If I have a galvanised only bollard, and I use stainless steel ring kits, does this have some effect (chemical) to gal and s/s material ?
YES! If galvanised and stainless steel properties are in direct contact and in the presence of an electrolyte (water), galvanic corrosion will occur if they are regularly exposed to an electrolyte. .
Galvanic corrosion will happens on galv ONLY in the right condition (for example: WET). It is always a good idea to separate or insulate them. You could apply some coating on the stainless steel thread to minimize the direct contact. Or use a plastic sleeve or some sort to form a barrier between them. But in the bollard case, because the galvanised portion in the product is way larger than stainless steel, it may not be a problem after all.
