Arrêtez les temps d'arrêt du moteur avec un authentique 7220 Roulement à billes à contact oblique

Les fabricants de moteurs automobiles connaissent bien la frustration : des roulements contrefaits qui tombent en panne à 30 % de leur durée de vie nominale, provoquant des arrêts non planifiés et des pertes de chaîne de production. Les distributeurs multi-niveaux allongent les délais de livraison de 30 à 50 %, obligeant les équipes de maintenance à attendre tandis que les machines restent inactives. Même les roulements authentiques manquent souvent d'une documentation de traçabilité appropriée, créant des retards de dédouanement et des risques de responsabilité qualité.

Authentiques 7220 Roulements : En stock et traçables

En tant que distributeur agréé officiel , nous éliminons ces points douloureux pour les applications de moteurs automobiles. Le roulement à billes à contact angulaire

7220 offre une longue durée de vie grâce à sa construction en acier de précision pour roulements et à sa géométrie interne optimisée. Notre inventaire en temps réel WMS garantit que ce roulement à une rangée de 100×180×34 mm est prêt pour une expédition immédiate, soutenant à la fois les séries de production planifiées et les besoins de maintenance d'urgence.

Conçu pour la performance des moteurs automobiles

Ce palier 7220 excelle dans les environnements de moteurs automobiles à haute vitesse, où les charges radiales et axiales se combinent en fonctionnement continu. La conception de joint ouvert permet une flexibilité de lubrification à la graisse ou à l'huile, s'adaptant aux exigences spécifiques de température et de vitesse du moteur. Que ce soit pour alimenter les moteurs d'entraînement de véhicules électriques ou les auxiliaires de moteurs à combustion interne traditionnels, sa conception à contact angulaire à une rangée fournit la rigidité nécessaire pour un alignement précis du rotor et une réduction des vibrations.

Détails techniques qui maximisent la durée de vie du moteur

The 7220 bearing’s 100mm bore diameter and 180mm outer diameter balance load capacity with compact installation, critical for space-constrained motor housings. At 34mm width, it offers optimal contact angle distribution to handle combined radial-thrust loads common in motor applications. Constructed from high-grade bearing steel, it maintains dimensional stability even under thermal expansion, ensuring consistent performance across the typical -40°C to 120°C operating range of automotive motors. The precision manufacturing ensures minimal runout, directly translating to quieter operation and extended motor bearing life.

Pourquoi les roulements authentiques réduisent le coût total

Choosing genuine NTN 7220 bearings over gray market alternatives delivers measurable cost benefits. Counterfeit bearings often fail within 3,000 hours of operation, while authentic NTN units typically exceed 15,000 hours in standard motor applications. This 5x life improvement eliminates repeated replacement labor, reduces production downtime, and prevents collateral damage to motor shafts and housings. Our ISO 9001 compliant quality inspection ensures each bearing meets NTN’s exacting standards, avoiding the hidden costs of premature failure.
