How to Choose the Right Seal Kit?

1.Verify the Motor Nameplate: Knowing the excavator model is helpful, but checking the specific metal nameplate on the swing motor (e.g., Kawasaki M5X130) is the most accurate way to ensure fitment.

2.Identify the Leak Location:

If oil is leaking from the base, focus on the Shaft Seal (Skeleton Oil Seal).

If the swing movement is weak or drifting, focus on the Internal Piston Seals.

3.Material Quality: We recommend choosing seal kits made of NOK or SKF materials, which offer superior performance in high-temperature and high-pressure environments.

Why Choose Our Seal Kits?

Premium Quality: Made with imported sealing materials, our kits offer a 50% longer service life than standard aftermarket parts.

Ready to Ship: We stock kits for 90% of global excavator brands, ensuring immediate dispatch.

Precision Fit: 1:1 mold development ensures easy installation and zero-leak performance.
