RGH SERIES CARRIAGES

HIWIN RG Series Roller Rail Guides employ cylindrical rollers instead of
Steel balls, which deform under heavy loads. Mainly used in metal
Working machine tools, they offer greater rigidity, higher load capacity,
Longer service life, and ability to downsize to a smaller rail size while
enhancing performance.
Following the same sizing model as the HG series, RG series linear
guides. Due to their ability to withstand much heavier loads, RG rails
have double the bolt holes. So, in order to optimize their performance
you will need to add bolt holes to the rail mounting surface. The same
principle applies to RG Series carriages, which have six mounting holes
instead of four.
