    Cautions


     

    · Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.

     

    · Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.

     

     

    · Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures

     

    · The bit should be kept indoor with dry and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.

    ROLLER BEARING

     

    Based on the calculating of the load distribution on the bearing components,all shareate bits incorporate bearings that have optimal geometry and load distribution designed to give maximum bearing life.

     

    1. Non-Sealed Bearings

    Bearing Type:Roller-Ball-Roller-Thrust Button without seal.

     

    2. Sealed Bearings

     

    Bearing Type:O-Ring Seal-Roller-Ball-Roller-Thrust Button. See

     

    ·The seal keeps the mud,cuttings,air and water ouside the bearings.

    ·The bearing works in lubricant and friction conditions,this results in less bearing wear and longer bearing life.
