Linear guideway EGH Square type.
EG series of guideways offer a low profile, high load capacity, and high rigidity. They also feature an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length makes the EG series more suitable for high-speed automation machines and applications where space is limited. The retainer is designed to hold the balls in the block even when it is removed from the rail.
