Structure: DOJ type constant velocity joint is composed of inner race, outer race, cage and ball. The inner race and outer are arranged in the axial direction, and the cage controls the movement of the steel ball. The center of the inner and outer spherical surfaces of the cage is symmetrically distributed relative to the center of the window, so as to realize the movement of the angle between the axes.

Features: This has the characteristics of low sliding resistance, axial movement, large sliding amount and small limit axis angle (18°), etc.
