rotary seal design

PSI's metal-encased Duron rotary lip seals replace conventional elastomer oil seals when system pressure exceeds their capability.

The most important factors to consider in designing rotary seal glands are application temperature limits, frictional heat buildup, o-ring stretch, squeeze and 

Here at Simply Bearings we offer a choice of rotary shaft seals suitable for many different uses in the automotive sector, agriculture and industry. Our V ring seals are available in both Nitrile and Viton rubber. V rings are located on the shaft and rotate with it, keeping lubricants in while ensuring grit, dirt and moisture are kept out.

High wearing resistance of the sealing lip. •. Low friction and breakaway forces. •. High flexibility in the lip design. APPLICATIONS. •. Screw compressors.

High pressure rotary shaft seals are designed to keep product in and contamination out. They do so by creating a seal around the rotating shaft found in a

An oil seal normally consists of three basic components: the rubber sealing element, the metal insert (case) and the garter spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal insert will give rigidity and strength to the seal while it is being held in the bore or recessed groove.

Rotary shaft seals work by squeezing and maintaining the lubricant in a thin layer between the lip and shaft. Sealing is further aided by the hydrodynamic action caused by the rotating shaft,

Every custom rotary shaft seal manufactured at AFT Fluorotec is designed and made specifically to suit the application.

Radial shaft seals sit between rotating and stationary components, or two components Robust design; Compliant with national and international standards
