Itu Bantalan Rol Jarum Seri NA adalah unit bantalan radial presisi tinggi yang ditandai dengan tinggi penampang rendah dan kapasitas dukung beban tinggi. Secara struktural, seri NA menggabungkan cincin luar yang dikerjakan dengan mesin, roller jarum dan rakitan sangkar, serta cincin bagian dalam yang dapat dilepas. Desain ini memungkinkan pemasangan cincin dalam dan luar secara independen, sehingga memudahkan pemasangan di rumah mekanis yang rumit. Dengan memanfaatkan roller berdiameter kecil dibandingkan panjangnya, seri NA menyediakan area permukaan kontak yang besar dalam tapak radial yang kompak. Diproduksi dari baja krom bebas gas (GCr15), bantalan ini dirancang untuk mengelola gaya radial yang signifikan sekaligus menjaga stabilitas dimensi di bawah tekanan rotasi berkelanjutan. Dimasukkannya cincin bagian dalam membuat seri ini cocok untuk aplikasi di mana poros tidak dapat dikeraskan dan digiling untuk dijadikan sebagai raceway.
