The zinc alloy 8-shaped oil groove bushing is a specific mechanical component, mainly made of zinc alloy material, with an 8-shaped oil groove designed inside.
 

Material Properties
Zinc Alloy: Zinc alloy is an alloy composed of zinc and other elements, possessing excellent mechanical properties, friction properties, and wear resistance. It is also spark-free and non-magnetic, and can replace more expensive bronze and brass copper alloys in manufacturing bushings and other wear-resistant parts.
 

Structural Features
8-shaped Oil Groove: The 8-shaped oil groove is a special design inside the bushing, mainly used for storing grease and providing lubrication. This design helps reduce friction between the bushing and the shaft, improving equipment operating efficiency and lifespan.
Inner Hole Design: The inner hole of the bushing usually matches the diameter of the shaft to ensure the shaft can rotate smoothly within the bushing. The surface accuracy and smoothness of the inner hole significantly impact the bushing's performance.
 

Manufacturing Process
Casting: Zinc alloy bushings are usually manufactured using casting methods, by melting the zinc alloy and casting it into a mold, obtaining the finished product after cooling.
Machining: After casting, a series of machining operations, such as cutting and grinding, are required to achieve the required dimensions and precision.
Oil Groove Machining: Machining the 8-shaped oil groove is a crucial step in the bushing manufacturing process. It is usually processed using CNC lathes or specialized machines to ensure the shape, size, and position accuracy of the oil groove meet requirements.
 

Application Areas
Zinc alloy 8-shaped oil groove bushings are widely used in various mechanical equipment, such as automobiles, engineering machinery, metallurgical equipment, and chemical equipment. It is mainly used to support and lubricate rotating shafts, reducing friction and wear, and improving equipment operating efficiency and stability.
 

Performance Advantages
Good Wear Resistance: Zinc alloy has good wear resistance and can withstand shaft friction for a long time without easy wear.
Good Lubrication Effect: The 8-shaped oil groove design helps store and distribute grease, improving lubrication, reducing friction and wear.
High Strength: Zinc alloy bushings have high strength and can withstand significant mechanical loads.
Good Corrosion Resistance: Zinc alloy has good resistance to various corrosive media and can maintain stable performance in harsh working environments.
