0310908 RING For HITACHI EX100 4BD1

The ring is a key component used in construction machinery, mainly used in cable reels, fire trucks, cranes, excavators and other equipment that requires 360 degrees of rotation. ‌ Its main function is to solve the problem of wire entanglement, by disconnecting the wire and keeping at least one end in contact, so that the wire will not be entangled when the machine is rotating, so as to protect the machine from damage.

The main feature of a ring is its closed circular structure. It usually presents a continuous, unbroken circular outline, and although different types of rings may differ in size and size, their basic circular shape is a common feature. Rings can be made of a variety of different materials, including metal, plastic, wood, etc. During the production process, it is usually necessary to go through cutting, grinding, welding and other processes to ensure the integrity and stability of the ring. For metal rings, additional surface treatments may also be required to increase their corrosion resistance and aesthetics.

Excavator rings can be divided into many types according to different application scenarios and technical requirements. For example, the mining ring chain is a high hardness, wear-resistant ring chain, used for heavy machinery and equipment transmission; Excavator wear ring is a kind of seal, used to improve the wear resistance and service life of the machine; The electric slip ring is specially designed to solve the problem of high-pressure oil transportation, and adopts the design of anti-vibration structure to ensure stable operation under high strength environment.
