HRO Rod Seals
Model - HRO
Product Description
The HRO Rod Seal has two parts. It is designed as a two-way seal for the rod. It is a PTFE seal and an O ring combined together. PTFE is a very low-friction material, and combining it with the O Ring can be used for a wide range of operations. The HRO Rod Seal works great for the high-speed sliding of hydraulic cylinders.

Material
O Ring – NBR, FKM
Friction Ring – PTFE

Product Description The UIP2 Rod Seal is a one-way, U-shaped rod seal with an asymmetrical design that not only has the shortened lip on its inner diameter similar to the UIP, but also comes with an additional sealing lip on its outer diameter. The second sealing lip provides additional protection, keeping dust and other contaminants from entering the front sealing lip. This helps to protect the mechanism, and prolongs the service life of the cylinder. The UIP2 Rod Seal is mostly used in construction and earth-moving machinery. Material Polyurethane Product Advantages According to ISO 5597 Good media resistance Excellent wear resistance Wide operating temperature range Very good static and dynamic tightness Secondary sealing lip provides additional protection against the ingress of dirt particles Application Earth-moving machinery, construction machinery, agricultural equipment, injection molding machines, fork-lifts, loading platforms and standard cylinders.

Product Description The UNP2 Rod Seal is a one-way, U-shaped rod seal has two symmetrical sealing lips. They are designed to fit the small grooves within hydraulic cylinders of limited space. The second sealing lip provides additional protection, keeping dust and other contaminants from entering the front sealing lip. This helps to protect the mechanism, and prolongs the service life of the cylinder. The UNP2 Rod Seal performs well in lower pressure settings. This kind of seal is perfect for fork-lifts, injection molding machines, agricultural equipment, and so on. Material Polyurethane Product Advantages According to ISO 5597 Good media resistance Excellent wear resistance Wide operating temperature range Very good static and dynamic tightness Secondary sealing lip provides additional protection against the ingress of dirt particles Fit small grooves heights Good sealing performance even at lower pressures Application Construction machinery, agricultural equipment, injection molding machines, fork-lifts, loading platforms and standard cylinders.

Product Description The UIB3 Rod Seal is a seal that has two parts. There is a primary and secondary ring. The secondary ring provides additional cushioning and back-up support due to the pressures from the pistons. The primary ring is a PU seal and the secondary back-up ring is nylon. The inner diameter lip (of the primary ring) is designed with small gaps that reduce the back pressure, and prevent pressure accumulation inside the seal. This design protects the seal so that it can continue to protect the cylinder. The UIB3 Rod Seal set is always used in a sealing system in combination with U-shaped rod seal (e.g. UIP). Material Polyurethane Product Advantages According to ISO 5597 Good media resistance Excellent wear resistance Very good static and dynamic tightness Prevent pressure accumulation between primary and secondary seal Protection against extrusion through secondary sealing ring Application Earth-moving machinery, construction machinery, agricultural equipment, injection molding machines, fork-lifts, loading platforms and standard cylinders.
