2Expert Interpretation
An in-depth analysis of the 2021 revisions to the DIN EN 12080/A1 railway bearing standard, covering new testing requirements for polymer cages, changes to marking requirements, and key compliance points for EU Directive 2016/797. Technical comparison tables and implementation recommendations are also provided.
Core content of the standard revision
The draft DIN EN 12080/A1 standard released in April 2021 made important adjustments to the technical requirements for railway rolling bearings, mainly involving:
- Polymer cage testing: Cancel the mandatory adjustment requirement (D.2.4)
- Marking specification: Clarify the handling method of marking deviation of cylindrical roller bearings (11.2-11.3)
- Material testing: Revise the Charpy impact test requirement to a non-notched specimen (Table D.1)
Comparison of key technical changes
| Item | Original standard requirements | Revised requirements |
|---|---|---|
| Polymer cageAdjustment | Must be completed at the cage manufacturer | Permitted at the bearing manufacturer (D.2.4) |
| Glass fiber length | Strictly limited range | Relaxed to 0.1-1.0mm (Table D.1) |
| Burr height | ≤0.2mm outside the functional area | Exceptions are allowed and a defect catalogue needs to be established (D.3.4.3) |
Key points for compliance with EU Directives
The revised Annex ZA clarifies the correspondence with EU Directive 2016/797:
- Freight truck bearings must comply with TSI 321/2013 specifications (clause 4.2.3.6.5)
- The mechanical performance requirements for locomotive bearings refer to Chapter 14 of this standard
- New material traceability requirements (6.3)
Implementation recommendations
Enterprise response measures:
- Establish a classification catalog for cage defects (D.3.4.3)
- Update bearing marking technical specifications (11.2-11.3)
- Adopt ISO 15512 as an alternative method for moisture detection (D.3.2)
- Note that the standard transition period is until May 5, 2021
