Good sealing performance in extremely small assembly conditions.
• Excellent wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.
• Good energy efficiency due to low friction.
• Insensitive to pressure peaks.
• High temperature resistance assured by suitable O-ring compound selection.
• Improved lubrication due to pressure medium deposit in the dynamic contact area.
• High extrusion resistance.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.
• Short axial assembly length.
• Installation in closed and undercut housings.
• Available in diameters from 4 to3000 mm.• Additional sizes of machined products available on short notice.
Producers of rotary distributors prefer simplified seal designs. This can be achieved by means of profile OR internally sealing rotary sealing sets. The OR sealing set consists of a wear-resistant, low-friction slipper sealing ring and an elastomer O-ring as a preloading element. It is suitable mainly for applications where the pressure alternates from one side of the seal to the other, such as pivots for rotating track rings, swivel joints, hose reels, and in machine tool hydraulics. If the sealing set is used as an end seal, it is recommended to install a wiper ring at the end of the components. Depending on the special working conditions, the rotary sealing set OR is equipped with one or two circumferential lubricating grooves.
3. Installstion
Installation the groove carefully to remove burrs and clean. The inside of the cylinder should be chamfered at the entrance. Type OK seals can be enclosed in closed grooves.
Material Science:
Cylinder sesaling ring: filled with modified thermoplastic material (W5019)
Expansion ring: NBR based rubber with shore hardness of 70 (N3571)
4. Company Information
Chengdu Dingfeng Sealing Material Co., Ltd. was established in 2003. After more than ten years of experience, in 2013, we cooperated with foreign seal companies to develop high-end seals. The product has been repeatedly tested and tested by the excavator factory and the oil tank factory, and after continuous improvement and innovation, it has finally been successfullydeveloped.
Currently cooperating units: Chengdu Huachuan Industry, Chenggong Loader Factory, Chengdu Largest Excavator Factory, etc. Products are exported to Southeast Asia, the United States, Britain, Russia, Saudi Arabia, etc.
The products are strictly controlled from the selection of materials, production, after-sales service, and every detail. The raw materials are all modified TPU particles newly developed by DuPont of the United States, and the wear resistance and temperature resistance can reach the extreme. The purpose is to make domestic quality seal rings.
The product types are: IDU, ODU, DHS, FAK, AY, UN, A1, BS, B3, B7, ZP, HBY, OK, Stefan, Glyy ring and other products. As well as industrial cylinder repair kits, engineering machinery cylinder repair kits, and a complete set of repair kits for roller press cylinders in cement plants. Fully meet customer needs.
