Made of SUS304 or SUS316 stainless steel, it is corrosion-resistant, wear-resistant, and has a high surface finish, suitable for precision polishing with high cleanliness requirements.
Excellent mechanical properties, high strength and good toughness, ensuring stability and consistency under long-term use.
The stainless steel saucer ball provides a larger contact area and efficient deburring ability with its unique saucer shape, significantly improving polishing uniformity and efficiency.
Complying with international standards, it is recyclable and environmentally friendly and is widely used in surface treatment in industries such as industry, medical treatment and jewelry.
Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.
For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100. We also offer custom specifications for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls.
High-strength inner packaging: Shockproof foam bags or custom plastic boxes are used to secure each Flying Saucer stainless steel ball in place, protecting it from impacts and scratches.
Moisture-proof protection: A moisture-proofing agent is added to effectively prevent the impact of moisture on the product during transportation.
Sturdy outer packaging: Thickened corrugated cardboard boxes or wooden pallets (for large orders) are used to ensure safe long-distance transportation.
Clear labeling: Product specifications, quantity, and drop warnings are clearly marked on the outer packaging box for easy verification and safe handling.
Common grades include:
A stainless steel flying saucer ball is a compact, disc-shaped bearing or grinding media made primarily from corrosion-resistant stainless steel (e.g., grades 304, 410, or 420). It functions as a ball transfer unit for smooth, multi-directional movement in conveyors or as polishing media for hardware surfaces. The "flying saucer" name comes from its UFO-like profile, allowing it to recess into surfaces for flush installation.
