The industry`s most well-established production network enables us to respond to various customer needs, local procurement, quick delivery, and superior customer support.

Our manufacturing network enhances our ability to manage production and inventory to meet rapidly changing customer needs for various ball/roller sizes and grades in significant quantities. This is our competitive advantage over smaller producers and supports our major customers as they expand their manufacturing operations.

Superior quality and processing technologies based on in-house manufacturing equipment and accumulated know-how

For decades, we have focused on achieving the highest quality in the production of precision balls and rollers(rolling elements). Rolling element quality is essential to the quality of end products. We strive to constantly increase the quality of our products and achieve virtually zero defects. In refining our manufacturing processes, we have developed in-house both proprietary grinding machines to achieve sphericity and our own inspection machines to ensure consistent quality for our customers.
