Double-Sided Profiled Bearing Cage | Near-Net Shaping Technology for High-End Applications
The double-sided profiling process is a high-
Precision Forging technology developed based on our in-house capability to design and manufacture ring-rolling dies and tooling. This process enables the forged blank to closely match the final shape on both sides (inner and outer diameters) as well as radially, ensuring precise material distribution and meeting the demanding performance requirements of wind power, marine, and
Heavy Machinery applications.
This technology achieves precise three-dimensional shaping of the blank, making it an ideal solution for large and medium-sized heavy-duty bearings that require high reliability, long service life, and sustainable manufacturing. Our extensive experience and integrated production capabilities ensure the stability and consistency of this advanced process in mass production.
