RBR series V type sealing ring is a special sealing ring of rolling mill, can replace VA. The seal is made from a special high wear-resisting rubber, can work at 30° C to 100° C, lip line speeds of up to 17 meters per second. It can prevent water, dust, powder, iron oxide and other external impurities into the bearing, can effectively improve the service life of the bearing. When installed, must be in the sealing ring lip grease sealing ring, prevent dry friction, premature damage.
1- application
Mainly used in rolling mill and heavy machinery in the transmission part of the tensile spring to increase the sealing lip of the radial force of the rotating shaft. Application and sealing media can provide sufficient lubrication occasions, the use of temperature in 100 degrees, the use of Ding Jing rubber and Ding Jing clip cloth, the use of temperature above 180 degrees can be used for the use of fluorine rubber and fluorine rubber clip cloth.
2- characteristics and advantages
Good anti abrasion; high temperature resistance, good low-temperature characteristics; ozone resistance corrosion resistance and good climate adaptability; high wear resistance; low friction characteristics; permanent compression deformation; good elasticity.
3- working conditions:
Speed: 0.5m/s
Temperature: -30 degrees C to +150 degrees
Pressure: 40MPa
Medium: depending on the material
