Product Parameter (Specification)

Product Feature And Application

Tangshan Yuexin Machinery Manufacturing Co., Ltd.'s Bearing Housing Fabrication has significant advantages in materials, sealing, precision, and operation and maintenance. Made of ductile iron, after aging treatment and surface powder coating, the tensile strength is ≥450MPa, and the corrosion resistance is improved by 30%. It innovatively adopts a double-lip oil seal + labyrinth gap dual-sealing structure, which effectively prevents metallurgical dust, steel slag particles, and cooling water from entering, extending the bearing's service life by more than 50%. The mounting holes are precision machined on a CNC boring machine, with the hole diameter tolerance controlled at H7 grade, ensuring a ≥99% fit with the bearing outer ring and preventing axial movement during operation. It supports both oil lubrication and grease lubrication options, and includes a pre-reserved oil filling hole and oil level observation window for easier maintenance.

Our products have a wide range of applications, including heavy industries such as steel, mining, and building materials. For example, our metallurgical conveyor roller bearing housings can withstand high-temperature billet conveying environments up to 1200℃, protecting the roller bearings from heat radiation and dust. Our rolling mill bearing housings are used to secure the work rolls and support rolls of the rolling mill, withstanding high-frequency impact loads during rolling. Our mining machinery bearing housings are compatible with the transmission systems of crushers and conveyors, ensuring stable operation even in high-dust, heavy-load environments.

Yuexin Machinery's Bearing Housing Fabrication process is strictly controlled from start to finish, following a process of "material smelting - precision machining - sealing assembly - performance testing" to ensure stable and reliable product quality. During smelting, ductile iron is treated in a medium-frequency induction furnace, and rare earth elements are added to optimize the metallographic structure, fundamentally avoiding casting defects such as porosity and sand holes. In the machining stage, CNC lathes and boring machines work together, controlling the roundness error of mounting holes to ≤0.01mm and the parallelism of end faces to ≤0.02mm/m, ensuring assembly accuracy meets standards.

During sealing assembly, the oil seal and seat body use an interference fit, while the labyrinth clearance is precisely controlled within 0.2-0.5mm, ensuring sealing effectiveness while avoiding frictional heat generation. The testing stage rigorously performs hydrostatic sealing tests (pressure 0.3MPa, pressure held for 30 minutes without leakage) and load impact tests to comprehensively verify the product's stability under extreme operating conditions.
