9 Factors in Choosing an Oil Seal
From Oil Seal Manufacturers , we know that the primary causes of external lubricant leakage in pumping systems, hydraulic presses, gearboxes and tanks are incorrect selection, improper application, improper installation and improper maintenance of sealing systems. These problems can be overcome by better understanding the types of seal materials available, redefining the selection process, and consistently applying sound replacement and maintenance practices. There are a number of variables that must be considered when selecting oil seals. When specifying oil seals, designers and maintenance engineers must evaluate nine factors: Shaft Speed The maximum shaft speed allowed is determined by the shaft finish, runout, concentricity of the housing bore and shaft, the type of fluid being sealed, and the type of oil seal material. Temperature The temperature range of the mechanism where the oil seal is to be installed must not exceed the temperature range of the oil seal elastomer.
