Ceetak offer a wide range of seals for use in rotary applications; these range from traditional single or double lipped elastomeric configurations to PTFE based designs – or a combination of both.
Rotary shaft seals work by squeezing and maintaining the lubricant in a thin layer between the lip and the shaft. Sealing is aided by the hydrodynamic action caused by the rotating shaft which creates a slight pump action.
The amount of frictional heat that is generated in an application is dependent on a combination of many operating parameters; shaft surface, internal pressure, operating speed, lubricant type, lubricant levels, lip geometries and lip materials are just a few conditions that should be considered, and it is important to note that these conditions are interactive.
It’s imperative to have an understanding of rotating shaft seals when selecting the correct solution for each application in order to reduce the meantime between failure of rotating equipment.
Our rotary shaft seals are available in many different materials. Rotary shaft seals with elastomeric based lips include Nitrile (NBR), Fluorocarbon (FKM), Carboxylated Nitrile (XNBR), Hydrogenated Nitrile (HNBR), Ethylene Propylene (EPDM), Polyacrylate (ACM), Silicone (VMQ) and Neoprene (CR).
There are various different casings available for rotary seals; most common include carbon steel and stainless steel. Depending on application criteria, other case materials include aluminium, zinc-plated cold rolled steel and Hastelloy®. Springs in stainless steel can also be provided.
