Disc opener bearing

          
            The opener is the core working component of the planter. The working      
          principle of the double disc opener is two grooved discs, which are
          inclined to each other and intersect at one point. Working under the
          action of soil reaction, the grooved disk is supported by the opener
          bearing. With the continuous improvement of agricultural production
          efficiency, more and more farmers are using high-speed planters, and
          the speed of sowing is getting faster and faster. Due to the smaller
          diameter of the grooved disc, the relative rotational speed of the
          bearings of the planter is higher. Bearing failure and shaking will
          directly affect the effect of seed metering, and seeder bearings are
          generally closer to the ground, and are more susceptible to debris and
          weeds, so the reliability of the opener bearing is particularly important. 


              

     
     
The stable bearing capacity

       Because the working state of the opener disc is tilted, the bearing
      is not only subjected to the soil force, but also bear the lateral
      overturning force, coupled with the impact force from time to time,
      the ordinary angular contact bearing will produce a shake under the
      combined force, the shake will be amplified at the end of the disc.
      CSELITE opener bearings have a four-point contact structure,
      which means that the bearings can withstand biaxial axial load, even
      in the event of unexpected impact can remain stable.

 

      
         
Low torque sealing system
        The opener disc cuts the soil using two rotating flat discs and pushes  
          the soil to the sides to form a seed furrow. If the torque of the sealing
          system itself is too large, it will affect the normal rotation of the
          opener disc. The wear form of the disc will change from rolling
          friction to sliding friction, and the disc will wear rapidly; if the
          torque of the sealing system itself is too small, This will result in a
          more susceptible failure of the sealing system, so the reasonable
          dynamic torque of the sealing system is important. Thanks to
          CSELITE's long-term study of the dynamic torque of the sealing
          system, the R-type seal used in opener bearings can ensure excellent
          sealing effect at lower torque.







              


     More choices
      CSELITE provides separate trenching bearings, and different forms
     of bearings can meet different openers.
     All series bearings are assembled with low torque R seals to ensure
     stable operation of bearings.



                                   

        
             
Corrosion resistant surface

            Modern planters carry out both seeding and fertilization, including      
         granular fertilizers and liquid fertilizers, but the corrosiveness of
         fertilizers is often easy to corrode the surface of bearings, leading
         to bearing failure. CSELITE opener bearings have a special
         electroplated surface which can effectively prevent corrosion and
         ensure long-term stable operation of the bearings. Even after the
         opener disc is worn and replaced, the surface of the bearing assembly
         remains in a new state.
