GOST 4727-83 PDF

Full title and description

GOST 4727-83 — "Bearing wire. Specifications" (Russian: "Проволока подшипниковая. Технические условия"). National (interstate) standard that specifies technical requirements, material grades, mechanical and metallurgical properties, dimensional and surface requirements, packaging, marking and transport/storage rules for wire intended for bearing manufacture.

Abstract

GOST 4727-83 defines the technical conditions for production and acceptance of bearing wire produced from bearing-grade steels (for example grades based on ШХ15 and its variants). The standard covers chemical composition references, required microstructure, heat treatment (annealing), permissible non‑metallic inclusions, dimensional and surface quality, coil and roll packaging, labelling and transport/storage requirements. It includes amendments introduced after initial publication.

General information

• Status: Active (published and maintained with subsequent amendments).
• Publication date: Introduced 1 July 1984 (standard designation year: 1983).
• Publisher: State Committee for Standards of the USSR (Gosstandart) — (historical publisher); text maintained/used within successor national standards systems (Russian/CIS national standards bodies).
• ICS / categories: ICS 77.140 — products of iron and steel; wire and wire products (metallurgy / wire products).
• Edition / version: GOST 4727-83 (original 1983 adoption, effective 01.07.1984) with later amendments (examples: amendments published in 1986 and 1989).
• Number of pages: 6 (main text).

Scope

The standard applies to steel wire intended for bearing components (bearing races, balls/rollers manufacturing feedstock) and specifies the required steel grades, heat treatment state (typically annealed), permissible microstructure (fine pearlite, limitations on carbide mesh and banding), limits on non‑metallic inclusions, dimensional tolerances and surface quality, coil dimensions and weights, packaging, marking, transport and storage conditions. It is intended for manufacturers, suppliers and quality laboratories involved in production and procurement of bearing wire.

Key topics and requirements

• Designated product: bearing wire (проволока подшипниковая) and its intended application.
• Permitted steel grades and required chemical composition referencing GOST 801 (examples include ШХ15 and its variants: ШХ15-Ш, ШХ15-В).
• Heat treatment state: wire must be supplied annealed (отожжённой) unless otherwise agreed.
• Microstructure requirements: uniformly distributed fine pearlite points, strict limits on carbide mesh and structural banding.
• Non‑metallic inclusion limits specified per steel grade and acceptance tables.
• Dimensional, surface quality and tolerance criteria for nominal diameters used in bearing manufacture.
• Packaging, coil geometry and weight rules (coil inner diameter, minimum coil weight, allowed roll types, gross mass limits for coils and overpacks).
• Marking and labelling of coils (manufacturer trademark, steel grade symbol, heat/melt number, etc.).
• Requirements for transport and storage (covered transport, special conditions for deliveries to Far North, references to relevant GOSTs for packaging and storage).

Typical use and users

Primary users are bearing manufacturers, steel and wire producers, metalworking and heat‑treatment shops, procurement/specification engineers, quality control and testing laboratories, and downstream users who require bearing-grade wire for rolling and finishing into bearing elements (balls, rollers, race components). It is also used by logistics and inspection personnel for packaging, marking and transport compliance.

Related standards

GOST 4727-83 references and is typically used alongside other GOSTs covering steel chemistry, testing and packaging, for example: GOST 801 (steel grades and chemical composition), GOST 10396 (packaging/preservative oil/crepe paper), GOST 15150 (storage conditions), GOST 14192 (transport marking), and earlier/superseded national versions such as GOST 4727-67. It sits in the family of standards for bearing materials and wire products.
