En aksel, der sendes som 40Cr, men ikke er korrekt varmebehandlet, kan have 35-42 HRC i stedet for 50-56 HRC, hvilket placerer den p\u00e5 eller under minimum for tilstr\u00e6kkelig differential mod tinbronze. For det andet, sm\u00f8remiddelproblem: EP-additiv gearolie angriber bronzehjulet. For det tredje, kontaminering: slibende partikler i sm\u00f8remidlet - selvom du identificerer og fjerner kilden, forts\u00e6tter de slibende partikler, der allerede er i olien, med at slide, indtil olien skiftes.<\/p>\n<\/div>\n<\/details>\n<details style=\"border: 1px solid #e8d8c0; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\">\n<summary style=\"padding: 16px 20px; cursor: pointer; font-size: 15px; font-weight: bold; color: #28140a; list-style: none; display: flex; justify-content: space-between; align-items: center; gap: 12px;\">Kan jeg opgradere fra et blikbronzehjul til aluminium-jernbronze for at f\u00e5 l\u00e6ngere levetid uden at skifte snekkeakslen?<span style=\"font-size: 22px; font-weight: 400; color: #c9892a; flex-shrink: 0;\">+<\/span><\/summary>\n<div style=\"padding: 0 20px 18px; font-size: 14px; color: #3d4f66; line-height: 1.82;\">\n<p style=\"margin: 0;\">Dette er den parringsfejl, der er beskrevet i h\u00e5rdhedsforskellens regel.
