Product Q&A
Q:What are the key features of the NA6904 bearing?
A:
It features a single row of precisely aligned needle rollers supported by a machined solid outer ring, providing exceptional radial load capacity in compact spaces.
Q:Is the NA6904 bearing customizable?
A:
Yes, custom configurations are available upon request, including options for needle cage guidance or full complement rollers depending on speed and load requirements.
Q:What material is used for the NA6904 bearing rings?
A:
Inner and outer rings are made from high-carbon chrome steel (e.g., GCr15 / 52100), which is heat-treated and ground for wear resistance and dimensional accuracy.
Q:What is the difference between NA6904 and RNA6904?
