Wholesale Glass Balls: ISO-Certified Supplier for Optical & Industrial Applications

Our Role: Sourcing + Quality Verification + Delivery Responsibility

What we provide as your glass ball supply partner:

• Qualified manufacturer sourcing: Direct relationships with ISO 9001/ISO 3290-certified glass sphere producers holding verified production capabilities

• Incoming quality control: 100% dimensional inspection using calibrated metrology equipment (measurement reports provided with each shipment)

• Material traceability: Full lot documentation from raw glass material through final inspection, including composition analysis certificates

Customized Glass Balls: Tailored Specifications

Beyond standard materials, we coordinate custom-manufactured glass spheres through our manufacturing partners:

Custom specifications require technical feasibility review. Minimum order quantities typically start at 10,000-50,000 pieces depending on complexity. Lead times: 4-8 weeks after specification approval.

Precision Grade Standards: ISO 3290-1:2014 Reference

Standard specification basis: Our glass ball precision grades reference ISO 3290-1:2014 (Rolling bearings – Balls – Part 1: Steel balls) dimensional tolerances, adapted for non-metallic spheres. Customers specifying other standards (ABMA Std 10, DIN 5401, or GB/T 308) should indicate preferred standard at quotation stage for proper tolerance mapping.

Critical measurement parameters defined:

• Nominal diameter tolerance (Dw): Deviation of actual diameter from specified nominal size

• Batch diameter variation (Vdws): Difference between largest and smallest mean diameters within a production lot

• Single ball diameter variation (Vdwl): Difference between largest and smallest diameters on a single sphere

• Sphericity deviation: Maximum radial distance from true spherical form

• Surface roughness (Ra): Arithmetic mean deviation of surface profile

ISO Grade	Dw Tolerance	Vdws (Batch)	Vdwl (Single)	Sphericity	Ra Surface	Common Use Cases
G10	±2.5 μm	≤0.5 μm	≤0.25 μm	≤0.25 μm	≤0.025 μm	Optical coupling, precision valves
G16	±2.5 μm	≤0.8 μm	≤0.4 μm	≤0.4 μm	≤0.032 μm	Medical devices, sensors
G24	±2.5 μm	≤1.2 μm	≤0.6 μm	≤0.6 μm	≤0.05 μm	Industrial valve components
G48	±5.0 μm	≤2.4 μm	≤1.2 μm	≤1.2 μm	≤0.08 μm	Grinding media, mechanical systems
G100	±12.5 μm	≤5.0 μm	≤2.5 μm	≤2.5 μm	≤0.125 μm	General industrial applications
G200	±25.0 μm	≤10.0 μm	≤5.0 μm	≤5.0 μm	≤0.20 μm	Low-precision fluid control
G500	±50.0 μm	≤25.0 μm	≤13.0 μm	≤13.0 μm	–	Mixing, agitation media

Important notes:
