Rotary shaft PTFE radial lip seal
CHO Sealing Tech
PTFE Rotary Shaft Seals appeared first in the 1970's, to resolve automotive crankshaft seal problems that even fluoroelastomers could not solve. Since then PTFE seals have become the standard seal of choice for many applications due to its range of benefits over elastomeric seals as machinery runs faster and hotter with extended maintenance and warranty periods. Some of the benefits of PTFE are higher speed capability, lower coefficient of friction, low wear, both high and low extreme temperature capability and its inertness to most chemicals.
C HO Sealing Technologies have been designing and manufacturing PTFE Rotary shaft seals for over 20 years, for applications ranging from large diesel engines to Racing Cars, and serve both OEM and aftermarket requirements. As can be seen in our "PTFE Brochure", there are many factors to consider when designing and manufacturing a PTFE seal for a specific application. Not least is the fact that PTFE seals are generally used for HIGH duty applications, and therefore require the design and manufacture to be of the highest calibre.
We design, manufacture and test within the highest automotive quality standard, ISO-TS16949. In addition, CHO is the only company of being able to design &am&p; manufacture all three construction types of PTFE seals, as shown in the brochure. This ensures that we offer the most cost effective solution, no matter what the application and quantities.
