The Vacuum heat-treatment, advanced equipments and mature techniques are to ensure the quality of products. They are of high accuracy, excellent capability and longer lifetime. Different materials can be selected according to the specific situations.
Ball retainers are using the super accurate steel-ball, so the out-of-roundness reaches to 0.25μm. Especially, the high-rigidity guide posts & bushings, the ranking density of ball retainers are as 1.7 times as common ones, extending the life of products apparently. At the same time, we’ve achieved Zero-clearance installation by using Interference-fit.
