Advantage of knuckle joint over other types of joints?

i goggled and found few points.. hope they are correct!! 😀
• High repeating accuracy even with
varying material thicknesses and
tensile strengths
• Reduced impact shock thanks to
system rigidity
• Low impact noise and reduced
noise levels
• Long tool life
• High stroke rates even for complex
formed parts
• High levels of uptimes
• Lifetime lubricated roller
guiding of the slide
• Optimised slide motion as a result of
the modified knuckle-joint drive
• Stroke height infinitely adjustable at
the operator panel

great.. a special thanks for ur reply sister....
