Ce traitement am\u00e9liore la r\u00e9sistance \u00e0 la fatigue par flexion du pied d'engrenage de plus de 40%, ce qui rend notre support rotatif beaucoup plus r\u00e9sistant \u00e0 la rupture de dent que les concurrents similaires face aux charges d'impact \u00e9lev\u00e9es g\u00e9n\u00e9r\u00e9es par l'excavation lat\u00e9rale et le freinage d'urgence.

For more than 20 tons of excavators or need to break the hammer operation of the harsh conditions, we strongly recommend the choice of 42CrMo material, the fatigue life of more than 30% higher than 50Mn."],"faq_answer2":["A2: Our product size strictly follows OEM standards and can perfectly replace the excavator slewing bearings of Caterpillar , Komatsu , Hitachi , Volvo and other mainstream brands."],"faq_answer3":["A3: For products made of 42CrMo material, we provide a quality guarantee of 12 months or 2000 working hours from the date of installation, whichever comes first.

In view of the high torque characteristics of the excavator, our standard process includes the tooth surface induction hardening, the hardness reaches 50-60HRC. For particularly harsh working conditions, we can also provide a tooth root quenching process to further enhance the bending strength of the gear root and prevent tooth breakage."],"faq_answer6":["A6: In order to prevent rust and damage during shipping, we use three-layer protective packaging: the inner layer is coated with anti-rust oil and wrapped with anti-rust paper, the middle layer is sealed with plastic wrapping film, and the outer layer is fixed with fumigation inspection-free plywood wooden boxes.

This treatment improves the bending fatigue strength of the gear root by more than 40%, making our rotary support far more resistant to tooth breakage than similar competitors in the face of high impact loads generated by lateral excavation and emergency braking. In addition, we introduced a grinding instead of milling process in the finishing stage. Compared with the traditional hobbing process, the tooth surface roughness of the Slewbearingtec product is reduced to below Ra3.2, and the cumulative error of tooth pitch is reduced by 50%.
