Product Overview
This premium repair seal kit is professionally engineered for Nabtesco GM30VL low-speed high-torque travel hydraulic motors, a mainstream model widely equipped on medium and large construction machinery. The complete kit integrates shaft seals, O-rings, gaskets, backup rings, brake assembly seals and all matched sealing components, fully supporting complete overhaul and routine maintenance of GM30VL hydraulic motors.
Adopting imported high-performance NBR nitrile rubber and FKM fluororubber as core sealing materials, paired with reinforced backup rings, this seal kit delivers excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. It serves as a precise direct replacement for original Nabtesco sealing parts. The kit effectively solves typical motor faults such as external oil leakage, internal leakage and system pressure drop, and greatly extends the service life of GM30VL motors operating under long-term heavy-load, continuous vibration and harsh outdoor working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM30VL hydraulic travel motors and perfectly matches standard OEM part numbers. No cutting, drilling or extra modification is required. It enables fast direct installation for daily overhaul, field maintenance and emergency breakdown repair, which saves on-site working time efficiently.
2. Premium Imported Sealing Materials.Core sealing components are made of high-quality FKM fluororubber and reinforced structural backup rings. The materials feature outstanding resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance within the full temperature range of -30°C to 120°C, adapting to all kinds of complex ambient temperatures for engineering operations.
3. Excellent High Pressure & Vibration Resistance.All components have passed strict 38MPa high-pressure durability tests and long-cycle vibration simulation tests. The sealing structure can thoroughly eliminate internal and external oil leakage, stabilize hydraulic system pressure, and ensure stable torque and power output of GM30VL motors under continuous vibration, heavy load and frequent start-stop working conditions.
4. Complete All-in-One Repair Kit.The package contains all sealing accessories required for full motor maintenance, including special seals for integrated parking brakes. The integrated one-piece package standardizes parts management, avoids missing individual accessories during repair, shortens overall maintenance cycle and reduces the comprehensive operation and maintenance cost of mechanical equipment.
5. Strict Factory Quality Control.Every finished seal kit is inspected via air tightness test, high-pressure endurance test and aging test before delivery. All products comply with original factory technical standards and assembly tolerance requirements, providing long-term stable operation guarantee for engineering and construction machinery.
6. Wide Application Scope.Specially designed for Nabtesco GM30VL travel motors assembled on various medium and large heavy-duty engineering equipment, widely applied to:
