الفوائد الرئيسية لعمليات الشاحنات

    متانة شديدة التحمل

    : بناء من فولاذ المحامل يقاوم التآكل تحت الأحمال الشعاعية العالية، مما يطيل عمر الخدمة في نواقل الحركة والمحاور الخاصة بالشاحنات.

    تصميم موفر للمساحة

    : أبعاد مدمجة 85×120×35 مم تعمل على تحسين التثبيت في حجرات المحرك الضيقة.

    أداء دقيق

    : تضمن درجات الدقة المتعددة (P0-P2) دورانًا سلسًا وتقليل الاهتزاز.

    تشحيم مرن

    : متوافق مع الشحم أو الزيت ليتكيف مع ظروف التشغيل المتنوعة.

تطبيقات

مناسب تمامًا لعلب التروس للشاحنات، وأنظمة التفاضل، ومحاور العجلات—المكونات الحيوية التي تتطلب دعمًا موثوقًا للحمل الشعاعي وأقل صيانة.
