Seal

We wonepart YD seal system offers a wide selection of rod seals to provide customers with the best solution to prevent the intrusion of external media into the system. Our products can meet the requirements of users with low friction, compact structure and easy installation. We have NOK Japan, Corteco, CFW, SKF, Hallite, NDK, TTO, CHO and so on. NOK Types as IDI,ISI,IUH,IUIS,UNI,SPNO,SPN,SPNS,SPNC.

Piston seals maintain sealing contact in sliding motion between the piston and cylinder bore for hydraulic and pneumatic equipment.
The piston seal is a shaft seal, and the piston rod seal is a hole seal. The oil cylinder is composed of a cylinder block, a piston, a piston rod, a cylinder head and a sealing ring. When using a piston seal, it can be used in combination with an anti-pollution seal to prevent damage due to foreign matter or adiabatic compression, which can improve durability. Types as following: ODI,OSI,OUIS,OUHR,OKH,SPGO,SPG,SPGM,SPGN,SPGW,SPGC,CPI,CPH

Dust seal is a rubber material sealing ring used for vehicles, machinery and engineering machinery to prevent dust and dirt from entering.The dust seal is generally used in conjunction with a rubber round rubber ring. It is used in some mechanical equipment and hydraulic piston systems to be installed at the connection part of the machine to prevent outside dust and dirt from entering the equipment, especially in harsh environments.
NOK standard, dust /wiper seals including DKI,DWI,DWR,DKBI,DKBI3,DKBZ,DKB,DKH,DSI,LBI,LBH,BUHK,DSPB

Wear ring or guide ring is used as bearing of rod and piston to prevent its scoring or accentricity and to improve the durability of the packing.For high speed, low load, or creeping, please use polytetrafluoroethylene resin model RYT or RYT2 with excellent friction and abrasion characteristics.The material of RYT is polytetrafluoroethylene resin, which is characterized by a low friction and wear ring without creeping. We calculate by volume and can cut according to the size of the cylinder bore. Can withstand temperatures ranging from -55 degrees Celsius to 220 degrees Celsius.

Floating Seal also known as duo cone seal or mechanical face seal, floating seal is an essential sealing part for final drives and wheel assemblies of excavators, bulldozers and other construction machinery. It consists of high-hardness alloy cast iron seal rings and elastomer O-rings in NBR, HNBR or FKM, available in DO and DF types. With precision lapped sealing surface, it features outstanding wear resistance, temperature resistance and anti-fouling performance.
Adopting advanced floating compensation design, our products automatically offset shaft eccentricity and runout. The uniform oil film formed during operation delivers excellent self-cleaning effect and maintenance-free service. It works steadily at -40℃ to 200℃ with max working pressure up to 3MPa, and the service life exceeds 8000 hours under standard conditions.
As a core product of WONEPART, our floating seals and full-range machinery parts have been widely used in major projects including Lusail Stadium for Qatar World Cup, performing reliably under high temperature and sandy conditions. We offer 18-month warranty and global after-sales service, providing trustworthy sealing solutions for heavy-duty equipment worldwide.

Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. They also compensate for large temperature fluctuations. Back up ring including BRT, N4W. Hydraulic cylinder seals prevent the leakage of working medium (internal and external leakage) and prevent foreign objects (such as air, dust and water) from entering the hydraulic components and hydraulic system.

Buffer seal is used in combination with rod packing to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing. The cylinder is cushioned and sealed, and the product itself has a pressure relief groove for easy exhaust. Robust design.
Material: PU+Nylon; PTFE+Rubber+Nylon; PU;
We have Original NOK Japan brand and other OEM brand.

O-ring is a rubber seal with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring and is also called an O-ring. It first appeared in the mid-19th century, when it was used as a sealing element for steam engine cylinders.
O-ring specifications include UHSO-ring specifications, UHPO-ring specifications, UNO-ring specifications, DHO-ring specifications, piston rod O-ring specifications, high temperature O-ring resistance, high-pressure O-ring resistance, and corrosion-resistant O-ring Ring, wear-resistant O-ring. FKM and NBR with NOK brand and OEM brand.

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.
