Product Overview
This premium repair seal kit is specially developed for Nabtesco GM30H low-speed high-torque hydraulic swing motors, which are widely equipped on construction machinery. The kit integrates a full set of sealing components for complete motor disassembly, overhaul and routine maintenance.
Adopting imported high-performance NBR nitrile rubber and FKM fluororubber as core raw materials, together with reinforced backup rings, the seal assembly delivers excellent oil resistance, pressure resistance, wear resistance and thermal aging resistance. It serves as a perfect direct replacement for original Nabtesco sealing parts. The kit effectively resolves typical failures including external oil leakage, internal seepage and hydraulic pressure loss, and extends the overall service life of GM30H motors under long-duration heavy-load, continuous vibration and harsh outdoor operating conditions.
