Description

 DF(HD) seals are widely used in steel mills and are key components of oil film bearings. Their functions are as follows:
A. Prevent the lubricating oil in the bearing seat from leaking, forming a continuous oil film;
B, Prevent external cooling water, rolling oil, iron chips, dust and other debris into the bearing cavity, to ensure the normal operation of the bearing.
The sealing principle of DF(HD):
The DF(HD)seal rotates synchronously with the cone sleeve, aluminum ring and roll, and produces high-speed relative motion with the sealing baffle, and has five sealing limbs(lips), which have different functions and roles, and cooperate to form an effective seal. The sealing mechanism is the oil film principle of negative pressure, reflux and dynamic pressure.
