Product Overview
This heavy-duty repair seal kit is tailor-made for Nabtesco GM18 travel hydraulic motors, a widely used low-speed high-torque final drive motor for excavators and construction machinery. It fits standard GM18 full-series displacement models and contains a complete set of sealing components for full motor disassembly, overhaul and routine maintenance.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber as core sealing materials, matched with reinforced backup rings. The kit delivers excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. It is a perfect direct replacement for original Nabtesco OEM seals. This seal kit effectively solves typical failures including external oil leakage, internal leakage and system pressure loss, and greatly extends the service life of GM18 travel motors under long-term heavy-load, frequent vibration and harsh outdoor working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM18 travel hydraulic motors and strictly matches OEM installation dimensions and part standards. No cutting, grinding or modification is required. It supports quick direct installation for regular maintenance, field overhaul and emergency on-site repair.
2. Premium Imported Sealing Materials.Core sealing parts adopt high-performance FKM fluororubber and wear-resistant reinforced backup rings. The materials resist hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance continuously within the operating temperature range of -30°C to 120°C.
3. Excellent High Pressure & Vibration Resistance.All components have passed strict 34.8MPa high-pressure and long-duration vibration simulation tests. It thoroughly eliminates internal and external leakage, stabilizes hydraulic system pressure, and ensures consistent torque and power output of GM18 motors under heavy-load and bumpy working scenarios.
4. Complete All-in-One Overhaul Kit.Equipped with all required sealing parts for full motor maintenance, including dedicated seals for integrated parking brakes. The integrated package unifies part management, shortens on-site repair time and effectively reduces the overall operation and maintenance cost of construction equipment.
5. Rigorous Factory Quality Control.Every seal kit is tested for air tightness, high pressure durability and aging resistance before delivery. All products comply with original factory quality standards, providing long-term stable operation guarantee for engineering machinery.
6. Wide Application Scope.Specially designed for Nabtesco GM18 travel motors installed on various construction and engineering equipment:
