Product Overview
This professional heavy-duty repair seal kit is tailor-made for Nabtesco GM23VL travel hydraulic motors, which are widely applied to final drive systems of construction machinery. The kit contains a full set of sealing components for complete motor disassembly, overhaul and routine maintenance, including shaft seals, O-rings, gaskets, reinforced backup rings, brake seals and all matched sealing accessories.
Adopting high-quality imported NBR nitrile rubber and FKM fluororubber as core sealing materials, this seal kit delivers excellent oil resistance, extreme pressure resistance, wear resistance and anti-aging performance. It serves as a perfect direct replacement for original Nabtesco factory seals. The product effectively resolves typical failures such as external oil leakage, internal seepage and system pressure loss, and greatly extends the service life of GM23VL motors under long-duration heavy-load, continuous vibration and harsh outdoor operating conditions.

Key Selling Points
1. 100% Exact OEM Direct Replacement.Fully compatible with original Nabtesco GM23VL travel motors and strictly matched with standard OEM part dimensions. No cutting, grinding or extra modification is required. It supports fast on-site installation for daily maintenance and emergency field repair, which greatly improves maintenance efficiency.
2. Premium Imported Sealing Materials.Core sealing parts are manufactured with high-performance 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 throughout the full temperature range of -25°C to 125°C, adapting to complex ambient temperatures of construction sites.
3. Excellent High Pressure & Vibration Resistance.All components have passed strict 38MPa high-pressure and long-cycle vibration simulation tests. The seal kit thoroughly eliminates internal and external oil leakage, stabilizes hydraulic system pressure, and ensures stable torque and power output of the travel motor under heavy-load, bumpy and continuous working scenarios.
4. Complete All-in-One Overhaul Kit.Equipped with all sealing accessories required for full motor maintenance, including special seals for integrated multi-disc brakes. The integrated package standardizes parts management, avoids missing individual components, shortens overall repair cycle and reduces the comprehensive operation and maintenance cost of equipment.
5. Rigorous Factory Quality Control.Every finished seal kit undergoes air tightness test, high-pressure endurance test and aging test before delivery. All products comply with Nabtesco original factory technical standards, providing long-term and reliable operation guarantee for engineering machinery.
6. Wide Application Scope.Specially designed for Nabtesco GM23VL travel motors installed on various heavy-duty construction and engineering equipment:
