Our bearing steel drilled balls are precisely manufactured from high carbon chromium steel GCr15 (AISI 52100), providing excellent hardness, wear resistance, and dimensional accuracy. Each ball undergoes CQI-9 compliant heat treatment (quenching?+?tempering) to ensure uniform microstructure and superior mechanical performance.

These precision bearing drilled steel ball components are widely used in automotive assemblies, precision machinery, valve systems, and cosmetic packaging, where high strength and consistent quality are critical. We also offer custom bearing steel ball solutions to meet specific design requirements, serving applications that demand reliable steel bearing balls with tight tolerances.

Full range of precision balls from one source

From bearing steel balls (GCr15 / AISI 52100) to stainless steel, aluminum, carbon steel, and specialty balls, Eurasian can support multiple projects with a single consolidated supply base. This enables you to simplify supplier management, align quality standards, and reduce total procurement and logistics costs while sourcing precision bearing steel ball and custom bearing steel ball solutions.

Experience with global OEM and export customers

We supply precision balls for automotive seat systems, wheel bearings, industrial machinery, and other export applications through long-term cooperation with overseas customers. Our team is familiar with international documentation, packaging, and inspection requirements, making sourcing steel ball bearing balls or drilled balls smoother, more reliable, and predictable.

Stable capacity and flexible cooperation

With established production lines and daily output measured in tons, Eurasian can support both trial orders and high-volume programs with dependable lead times. Flexible MOQs, customized packaging, and responsive communication make it easier to introduce drilled or precision balls into new projects while controlling risk and delivery schedules.

Q1: What is a drilled steel ball?

A drilled steel ball is a precision bearing steel ball featuring a hole, either through or blind. The hole facilitates easier assembly, weight reduction, or fastening for mechanical or decorative applications.

Q2: What materials do you use?

We primarily use GCr15 (AISI?52100 / 100Cr6), a high-carbon chromium steel renowned for hardness, wear resistance, and dimensional accuracy, producing precision bearing steel ball components suitable for demanding applications.

Q3: Can you customize the hole size and depth?

Yes. We manufacture drilled balls with through-holes or blind-holes according to your CAD drawings or sample requirements, maintaining tight tolerances for reliable assembly.

Q4: Are the drilled balls heat-treated?

Absolutely. All GCr15 drilled balls undergo CQI-9 compliant quenching and tempering to achieve HRC 60–66 hardness, ensuring consistent performance and durability.

Q5: What surface finish options are available?

We offer mirror-polished and matte finishes. Surface roughness and brightness can be customized depending on your application, whether for functional or aesthetic requirements.

Q6: Do you provide samples or small orders?

Yes. Sample or small orders are available for testing and evaluation before bulk production, supporting prototypes or low-volume programs for custom bearing steel ball requirements.

Q7: What certifications does your factory hold?

Our factory is certified to IATF?16949:2016, BV, GMPC (US), and ISO?22716, ensuring strict quality control for global clients sourcing steel bearing balls or steel ball bearing balls.

Q8: What industries use drilled balls?

Typical industries include automotive, mechanical engineering, cosmetic packaging, medical devices, and instrument calibration, where drilled stainless steel balls or bearing steel variants may be required.

Q9: How should I choose between stainless and bearing steel balls?

Choose GCr15 bearing steel when high hardness and wear resistance are critical. Choose stainless steel (440C / 304 / 316L) when corrosion resistance is a top priority.

Q10: What packaging options are available?

Standard export packaging includes anti-rust oil, PE bags, cartons, and wooden crates. Custom labeling, palletizing, and protective packaging can be arranged to meet specific logistics or application needs.
