1. Gestion efficace des charges unidirectionnelles
En prenant le modèle 51315 comme exemple, son chemin de roulement rectifié avec précision peut répartir uniformément la charge axiale sur la rangée de billes. Les données de test réelles montrent que sous une charge de 120 kN, l'usure de nos butées à billes unidirectionnelles est réduite de 35 % par rapport aux conceptions conventionnelles. Cette conception optimisée est le fruit d'une recherche et d'un développement conjoints avec les principaux fabricants de boîtes de vitesses automobiles, abordant spécifiquement le problème des dommages prématurés.
2. Fonctionnement à faible friction
La surface du chemin de roulement est polie (rugosité ≤0,6 μm) et grâce à une conception de courbure des billes optimisée, elle peut réduire la friction de 20 %, ce qui rend nos butées à billes unidirectionnelles très adaptées aux scénarios de fonctionnement à grande vitesse. Après avoir remplacé les roulements du dispositif d'entraînement de broche par notre modèle 51208, une usine de machines textiles en Inde a réduit sa consommation d'énergie de 12 %.
3. Performances fiables à long terme
Nos roulements sont fabriqués en acier à roulements GCr15 (dureté HRC 60-64) et subissent un processus de traitement thermique spécial, de sorte qu'ils conservent des performances stables même sous des charges à long terme. Prenons un exemple : après avoir installé nos roulements 51120 dans leurs systèmes de convoyeurs, une entreprise australienne d'équipement minier a prolongé ses cycles de remplacement de 8 mois à 18 mois.

Tests de matériaux : chaque lot d'acier est vérifié pour sa composition chimique et sa dureté (HRC 60–64).
Usinage de précision : nous utilisons des rectifieuses CNC pour garantir que la rondeur des butées à billes unidirectionnelles est maintenue à moins de 0,003 mm.
Qualité des billes : nos billes atteignent une précision G10 avec un écart de diamètre inférieur à 0,0025 mm.
• Matériaux spéciaux : Nous utilisons de l'acier inoxydable 440C. Les butées à billes unidirectionnelles ont une excellente résistance à la corrosion et sont très adaptées aux environnements marins.
• Options de lubrification : Choisissez de la graisse haute température (gère jusqu'à 180 ℃) ou un lubrifiant de qualité alimentaire certifié NSF H1.
• Conception d'installation : ils fonctionnent avec des bagues extérieures à bride ou des arbres filetés, l'installation est donc un jeu d'enfant.
• Marquage : Nous effectuons une gravure laser personnalisée, pratique pour le suivi des stocks ou le marquage.
