Hydraulic sealing products — Size charts This document should be used in conjunction with the latest version of our Hydraulic Sealing Guide In the following pages we present our size charts for our most popular hydraulic sealing products • Chevron® (Shallex®) — rod/gland & piston seals • Lionsele® LF — rod/gland & piston seals43 Face Type Seals Design Chart 43 explains how to design an Oring seal when the groove is cut into a fl at surface Note that when the pressure is outward, the groove outside diameter (OD) is primary and the, groove width then determines the inside diameter Conversely, when the pressure is inward, the groove inside diameter is primaryORing Standard Size Charts ORings are available in various standard sizes Refer to our oring sizing charts for the most commonly used sizes around the world like;
V-ring seal size chart pdf
V-ring seal size chart pdf-Felt seals are simple seals which allow a circumferential speed of 4m/s Before fitting felt seal s they should be soaked in warm oil for several minutes Sho uld temperatures be in excess of 100 °C the felt seal shoul d be replaced with a temperature resistant seal The double lip seal is split and allows a circumferential spee d of 8m/sPassing the top rings to quickly escape to the crankcase If the second ring gaps are set smaller than the top ring gaps, the engine may show less leak down under static conditions!
To find the groove dimensions on a rotating seal, use Design Chart 5 Find the shaft size in the second column The groove root diameter and width will be found under their respective columns The Pressure Seals Oring size will be found in the first column next to the shaft diameter BACKUP RINGS (Design Chart 7)Temperature range 30° F to 325° F / 34° C to 163° C)Tetrafluoroethylene propylene (Aflas®) — More expensive than fluoroelastomers, this material has better chemical resistance to all hydrocarbon fluids, acids, bases, and oxidizing agents It can perform in the complete range of hydraulic fluids and has continuous heat resistanceBearing Isolator, VRings and Heavy Duty DF ® (HDDF) seals Size listings for each style and type of seal or sleeve, material and compound selection guide, compound compatibility chart, and recommended operating conditions charts complement the product data Installation instructions and troubleshooting guidelines are also provided
An Oring seal is used to prevent the loss of a fl uid or gas The seal assembly consists of an elastomer Oring and a gland An Oring is a circular crosssection ring molded from rubber (Figure 11) The gland — usually cut into metal or another rigid material — contains and supports the Oring (Figures 12Seal Types & Gland Design *Note The current revision of the Standard is "C" but it changes periodically **ORing seal sizes not listed are not recommended for axial seals because the seal ID after installation becomes too small for practical use wwwapplerubbercom (US & Canada Only) • (International)Cartridge mounted, hydraulically balanced single and dual seals available in Oring pusher and metal bellow nonpusher designs The Oring pusher design features Alloy C276 springs that are isolated outside of the product and located in the nonrotating component of the seal The nonpusher metal bellow design features Alloy C276
