Excuse me, what do you mean by interchangeability and non interchangeability?
The interchangeability of sliding blocks between different rails is called interchangeability
When it comes to the rail and the slider interchangeability of global do the strongest is the German BOSCH Rexroth (BOSCH REXROTH) linear products. He can assemble any product with the same specifications, different clearances or shapes, with the same accuracy. There is a agent in Southern China district. It seems to be in Foshan. Would you please check it?. It's called Shunde Derun bearing
The so-called interchangeability and non interchangeability, refers to the guide rail and slider type representation.Non reciprocal type: refers to the guide rail and the slider combination in the representation of the non reciprocal type for instance CSK brand: LMG20H-2SSPO+R2000N the linear guide rail length is said there is only 2000 block equipped with 2 square high assembly (I assembled the representation is a brand of high block: LMG20HSSPON), and can not change slide into other types.Swap type: refers to the guide rail and the slider respectively because there are a variety of slide style, with a guide rail can be equipped with slide blocks with different sizes, the above example is expressed as: LMG20+R2000N slider guide said: LMG20HSSPON.
