NK21El Rodamiento de Rodillos Aguja a Prueba de Choque {{ZKF_2}}/12 está diseñado para soportar cargas pesadas y tensiones dinámicas comúnmente encontradas en la hidráulica de maquinaria de construcción. Su diseño presenta rodillos en lugar de bolas, lo que permite una mayor capacidad de carga y mejor resistencia a choques y vibraciones. El rodamiento está disponible en varios tamaños, pero el modelo {{ZKF_3}}/12 mide específicamente 25 mm de diámetro y 12 mm de ancho. Este tamaño compacto lo hace ideal para aplicaciones donde el espacio es limitado pero se requiere resistencia.{{ZKF_1}}Key parameters of the NK25/12 bearing include a load capacity of up to 5,000 kg, a speed rating of up to 10,000 RPM, and compatibility with grease or oil lubrication. The bearing’s durability is further enhanced by its double-row needle roller configuration, which distributes loads evenly across the raceways. Additionally, the bearing is treated with rust-resistant coatings to ensure longevity in harsh environments. Below is a table summarizing the main technical specifications:
The Shock Proof Needle Roller Bearing NK25/12 is commonly used in various components of construction machinery, particularly in hydraulic systems. One of its primary applications is in hydraulic cylinders, where it supports the piston rod and ensures smooth movement under heavy loads. The bearing’s ability to handle shock and vibration makes it suitable for equipment like excavators, loaders, and bulldozers, which operate in rough and dynamic conditions.
NK21Otro caso de uso común es en los sistemas de transmisión de vehículos de construcción. El rodamiento se encuentra a menudo en cajas de cambios y unidades diferenciales, donde ayuda a transmitir potencia de manera eficiente mientras soporta las tensiones de la operación continua. Su tamaño compacto también lo hace ideal para maquinaria más pequeña, como excavadoras compactas y minicargadoras, donde el espacio es limitado.{{ZKF_1}}Additionally, the NK25/12 bearing is used in mobile cranes and hoists, where it supports rotating and linear motion components. Its high load capacity and durability ensure that these machines can operate reliably even under extreme conditions. The bearing’s rust-resistant coatings also make it suitable for outdoor applications where exposure to moisture and dirt is common.

{{ZKF_0}}Soluciones para Desafíos Comunes{{ZKF_1}}One of the common challenges faced when using the Shock Proof Needle Roller Bearing NK25/12 is lubrication. Proper lubrication is essential to ensure the bearing operates smoothly and lasts longer. It is recommended to use high-quality grease or oil that is compatible with the bearing’s materials. Regular lubrication intervals should be followed to prevent wear and tear.
Another challenge is the potential for contamination. The bearing’s small size and precision make it vulnerable to dust and debris, which can cause premature failure. To mitigate this, it is important to use protective seals and keep the operating environment clean. Regular inspections can help identify any signs of contamination early on.
Additionally, overloading can significantly reduce the lifespan of the bearing. It is crucial to ensure that the bearing is used within its specified load capacity. If the application requires higher loads, it may be necessary to select a larger bearing size. Consulting the manufacturer’s guidelines can provide additional insights into proper usage and load management.
