We make rings of special cast iron for sealing transmission shafts.
"Tehnolit" offer rings with different types of locks - straight, angled, with a labyrinth seal.
At the request of the customer, alloyed high-strength or gray cast irons can be used.
To increase the wear resistance, we apply the method of ion-plasma hardening. This method allows to strengthen the working surface of the rings from high-strength cast iron to 800 HV from gray cast iron to 550HV to a depth of 0.4 mm. For the ring run-in, we use tin plating.
We offer sleeves made of special cast iron to work in pairs with our rings.
