Product Description

Product Description

Description

 MT is a further technical development of MT Ring. It is fully interchangeable with earlier MT seals in all new applications. The main benefits of the patented seal are provided by the innovative functional principle of the trapezoidal profile cross section. The sides of the seal profile tapers towards the seal surface. The profile can thus retain the robust and compact form typical of piston seals without losing any of the flexibility required to achieve a pressure-related maximum compression.The edge angle of MT permits an additional degree of freedom and enables a slight tilting movement of the seal. The maximum compression is thus always shifted towards the area of the seal edge directly exposed to the pressure. On the low-pressure edge of the seal, MT Ring exhibits only zones with neutral strains without compressive or shearing loads, thus effectively reducing the danger of gap extrusion. 
The resulting benefits are as follows below.
 
 
 ADVANTAGES
 
 --Very good static sealing performance
 --Increased clearance possible (approximately +50%), 
--depending on the operating conditions
 --Low friction, no stick-slip effect
 --Simple groove design
 --Fits standard Stepseal groove dimensions as well as  
ISO 7425-2 seal housing
 --Adaptable to the operating conditions due to a wide range of 
materials 
 --Suitable for environmentally friendly hydraulic fluids
 --Available for all rod diameters up to 2,600 mm
 
 
APPLICATION EXAMPLES

--Injection molding machines
 --Machine tools
 --Presses
 --Handling machinery
 --Servo equipment
 --Agriculture
 --Valves.
