Product Overview
This premium repair seal kit is specially engineered for Nabtesco GM38 series hydraulic final drive travel motors, a widely adopted low-speed high-torque motor for medium and large excavators. It fits mainstream sub-models including GM38VB, GM38VC and GM38VC-A, fully covering the standard displacement range of the GM38 series.
The kit is assembled with complete sealing components for full motor overhaul, including shaft seals, O-rings, gaskets, backup rings, brake piston seals and other dedicated sealing parts. Adopting imported high-performance NBR nitrile rubber and FKM fluororubber as core raw materials, this seal set delivers excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. It serves as a perfect direct replacement for original Nabtesco sealing parts, effectively eliminating external oil leakage, internal leakage and hydraulic pressure drop. It greatly extends the service life of GM38 travel motors under long-term heavy-load, high-vibration and harsh outdoor working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM38 travel motors and perfectly matched with standard OEM dimensions. No cutting, grinding or extra modification is required. It supports fast direct installation for routine maintenance and on-site emergency repair, saving assembly time and avoiding assembly failures caused by mismatched parts.
2. Premium Imported Sealing Materials.Core sealing components adopt high-quality FKM fluororubber and reinforced backup rings. The materials feature strong resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance continuously within the temperature range of -30°C to 120°C, adapting to complex temperature changes in construction sites.
3. Excellent High Pressure & Vibration Resistance.All sealing parts have passed strict 38MPa high-pressure and long-duration vibration simulation tests. It thoroughly solves common faults such as internal leakage and external oil seepage, stabilizes hydraulic system pressure, and ensures stable torque and power output of GM38 travel motors under heavy-load and continuous vibration working conditions.
4. Complete All-in-One Overhaul Kit.Integrated with all sealing accessories required for full disassembly and overhaul of the GM38 travel motor, including exclusive seals for integrated parking brake assemblies. The integrated package simplifies spare parts management, shortens overall equipment downtime, and effectively reduces daily operation and maintenance costs of construction machinery.
5. Rigorous Factory Quality Control.Every seal kit undergoes strict air tightness, high-pressure endurance and aging tests before delivery. All products comply with original factory quality standards. With stable batch consistency, it provides long-term reliable operation guarantee for engineering equipment.
6. Wide Application Scope.Designed for Nabtesco GM38 travel motors equipped on various medium and large construction machinery, widely applicable to:
• 18–25 ton class crawler excavators
• Kobelco SK200-8, SK210-8 and other mainstream excavator models
• Kato 1023-3 and other engineering vehicles
• General medium-sized mining machinery
• Mobile engineering machinery with wheel & crawler travel drive systems
• Outdoor construction equipment working under heavy-load and vibration conditions
