Description

PROBOSS replacement guide roller - Part number 11990204

Original replacement guide roller manufactured by PROBOSS, commercial part number 11990204, version 2.9 in white color. This high-strength rolling element is specifically engineered to travel smoothly within the scissor suspension tracks of PROBOSS tractor and agricultural machinery operator seats. Its primary function is to ensure fluid, quiet, and bind-free vertical movement throughout the suspension stroke, supporting operator weight while minimizing friction between the moving scissor arms and the seat frame. Molded from wear-resistant, high-load technical polymer, it prevents structural play and metallic rattling. It is the ideal replacement part for worn, flat-spotted, seized, or damaged rollers, typically serviced alongside the matching version 2.9 bearing housing.

Key features
