limits, mechanical properties and requirements for packaging, storage and marking. It harmonises national practice with the relevant international reference (ISO 3290 series) and replaces the previous edition (GOST 3722-81).

Scope

The standard applies to steel balls used in rolling bearings and to steel balls supplied as individual parts. It sets requirements for nominal diameters, dimensional and geometric tolerances, accuracy grades, material and heat‑treatment characteristics, surface condition, inspection methods, marking, packaging, storage and manufacturerʼs documentation. Deviations by agreement between supplier and purchaser are allowed for balls manufactured as separate items.

Key topics and requirements

• Nominal diameters and permitted size ranges for bearing balls (standard nominal sizes as listed in the standard).
• Accuracy/grade classes (G‑grades such as G5 … G1000 or similar classification used for roundness/size tolerances).
• Material and heat‑treatment requirements (commonly high‑carbon chromium bearing steels such as ШХ15 and equivalent specifications).
• Surface quality, sphericity and geometric tolerances, and allowable defects (cracks, laps, seams, pits) with inspection criteria.
• Mechanical properties and hardness limits after heat treatment.
• Sampling, acceptance and control methods, including reference test procedures.
• Marking, packing, transportation and storage requirements to protect ball quality in delivery and storage.
• Conformity documentation and manufacturerʼs warranty/traceability data to accompany supplied batches.

Typical use and users

Primary users are bearing manufacturers and component suppliers, metallurgical and precision‑parts producers, quality and testing laboratories, OEM procurement and inspection departments, and customs/standards compliance teams. The standard is also used by distributors and purchasers of steel balls for maintenance, repair and industrial applications where interchangeability and measured performance are required.

Related standards

GOST 3722-2014 is aligned with international practice and references/relates to: ISO 3290 (series) — steel balls for bearings (ISO 3290‑1:2008 is commonly cited), the older national edition GOST 3722-81 which it replaces, and various GOST documents on testing, surface preparation and material standards referenced within its normative list (examples include other GOSTs for hardness, surface roughness and packaging).
