FAQ
What is the main advantage of the ‘K’ suffix on the NAH20ANZ-K?
The ‘K’ suffix indicates the presence of an NSK K1 lubrication unit. This is a porous, oil-impregnated resin that provides a continuous supply of lubricant to the ball bearings, ensuring long-term maintenance-free operation and extending the service life of the guide block.
Can this NAH series block be used on a rail intended for the newer NH or NS series?
No, the NAH series has different mounting dimensions and profiles compared to the newer NH and NS series. It is crucial to use this block only with a compatible NAH series 20mm rail to ensure proper function and accuracy.
What type of preload does the ‘Z’ in the model number indicate?
The ‘Z’ signifies a slight preload. This means the internal clearance between the balls and the raceway is eliminated, resulting in increased rigidity and higher accuracy, which is suitable for applications that require precise positioning and minimal deflection under load.
