Glass Ball

The product is a precision glass sphere offered by Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. It is manufactured from soda‑lime and borosilicate glass and is supplied in diameters ranging from 0.5 mm to 25.4 mm. The spheres are intended for applications that require chemical inertness and dimensional stability.

Soda‑lime glass provides good clarity and moderate thermal resistance, while borosilicate glass offers higher temperature tolerance and lower thermal expansion, typical qualities valued in the glass sphere market. In the industry, such spheres are commonly graded by surface finish and dimensional tolerance, with a typical diameter tolerance of ±0.01 mm and a surface roughness of Ra ≤ 0.2 µm. Suppliers often ship the balls in poly‑bags or bulk containers to protect against breakage. These typical handling methods help maintain the integrity of the spheres during transport.

Typical buyers include valve manufacturers, petroleum‑product handling equipment makers, micro‑spray pump producers and decorative item fabricators. The supplier lists no minimum order quantity or price, so interested importers should request a quotation and confirm Incoterms, payment conditions and lead‑time directly with the company. Because the supplier’s response rate is currently recorded as zero, establishing clear communication channels before placing an order is advisable.
