Core Advantages
Superior Wear Resistance:
Made from GCr15 bearing steel with HRC 58-62 hardness, the wear loss is only 1/3 of ordinary steel grit. Under the same working conditions, the service life is extended by 120%-180%, reducing the frequency of abrasive replacement.
01
High Grinding Efficiency:
The angular particle shape ensures strong cutting force. Compared with traditional abrasive materials, it can increase the surface treatment speed by 30%-40%. For example, it takes only 45 minutes to grind 100pcs of bearing rings, while ordinary steel sand takes 70 minutes.
02
Significant Cost Savings:
Integrating long service life and high efficiency, the comprehensive cost per unit area of surface treatment is reduced by 25%-35%. For a medium-sized auto parts factory, it can save more than $80,000 in abrasive costs annually.
03
Stable Supply Capacity:
With 3 production bases and a monthly output of 5,000 tons, the regular inventory is maintained at 1,000 tons. It can meet the urgent order demand of 500 tons within 72 hours, avoiding production interruption caused by abrasive shortage.
04
Uniform Particle Size:
The particle size distribution deviation is ≤5%, which ensures consistent surface roughness of the processed workpieces. The pass rate of workpiece surface quality is increased by 15%-20% compared with using irregularly sized abrasives.
05
Application Scenarios
Bearing Manufacturing Industry
Used for deburring, rust removal and surface strengthening of bearing inner rings, outer rings and rolling elements. It can effectively improve the surface hardness of bearings by 5%-8% and extend the fatigue life of bearings by 20%-30%. Applicable to deep groove ball bearings, tapered roller bearings and cylindrical roller bearings.
Automobile Parts Industry
Suitable for surface treatment of engine crankshafts, gears, brake discs and other key parts. It can remove the oxide scale formed during forging and casting, and obtain a uniform matte surface, which is conducive to subsequent painting and coating. The processing efficiency of auto gears is increased by 35%, and the coating adhesion is increased by 10%.
Construction Machinery Industry
Applied to rust removal and anti-corrosion treatment of excavator bucket teeth, bulldozer blades and other wear-resistant parts. The abrasive can penetrate into the small gaps of the workpiece surface, achieving thorough rust removal. The anti-corrosion service life of the treated parts is extended by 1-2 years in harsh working environments.
Steel Structure Industry
Used for derusting and descaling of steel plates, section steels and steel pipes before welding and coating. It meets the Sa2.5 level derusting standard specified in ISO 8501-1, and the surface roughness can be controlled between Ra 40-80μm, ensuring the welding quality and coating effect.
Hardware Tools Industry
For surface polishing and edge rounding of wrenches, pliers, hammers and other hardware tools. It can remove the burrs generated during machining without damaging the workpiece structure, improving the hand feel and appearance quality of the tools. The product qualification rate is increased by 18%.

Customer Cases
Case 1: A Leading Bearing Manufacturer in Zhejiang
The customer used ordinary steel sand before, with frequent replacement and high cost. After switching to our bearing steel sand, the replacement cycle of abrasive was extended from 3 days to 8 days, the processing efficiency of bearing rings was increased by 32%, and the annual abrasive cost was reduced by about $95,000. The surface roughness of the processed bearings is stable at Ra 50-60μm, and the product qualification rate is increased from 88% to 99%
Case 2: An Auto Parts Supplier in Guangdong
The customer mainly processes engine gears, requiring high surface quality of the gears. Our bearing steel sand effectively solves the problems of uneven rust removal and inconsistent surface finish of the original abrasive. The gear processing cycle is shortened by 28%, the coating adhesion test reaches the highest level of 5B, and the customer's product competitiveness in the market is significantly improved.

Uses of bearing sand
Bearing sand is an important material specially used in the manufacturing and processing of bearings. It plays a vital role in the production process of bearings. The following are some of the main uses of bearing sand:
1. Polishing in the processing of bearing steel balls
Bearing sand is widely used in polishing equipment in the processing of bearing steel balls. For example, there is a polishing equipment for the processing of bearing steel balls, which includes the use of bearing sand. This equipment can facilitate the separation of polished bearing steel balls and grinding sand during the polishing process of bearing steel balls by setting a separation box and a screen. In addition, by setting a discharge port, a receiving box and a sand discharge plug, the separated bearing steel balls and grinding sand can be collected, avoiding the problem of the separated bearing steel balls and grinding sand being scattered everywhere, thereby bringing convenience to the use of the polishing equipment.
2. Metal surface treatment
Bearing sand is also widely used in metal surface treatment, including cleaning the oxide scale on the metal surface, castings, etc. Bearing sand of different hardness levels is suitable for different metal surface treatment needs. For example, bearing sand with a hardness of 40-50HRC is suitable for cleaning the oxide scale on the metal surface, such as castings.
3. Sandblasting operation
Bearing sand is also used in sandblasting operations, which is a common surface treatment technology that cleans or prepares metal surfaces by spraying abrasives (such as bearing sand) at high speed. This technology can remove impurities, oxide layers and other unwanted attachments on the metal surface, thereby improving the quality of the metal surface and the efficiency of subsequent processing.
