Rotary Seal are special seals mainly used for center joint of industrial equipment. Rotary Seal have excellent sealing ability and low friction.There are two main types of rotary seals for rotary joints, composite seals and mechanical seals. The composite material rotary seal is composed of two parts. It consists of an outer ring made of PTFE and an O-ring made of NBR. O-rings support the outer ring, making the entire rotary seal easier to install. Slide between the outer ring and the housing of the swivel joint.

There are two main types of rotary seals for rotary joints, composite seals and mechanical seals. The sealing performance of the composite material seal is relatively better, and it is used in the occasion where the hydraulic cylinder has intermediate positioning. Due to the small size of the seal itself, the rotary joint sealed with composite material can make the rotary joint more compact and compact. The cost of composite seals is also much cheaper than mechanical seals. The composite material rotary seal is composed of two parts. It consists of an outer ring made of PTFE and an O-ring made of NBR. O-rings support the outer ring, making the entire rotary seal easier to install. Slide between the outer ring and the housing of the swivel joint.

The material of the rotary seal is a wear-resistant composite material or a metal material, and the rotary seal is installed between the mandrel and the housing. Rotary seals can withstand high pressures, usually up to 200 bar, with hard materials and poor sealing performance. The oil seal is a skeleton lip seal, which cannot withstand excessive pressure, usually can not exceed 3 bar, but it has a good seal under the condition of low pressure and high speed, and its role is to seal the leakage oil from the rotary seal. The leaked oil must be drained back to the tank under very low pressure to protect the oil seal from damage. Do not install a filter on the leaking oil pipe. The rotary joint is combined with the expansion and contraction cylinder through the rightmost flange, and the oil port of the rotary joint is docked with the oil port of the hydraulic cylinder.
Mechanical seals can theoretically achieve non-contact sliding and can achieve a long life. The production of mechanical seals is more complicated, and the accuracy requirements are relatively high, which is relatively expensive.
