Rodamientos de agujas, componentes diseñados con precisión, se utilizan ampliamente en diversas industrias debido a su capacidad para soportar altas cargas radiales en un espacio limitado. La selección correcta de los rodamientos de agujas es esencial para garantizar el rendimiento y la vida útil óptimos de los equipos mecánicos.

The needle roller bearing size chart is a comprehensive reference guide that provides important information about different types and sizes of needle roller bearings. It generally includes key parameters such as inner diameter, outer diameter, width and load capacity. The size chart may also provide other details such as limiting speed, tolerance class and available variations of cage design and materials.

The structure of needle roller bearings is diverse, and the scope of application is also different as follows:

Diferentes tipos de rodamientos de agujas personalizados:

1. Rodamientos de agujas con aro exterior estirado. Este tipo de rodamiento tiene dos tipos: perforado y sellado. El rodamiento de agujas con aro exterior estirado no tiene aro interior y la aguja entra directamente en contacto con la superficie del eje, por lo que la precisión del mecanizado y la dureza del tratamiento térmico del eje deben ser las mismas que las del aro interior del rodamiento.

Ámbito de aplicación: Los rodamientos de agujas con jaula son adecuados para alta velocidad y cargas pesadas, y se utilizan principalmente en cajas de cambios o maquinaria textil de máquinas herramienta, automóviles y motocicletas.

Drawn cup needle roller bearings without cages are suitable for oscillating working conditions under heavy loads because they are filled with needle rollers. Such as the frame of the aircraft, the shaft end of the main wing of the missile, etc.

2. Solid ring needle roller bearings. Commonly used solid ring needle roller bearings are NA type and RNA type.

Scope of application: It is mostly used in machine tools, automobile gearboxes, and its advantages are small radial cross-sectional size and large radial load.

Standard solid ring needle roller bearings have cages, so the speed is higher and can meet the requirements of machine tools and gearboxes.

3.Caged needle roller bearings are suitable for printing machinery, pasture machinery, agricultural machinery, rollers for NC equipment guide rails, conveyor lines, etc.

4. Needle roller and cage assembly. The needle roller and cage components are actually needle roller bearings without ferrules. The scope of application: mostly used for the large and small ends of connecting rods for automobiles and motorcycles.

As the internal temperature of the air box rises, the bearings must be resistant to high temperatures.
