Product Overview

Stainless Steel Hollow Balls are lightweight hollow spheres engineered to deliver significant weight savings while maintaining key characteristics of corresponding solid balls, including mechanical properties, corrosion resistance, and magnetism. Engineered and tested across thousands of installations based on decades of manufacturing expertise, these hollow balls are widely selected for applications where reduced mass improves motion, buoyancy, handling, or aesthetics without sacrificing the base material advantages.

These hollow balls are produced across multiple materials and surface finishes for both industrial and decorative requirements. Because welding and polishing are done by hand, the balls have a low precision grade, making them ideal for functional and aesthetic uses that prioritize form, finish, and weight efficiency over ultra-high bearing precision.

Manufactured and supplied by SHANDONG SDBALLS INDUSTRY CORP LTD., Stainless Steel Hollow Balls are supported by an export-proven production and quality system. Shandong SDBALLS Industry Co., LTD was established based on the Shengdian Steel ball Factory. With more than 30 years of production experience, SDBALLS operates two factories covering 8,000 square meters with more than 200 sets of modern and efficient production equipment and annual steel ball production of more than 5,000 tons. Products are 100% exported and sold in more than 50 countries. As an ISO9002:2000 certified company, strict quality control is maintained throughout every manufacturing stage.
