Product Overview
This premium overhaul seal kit is specially engineered for Nabtesco GM35VL variable axial piston travel hydraulic motors, which are widely assembled on final drive units of 20–22 ton class excavators. The complete kit covers all sealing components required for full motor disassembly, overhaul and routine maintenance, including shaft seals, O-rings, gaskets, backup rings, brake seals and other auxiliary sealing parts.
Manufactured with imported high-quality NBR nitrile rubber and FKM fluororubber as core raw materials, this seal set delivers superior oil resistance, extreme pressure resistance, wear resistance and anti-aging performance. It serves as a perfect direct OEM replacement for original Nabtesco sealing parts. The kit effectively resolves typical malfunctions such as external oil leakage, internal leakage and hydraulic pressure drop. It significantly extends the service life of GM35VL motors under long-duration heavy-load, frequent start-stop and vibration-intensive operating conditions on construction sites.

Key Selling Points
1. 100% Exact OEM Fit & Direct Replacement.Fully compatible with original Nabtesco GM35VL travel motors and final drive assemblies. All dimensions and specifications strictly match standard OEM parts. No cutting, grinding or extra modification is needed, enabling fast on-site installation for regular maintenance and emergency breakdown repair. It ensures seamless assembly and consistent operating performance as original parts.
2. Premium Imported Sealing Materials.Core sealing elements adopt high-performance FKM fluororubber and thickened reinforced backup rings. The materials feature excellent resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable sealing performance continuously within the temperature range of -25°C to 120°C, adapting to harsh outdoor working environments in different seasons and regions.
3. Outstanding High Pressure & Vibration Resistance.All sealing parts have passed strict 37.3MPa high-pressure endurance tests and vibration simulation tests. The optimized lip structure effectively eliminates internal and external leakage thoroughly, stabilizes hydraulic system pressure. It guarantees stable torque output and reliable operation of the motor under frequent impact, vibration and heavy-load working conditions of excavator travel systems.
4. All-in-One Complete Overhaul Kit.Equipped with all required sealing parts for full motor maintenance, including dedicated seals for the integrated normally closed parking brake and reduction gearbox. The integrated package avoids missing individual parts during repair, simplifies inventory management, shortens equipment downtime and reduces overall operation and maintenance costs of construction machinery.
5. Rigorous Factory Quality Control.Every seal kit undergoes air tightness testing, high-pressure durability testing and aging testing before delivery. All products comply with original factory quality standards. Each component is inspected one by one to eliminate defective products, providing long-term reliable operation for engineering equipment.
6. Wide Compatibility & Application Scope.Specially designed for Nabtesco GM35VL travel motors, widely applicable to mainstream 20–22 ton hydraulic excavators from multiple brands:
