Labyrinth Roller Seals

The main features of the stamped housing are:   The labyrinth seal groove with concave and convex design is directly designed on the outer side, and a labyrinth seal structure is added to make the sealing effect more reliable. A sealing ring can be added to the outer end surface of the roller. The sealing ring is designed with an inwardly concave circular bevel. When the circumference is close to the circumference of the roller shaft, a labyrinth ring is raised to add a sealing cover and a sealing cover. The conventional gap is changed from the conventional roller to the interference fit. The gap in which the sealing cap and the sealing ring are embedded is left inside the circular bevel of the sealing ring which is concave. Since the gap is backward, it effectively delays the tendency of pollutants such as water and ash to enter the sealing structure;   The roller produced by the new bearing housing assembly, the labyrinth sealing cavity is filled with appropriate grease, and the water-proof and dust-proof test is performed on the simulated strengthening test bench, and the performance exceeds the national standard, which achieves the intended purpose.
