Overview
ISO 6282:2018 specifies a laboratory method for determining the σ0,01‑limit* (sigma 0,01*‑limit) - the compressive hoop stress in the steel backing of metallic thin‑walled multilayer half bearings that produces a permanent set of about 0.01% in the peripheral direction. The procedure is intended for bearings with diameters up to 80 mm and may be applied to bearings up to 160 mm. ISO 6282:2018 is aimed at consistent, repeatable measurement of elastic/plastic behaviour of the steel backing in thin‑walled plain bearings.
Key Topics and Requirements
- Scope and definitions
- Determines the σ0,01*‑limit for the steel backing of thin‑walled multilayer half bearings; σ0,01* is distinguished from conventional yield limits due to specimen geometry and load method.
- Apparatus
- Pressure testing machine (hydraulic or pneumatic) with a load indicator accurate to ±1% (or better) and a length measuring device.
- Master shell and checking block (referenced in the standard’s Figure 1).
- Specimen preparation
- Prefer testing half bearings ready for mounting; if necessary, reduce width (excluding locating nick).
- Steel backing surface should be clean but not aggressively degreased; residual manufacturing lubricants acceptable.
- Test environment
- Measuring temperature 20–25 °C; test equipment and specimens must be at the same temperature.
- Procedure
- Sequence of preload, measurement and incremental compressive loading using master shell and checking block to induce and measure peripheral length reduction.
- Incremental compressive‑stress steps must not exceed 50 MPa when approaching the 0.01% permanent set.
- Results
- Use the evaluation sheet (Annex A) to record load, compressive stress (F/S), measured length reduction and determine σ0,01*‑limit.
Applications and Users
- Useful for bearing manufacturers, materials and metallurgical engineers, and test laboratories validating thin‑walled half bearing performance.
- Employed in quality control, material selection and design verification for applications in automotive, industrial machinery, and other sectors using plain bearings where thin‑walled multilayer constructions are used.
- Helps OEMs and suppliers ensure consistent load capacity and dimensional stability of bearing assemblies under compressive hoop stress.
Related Standards
- ISO 3548‑1, ISO 3548‑2, ISO 3548‑3 (thin‑walled half bearing measurement and tolerances)
- ISO 4383 (multilayer materials for thin‑walled plain bearings)
- ISO 4385 (compression testing of metallic bearing materials)
Keywords: ISO 6282:2018, plain bearings, thin‑walled half bearings, σ0,01*‑limit, compressive hoop stress, testing procedure, checking block, master shell, bearing diameters.
