Product Overview
This high-performance repair seal kit is professionally developed for Nabtesco GM07 series low-speed high-torque radial piston hydraulic motors (travel motors), widely used in excavator final drives. It covers displacement models ranging from 200cc to 450cc/rev. The kit contains complete shaft seals, O-rings, gaskets, backup rings, brake seals and other critical sealing components, enabling full motor overhaul and routine maintenance.
Adopting imported premium NBR nitrile rubber and FKM fluororubber (Viton) as core materials, the seal set features outstanding oil resistance, high-pressure resistance, wear resistance and aging resistance. It is a perfect direct replacement for original Nabtesco seals, effectively resolving external oil leakage, internal leakage and pressure drop, and extends the service life of GM07 motors under long-term heavy-load and vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM07 hydraulic travel motors, matching standard OEM part numbers precisely. No cutting or modification needed, supporting quick direct installation for regular overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components use high-performance FKM fluororubber (Viton) and reinforced backup rings. The materials resist hydraulic oil corrosion, high temperature and fatigue, maintaining stable sealing performance continuously within -30°C to 120°C.
3. High Pressure & Vibration Resistance.All parts pass strict 35MPa high-pressure and vibration simulation tests. It eliminates internal and external leakage thoroughly, stabilizes hydraulic pressure, and guarantees consistent torque and power output of the motor under harsh working conditions.
4. Complete All-in-One Repair Kit.Equipped with all sealing accessories required for full motor maintenance, including dedicated seals for integrated parking brakes and dust seals for harsh environments. The integrated package simplifies parts management, shortens repair time and reduces overall equipment O&M costs.
5. Strict Factory Quality Control.Every seal kit undergoes air tightness, high pressure and aging tests before delivery. All products comply with original Nabtesco factory standards, ensuring reliable long-term operation for industrial and construction machinery.
6. Wide Application Scope.Suitable for Nabtesco GM07 hydraulic travel motors equipped on various heavy-duty and engineering equipment:
