Steel Ball for Particle Damper
High density precision steel ball for particle damper, made of carbon steel AISI1010 and GCr15 bearing steel. Uniform roundness, high hardness and excellent wear resistance. Used as damping medium for structural vibration control, seismic mitigation, noise and shock absorption. Custom sizes, polished surface and bulk supply available.
Our precision steel ball for particle damper is specially engineered as core damping media for passive particle damping vibration control systems, widely adopted in seismic mitigation, structural vibration suppression, mechanical noise reduction and shock absorption projects. As the key filling medium inside particle dampers, these solid steel balls dissipate vibration energy efficiently through continuous collision, friction and shear movement between balls and the inner cavity wall when excitation occurs, delivering stable broadband damping performance compared with traditional damping solutions.
We manufacture steel balls for particle damper from carbon steeel and premium GCr15 / 52100 bearing steel, with strict heat treatment to reach HRC 60–66 high hardness, outstanding density, uniform spherical geometry and ultra-low surface roughness. Each steel ball is produced and sorted under ISO 3290 precision standards, with customizable diameter ranging from 1mm to 50mm, including common sizes 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm for particle damper test samples and mass structural dampers. Consistent dimensional tolerance guarantees repeatable damping effects, avoiding performance deviation caused by uneven ball size in damper design and filling ratio calculationThis steel ball for particle damper features strong anti-wear performance, high impact resistance and stable physical properties under varying temperature conditions. It will not soften, age or lose mass quickly after long-term cyclic collision, which greatly extends the service life of particle dampers and reduces later maintenance work. Different from polymer or ceramic damping particles, high-density steel balls provide larger energy dissipation capacity under the same filling volume, making it ideal for building seismic dampers, bridge vibration control, transmission tower particle dampers, marine shafting vibration reduction, industrial equipment base dampers and test rig impact dampers.
We support flexible customization to match customer damper simulation and test requirements: adjustable precision grade, surface treatment (polished, rust-proof oil coating), mixed size grading and bulk packing. We supply steel balls for particle damper to structural engineering institutes, vibration lab researchers, damper manufacturers and construction vibration control contractors. All products go through hardness, roundness, surface inspection and sampling screening before delivery to ensure batch consistency.
If you are designing a new particle damper or replacing damping media, our steel balls can help you achieve reliable vibration suppression across a wide frequency band. We can provide test samples, technical data sheet and bulk quotation. Contact us to get matched size recommendation and packing solution for your particle damper project.
