It can realize horizontal 360-degree rotation and up-and-down 180-degree turnover, and the safety factor in any direction is four times. Compared with the traditional DIN580 eyebolt (dead eyebolt), it is more flexible and can meet all lifting requirements. The domestic production materials are mostly 35CrMo alloy steel and 42CrMo alloy steel, and the imported materials are generally Ni-Cr-Mo alloy steel or 100 grade materials. According to the connection mode with the hoisted object, it can be divided into two types: screw hole type lifting ring and bolt type lifting ring. According to the lifting angle, it can be divided into straight pull ring, side pull ring and straight side pull universal ring.

Supply specifications: Most of the specifications available in the market are concentrated in M8-M64.

According to the degree of tension, it can be generally divided into G80 and G 100 swivel. The tensile strength of G 100 grade products is 25% higher than that of G80 grade products, which is a relatively high-end product on the market at present.

Rotating ring bolt thread: at present, only a few foreign brands can provide both metric and English threads, and most of them are metric in China. Due to the requirement of equipment for English thread processing, only a few domestic manufacturers can produce threads that fully meet the British and American standards.

Strength grades of rotating ring bolts: mainly 8.8 and 12.9. Among them, 12.9 bolts are mostly used for imported swivel, and 8.8 bolts are mostly used for domestic swivel.
