1. Dimensional accuracy
Dimensional stability: The diameter of chrome steel balls is very precise and is usually manufactured by high-precision machine processing or grinding. Their standard sizes can reach micron levels with extremely small tolerances.
Smooth surface: The surface of chrome steel balls is finely polished and ground, with a high surface finish, which reduces the effects of friction and wear.
2. Shape and density
Spherical shape: The spherical shape of chrome steel balls ensures that they can maintain uniform force distribution when rolling, reducing friction and vibration.
High density: Chrome steel balls have a high density, usually between 7.5-8.0 g/cm³, which gives them good inertia and stability when running at high speeds.
3. Application range
Bearings: The most widely used application of chrome steel balls is in rolling bearings, where they are used to support rotating parts and reduce friction.
Sliding systems: Chrome steel balls are also used in mechanical equipment such as linear slide systems and guide rails.
Other mechanical equipment: In addition to bearings, chrome steel balls are also used in many fields such as automobiles, aerospace, machining, and conveying equipment.
4. Weight and power transmission
Stability and inertia: Due to the high density and weight of chrome steel balls, they can maintain good stability during movement and reduce vibration and imbalance.
5. Noise control
Low noise: The uniform rolling characteristics of chrome steel balls make them produce less noise during operation, which is very important for high-precision equipment.
6. Durability
Long life: Due to their excellent wear resistance and strength, chrome steel balls can usually work for a long time under high load and high speed environments, reducing maintenance frequency and replacement costs.
7. Customizability
Various materials and specifications: Chrome steel balls can be selected in different sizes according to needs to adapt to different application occasions.
