أوقف تأخيرات الإنتاج باستخدام المحمل الكروي الدفعي الأصلي
51101
غالبًا ما تواجه فرق المشتريات في قطاعي السيارات والآلات توقفًا غير متوقع في خطوط الإنتاج بسبب فشل المحامل المبكر. المحامل الدفعية المقلدة تفشل كثيرًا في غضون أسابيع تحت الحمل المحوري، مما يتسبب في أضرار متتالية للمكونات المجاورة وتكلف آلاف الدولارات من التوقف غير المخطط له. قنوات التوزيع متعددة المستويات تفاقم المشكلة، مما يطيل أوقات التسليم بنسبة 30-50% عندما تكون قطع الغيار مطلوبة بشدة في أسرع وقت.

محمل 51101: متوفر في المخزون ويمكن تتبعه
As an official NTN distributor, we eliminate these risks with direct access to the manufacturer’s supply chain. The NTN 51101 thrust ball bearing is currently in stock, available for immediate shipment with complete traceability documentation—critical for customs clearance and quality compliance. Our three-level ISO 9001 inspection process ensures each bearing meets OEM specifications, whether for motor end caps in manufacturing plants or transmission systems in automotive production.
الأداء الأمثل في تطبيقات الأحمال المحورية
تم تصميم محمل الدفع
51101 لتحمل الأحمال المحورية النقية في التطبيقات أحادية الاتجاه. بقطر تجويف 65 مم، وقطر خارجي 100 مم، وعرض 47 مم، فإنه يوفر أداءً موثوقًا في الآلات التي تعمل بسرعات معتدلة وظروف دفع ثابتة. يتيح تصميمه المنفصل سهولة التركيب والصيانة، وهي ميزة أساسية في المعدات التي يجب فيها تقليل وقت التوقف عن العمل.
الميزات التقنية التي تضمن الموثوقية
Precision ratings from P0 to P2 accommodate diverse application requirements—P2 grade for high-precision motor assemblies demanding minimal runout, and P0 for general machinery where cost-efficiency matters. The bearing’s 0° contact angle optimizes load distribution for axial forces, while Z1V1 to Z3V3 vibration classes allow selection based on noise sensitivity. Constructed from high-grade bearing steel, it maintains structural integrity under continuous operation, supported by either grease or oil lubrication to match specific operating environments.
التكلفة الإجمالية للملكية: لماذا الأصالة مهمة
While gray market bearings may offer lower upfront prices, their hidden costs quickly outweigh savings. A single counterfeit NTN 51101 bearing can cause equipment failure leading to production losses, emergency repair fees, and potential damage to expensive machinery. Our genuine bearings, backed by NTN’s manufacturing standards, reduce total cost of ownership through longer service life, predictable performance, and elimination of liability risks from non-compliant components.
