Simrit fl oating seals are noted for their reliable seal endurance characteristics. In laboratory tests simulating actual fi eld service conditions (i.e., muddy water) at 1 m/s for over 1000 hours, track roller assemblies showed no leakage and essentially no seat wear using standard 80W-90 gear oil as the lubricant. There was also no noticeable deformation or deterioration of elasticity in the fl oating seal O-rings.Simrit fl oating seals are designed to operate under the following conditions: > Lubricant pressure within seal cavity of 1.5 kg/cm > 2 (maximum 2 kg/cm > 2 ) Circumferential speed...

The effectiveness of fl oating seals is dependent on the combination of tough materials used in a unique confi gura-tion of the fl oating seal and the O-ring. As the worlds leading elastomer developer, Simrit can provide the best material to match the requirements of each application. Hydrogenated Nitrile (HNBR) Description: HNBR is obtained by partially or fully hydrogenating NBR, leading to considerable improve- ment of the resistance to heat, ozone, and aging. Temperature Range: Җ40C to 120аC Floating seals consist of two basic components, the metal seat and the elastomer. Standard Fluoroelastomers...

Long-term endurance testing on Simrit fl oating seals demonstrates that properly installed seals in track roller applications provide over 3000 hours of maintenance-free performance without the need for oil replenishment. Correct installation of the seal is critical to long service life. If at any time the assembly housing or fl oating seal is disassembled, a new seal should be installed before reassembly and use of equipment. Failure to do so may result in oil leakage and a shortened seal life. Step Two: Install the fl oating seal with the properly fi tted O-ring in the housing (Diagram 2)....

The ES100 fl oating seal was developed as a seal for the track rollers used in construction machinery and vehicles. It is simple in construction, consisting of O-rings and fl oating seats made of special cast iron. Its performance is dependent on the sealing capabilities and elastic distortion of the O-rings, as the fl oating seats are supported by the O-rings. The seal effectively excludes sand, dirt, and water and is widely used in bulldozer and excavator under-carriage applications. The ES100 is generally the most common and most cost-effective solution, but requires precise machining of the...

A sister product of the type ES100 seal, the ES764 allows for a simpler housing design and construction. The housing is easier to machine (see page 9), but more housing space is required and fewer tooled sizes are available. This economy of design provides reduced manufacturing costs in agricultural equipment and other fi eld machinery. The ES764 has a higher pressure capability and range compared to the type ES100 seal. The type ES764 seal utilizes a unique wing-form elastomeric packing with fl oating seats made of special alloy cast iron. Type ES764 Seal Cross Section > The seal seat is a special...
