Hopefully someone steps in that's been in school long after I was.
This never really made sense to me but here goes.
The Newton is a metric measure of force , kilogram is a measure of mass. So 1 kg on earth with gravity of 9.81 m/sec2 exerts a force of 9.81 N downward.
So 1 N = 1/9.81 Kg force or 0.10197 Kg force = .22481 pounds force.
Clear as mud, right.
Kilograms seemed to get used as force or weight regular unless it was stated as mass, which you then had to multiply by gravitational acceleration to get weight or force.
Bet this cleared it right up for you Ed. Ha

What are the ratings for? Bearings?

Yes, linear bearings. I ordered 4 from Amazon.

Impressive response Greg! (You had better go take a nap)
Or you can just cheat and look it up at Online Conversion. It's my goto conversion place.
559N = 125.7 pounds force
971N = 218.3 pounds force

Take a nap ! Remembering back that far disturbed the grey matter so bad I passed out.

Mass and weight.
The confusion arises because we use mass and weight here on earth to mean the same, however mass is not the same as weight.
If you stood on a scale here on earth and it reads 150 lbs, if you went into space and took the same scale with you and stood on them in space the reading would be zero ie. you are weightless but not mass-less you still have your mass.

True, but how do I get the scale to read only 150lbs. here on earth!
