Our range covers carbon, chrome and stainless steel balls, ceramic, glass and plastic balls, grinding and burnishing media, and ball transfer units, in standard and custom specifications.
For more than five decades, STR Industries has supported customers in industrial, automotive, medical, defense and food processing markets. We start from your drawing, datasheet or application notes and help you choose the material, size, grade and finish that fit the job, then quote it.
Our products are supplied under ISO 9001 and TS 16949 / IATF 16949 quality management systems that support traceability, inspection and documentation. Material certifications, dimensional inspection reports and certificates of conformance are available on request.
Balls can be specified to recognized standards, including ABMA, ANSI/ABMA, ISO 3290, ASTM F2215 and DIN 5401, depending on the material, application and tolerance requirement.
We do not publish a price list, because the right answer depends on size, material, grade, quantity and lead time. Send us your requirements and an STR specialist will come back with a quote and any recommendations.
