Swing motors are hydraulic motors that form the proper turning force of excavator booms using oil pressure, shift rotation either to the right or left and convey or cut off turning power.

Swing motor seal kits maintain the power of the swing motor.

If the swing motor leaks oil, the boom cylinder will be powerless.

* Seal kits are made of specialized materials for the maximizing durability with wear resistance, properly heat treated body to produce optimum performance of the machine and life time seal and lubrication which were thoroughly checked by standard rule on each seal kit in order to ensure a perfect sealing. Thus, the perfect oil sealed lubrication is assured of life time service operation in terms of retaining the oil lubricant for the perfect operation between piston and cylinder.
