Selection of seal design and material

Selecting an appropriate seal design and material depends on the operating conditions of the application such as:
  • temperature
  • speed
  • type of lubricant
  • vertical or horizontal orientation
  • runout and shaft-to-bore misalignment
Because the influence of one operating condition typically dominates the seal selection process, there are no universal rules for determining the appropriate seal type or design for a given application. This section describes how operating conditions affect seal performance and service life and provides guidance on selecting the most appropriate seal for a given application.
The standard SKF radial shaft seals and their main features and permissible operating conditions are listed in the Seal selection table for general industrial applications and in the Seal selection table for heavy industrial applications.
