Unitized Metal Face Seals for PTO Shafts - SAP Parts
A very common combination of Cassette Seal & Multi Lip Seal is employed in the Power Transmission Output (PTO) Shaft assembly to protect the mud entry in the gearbox, however this sealing systems does not fully satisfy the intended purpose due its limitations in handling extreme working conditions in and around the PTO system. Also use of multi lip seal is restricted by the temperature limitations of the sealing element material. These seals have sensitivity to radial shaft motion and shaft-to-housing eccentricity. These cannot be ideally used in highly abrasive applications and do not work well with light hydrocarbons, fertilizers, organic residues in in the paddy mud environment. On account of extreme application conditions, in PTO systems conventional sealing arrangements observed to be failing with higher frequency and increased service demands. Now SAP Parts™ proposed a new type of unitized arrangement of metal face seals , with flexible fixing system which allows it t...
