There is only few differences HGR is the rail followed by the rail width then length. HGR20-L1500
HGH20CA is Narrow carriage
HGW20CA is wide flanged carriage.

Hi-win do offer other types with different heights and preloads etc but most of what you see for sale in China are common preload and carriage heights.
