Modern design of open grooves We have evolved this highly advantageous system for rod sealing and guiding in consultation with our clients (drawing N°. 3). This design is used for many years in systemup to 25MPa. This proven variation of the open groove offers the following advantage over the conventional design with closed groo- ve: Simple and cost effectivemanufacture of connecting piece head Optimal control of surface areas at the static sealing site and component accuracy to size Safe and fast assembly of sealing and guiding elements without the danger of damage to sealing edges Automatic assembly possible Variable design of guide lengths Service friendly: some components of the sealing system can be quickly and easily replaced Optimal protection against split extrusion of rod sealing through additional support ring. . General assembly information: To avoid assembly related damage and to enhance the service life of seals, please follow the advice given below: To avoid assembly related damage, carefully remove sharp edges, burr and all likely sources of contamination. Adequate lead-in bevels simplify the assembly process and reduce possibility of damage. The following formula gi- ves required lead-in bevel: D- d L= 4 L: Length of lead-in bevel D: nominal external diameter d: nominal internal diameter 13 General Technical Information 3) Axially accessible mounting area (modern design) Locking ring Rod Sealing Guide ring Back-up ring
