The core technology of spherical bearings is “self-aligning adaptability + wear resistance and durability.” Core components (inner and outer rings and rolling elements) are made of high-carbon chromium bearing steel. The inner and outer rings undergo a “through quenching and low-temperature tempering” process to achieve a high-hardness martensitic structure, ensuring fundamental strength. The rolling elements undergo a “carburizing, quenching, and cryogenic treatment” process, which not only increases surface hardness but also ensures roundness and dimensional consistency.
The spherical surface is first rough-machined on a CNC lathe, followed by semi-finishing and fine-grinding on a high-precision grinder. Strict surface accuracy is achieved, achieving a surface roughness of Ra ≤ 0.2 μm. The seat of the seated bearing is machine-cast using high-precision aluminum extrusion molds that take over 100 hours to machine. After shot blasting and grinding, the surface finishes, including the bearing bore, are machined. Custom painting is also available.
Assembly is carried out in a clean workshop, with the bearings and seat bodies precisely fitted together and equipped with sealing and grease injection structures. After the finished product is tested for rotation accuracy and clearance, it can operate with low friction and a long life in scenarios where the shaft system is misaligned and is widely suitable for complex working conditions such as mining machinery and agricultural equipment.
