1. Material

Rings

The inner and outer rings of the 672ZZ bearing are fabricated from high - grade chrome steel. Chrome steel boasts exceptional hardness, which enables the rings to endure the intense pressure and friction generated during the bearing's rotation. Additionally, it offers good wear resistance, ensuring that the rings maintain their shape and functionality over an extended period of use. This material choice also contributes to the bearing's overall structural stability.

Balls

The rolling balls within the 672ZZ bearing are made of chrome steel as well. These balls undergo precise machining to achieve a perfect spherical shape and a smooth surface finish. The use of chrome steel for the balls ensures that they have excellent hardness and toughness, allowing them to withstand the loads and stresses encountered during operation. The consistency in material between the balls and rings also helps in maintaining uniform performance and reducing wear.

Cage

The cage of the 672ZZ bearing is typically constructed from low - carbon steel. Low - carbon steel is chosen for its good formability and ductility, which makes it easy to manufacture into the required cage shape. It provides sufficient strength to hold the balls in place and maintain their proper spacing, ensuring smooth rotation. Moreover, low - carbon steel is cost - effective, which helps in keeping the overall production cost of the bearing manageable.

Shields

The two shields on the 672ZZ bearing are made of cold - rolled steel. Cold - rolled steel has a smooth surface and good dimensional accuracy, which allows the shields to fit tightly against the rings, effectively preventing the ingress of dust, dirt, and other contaminants. This protection is crucial for maintaining the bearing's internal cleanliness and ensuring its long - term reliable operation. The cold - rolled steel also offers adequate strength to withstand the external environment.

2. Applications

Precision Tools

In precision tools such as small - sized drilling machines and miniature grinders, the 672ZZ bearing is commonly used. Its ability to provide smooth rotation and withstand moderate loads makes it suitable for these tools, which require precise movement. For example, in a small - scale engraving machine, the bearing ensures that the spindle rotates steadily, contributing to the accuracy of the engraving work.

Office Equipment

Office equipment like small - sized scanners and shredders often incorporate the 672ZZ bearing. In scanners, it is used in the roller mechanisms that move the documents, ensuring smooth and consistent feeding. In shredders, it helps in the rotation of the cutting blades, allowing for efficient shredding of paper and other materials. The bearing's compact size fits well within the limited space of these office devices.

Household Gadgets

The 672ZZ bearing can be found in various household gadgets. For instance, in small electric mixers, it is used in the motor's rotating parts, ensuring smooth operation and reducing noise. In mini vacuum cleaners, it helps in the rotation of the brush rollers, enhancing the cleaning efficiency. Its reliable performance and affordability make it a preferred choice for these household applications.
