Structural bearings - Part 2: Sliding elements
This European Standard specifies the characteristics for the design and manufacture of sliding elements and guides which are not structural bearings but only parts of them for combination with structural bearings as defined in other Parts of this European Standard.
Suitable combinations are shown in Table 1 of EN 1337-1:2000.
Sliding surfaces with a diameter of the circumscribing circle of single or multiple PTFE sheets less than 75 mm or greater than 1500 mm, or with effective bearing temperatures less than -35°C or greater than 48°C are outside the scope of this European Standard.
Sliding elements for use as temporary devices during construction, for example during launching of the superstructure, are also outside the scope of this European Standard.
In this standard the specification is also given for curved sliding surfaces which are not part of separate sliding elements but which are incorporated in cylindrical or spherical PTFE bearings as per EN 1337.
NOTE The general principles detailed in this European Standard may be applied for sliding elements outside this scope, but their suitability for the intended use should be proven.

General Information

Overview
EN 1337-2:2004 is the CEN European Standard that defines the design and manufacturing characteristics for sliding elements and guides that are parts of structural bearings (but are not complete bearings themselves). The standard covers flat and curved sliding surfaces using materials such as PTFE (polytetrafluoroethylene), composite materials, hard chromium plated steel, austenitic steel and certain aluminium alloys. It sets performance limits, test requirements and production controls to ensure reliable, low‑friction movement in structural applications.
Key Topics and Requirements
- Scope & exclusions
- Applies to sliding elements combined with other EN 1337 bearing parts (see EN 1337-1 combinations).
- Excludes PTFE sheet assemblies with circumscribing diameters <75 mm or >1500 mm, and operating temperatures below –35 °C or above +48 °C.
- Temporary sliding devices used only during construction (e.g., launching) are excluded.
- Functional requirements
- Limits on coefficients of friction for short‑term and long‑term tests (values vary by material and temperature). Typical ranges specified are roughly 0.01–0.05 depending on material pairing and temperature.
- Verification by standardized friction tests (see Annex D) is required-mechanical/physical properties alone are not sufficient.
- Materials & components
- Requirements for PTFE sheets, composite materials (CM1/CM2), backing plates, hard chromium layers, lubricants and mating surfaces.
- Tests and acceptance criteria for plating, anodizing, lubricant stability/separation and adhesive bonds are included in normative annexes.
- Manufacture, assembly and tolerances
- Design and manufacturing tolerances, assembly procedures, and backing plate deformation calculations (Annex C).
- Conformity, installation & inspection
- Factory Production Control (Annex K), conformity evaluation, installation guidance and criteria for in‑service inspection are addressed.
Applications and Who Uses This Standard
- Primary application: bridge bearings and bearing components where controlled sliding movement is required.
- Target users:
- Structural and bridge engineers specifying bearings for buildings and bridges.
- Bearing manufacturers and fabricators producing PTFE sliding elements, plated backs, and composite guides.
- Contractors and installers performing bearing installation and assembly.
- Inspection and maintenance teams verifying in‑service performance and conformity.
- Benefits: ensures predictable friction behavior, interchangeability with other EN 1337 components, improved durability and safety in structural movement systems.

- Other EN 1337 parts: Part 7 (spherical/cylindrical PTFE bearings), Part 10 (inspection & maintenance), Part 11 (transport, storage, installation)

EN 1337-2:2004 is a European Standard that specifies the design and manufacture characteristics of sliding elements and guides. These are not structural bearings on their own, but are combined with structural bearings as defined in other parts of the standard. The standard provides suitable combinations for these elements as shown in Table 1 of EN 1337-1:2000. There are certain limitations to sliding surfaces that fall outside the scope of this standard, such as those with a diameter less than 75 mm or greater than 1500 mm, or with bearing temperatures below -35°C or above 48°C. The standard also does not cover sliding elements used as temporary devices during construction. Curved sliding surfaces are included in the standard, specifically those incorporated in cylindrical or spherical PTFE bearings as per EN 1337. It is worth noting that the general principles outlined in this European Standard can also be applied to sliding elements outside its scope, but suitability for the intended use should be demonstrated.
