Product Details

Product name: Bearing Steel Grit

Model/Size: G12-G150 Φ0.1mm-2.8mm

Product Detail:

Bearing steel grit, also known as enhanced environmentally-friendly grit, is crafted from bearing plates. This unique material incorporates rare elements such as chromium (Cr), molybdenum (Mo), and manganese (Mn), which contribute to its exceptional internal structural stability.

Distinguished by its high stability and wear resistance, bearing steel grit outperforms traditional high-carbon steel grit in terms of durability. In fact, its’ service life is approximately 2.5 times longer, making it a cost-effective and efficient choice for various industrial applications.

Advantages and Applications


  Bearing steel grit boasts material stability and an exceptional composition that includes the rare elements chromium (Cr), molybdenum (Mo), and manganese (Mn). Its high hardness makes it ideally suited for demanding applications such as shipbuilding and pipeline construction, where it excels in processing large workpieces.

  Production process of bearing steel grit is distinct, ensuring that the composition and characteristics of the raw materials remain unchanged throughout the manufacturing process. This ensures consistent quality and performance.

  Specially designed for granite cutting, bearing angular steel grit delivers faster cutting efficiency and smoother cutting surfaces. Its sharp edges, uniform sizes, and excellent wear resistance contribute to these outstanding results, satisfying customer needs.

④  Bearing steel grit is renowned for its durability, producing minimal dust during use. This not only enhances the working environment of sandblasting workshops but also reduces the load on dust collectors, promoting environmental protection and worker health.

  Crafted from bearing off-cut steel in its forging state (as opposed to casting), this new steel grit undergoes a professional process involving quenching, crushing, sieving, and special heat treatments. The resulting angular shape combines abrasive resistance with impact ductility. In use, the angular shape gradually transitions to an arc shape, making it ideal for oxygenated surface descaling, cleaning, and peening. This significantly improves blasting efficiency, coating quality, and reduces paint kinetic energy, abrasive consumption, and wear on parts, thereby extending their lifespan.
