Product Overview
This premium repair seal kit is professionally engineered for Nabtesco GM09 low-speed high-torque hydraulic travel motors, widely adopted as final drive motors for mini and medium-sized excavators. It covers mainstream displacement models of the GM09 series and contains a complete set of sealing components for full motor disassembly, overhaul and routine maintenance.
The sealing assembly adopts high-quality imported NBR nitrile rubber and FKM fluororubber as core materials, paired with reinforced backup rings. It delivers excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. As a fully compatible direct replacement for original Nabtesco sealing parts, this kit effectively resolves typical malfunctions such as external oil leakage, internal leakage and hydraulic pressure drop. It greatly extends the service life of GM09 travel motors operating under long-term heavy load, continuous vibration and harsh outdoor working conditions.
