Product Overview
This high-performance overhaul seal kit is professionally engineered for Nabtesco GM17 travel hydraulic motors, which are widely equipped on construction machinery final drive systems. The complete set includes shaft seals, O-rings, gaskets, backup rings, friction component seals and all auxiliary sealing parts, fully supporting full disassembly, overhaul and routine maintenance of GM17 motors.
Adopting 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 serves as a perfect direct replacement for original Nabtesco sealing components. It effectively resolves typical failures such as external oil leakage, internal seepage and hydraulic pressure loss, and greatly extends the service life of GM17 travel motors under long-duration heavy-load, continuous vibration and harsh outdoor working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM17 travel hydraulic motors and strictly matched with standard OEM dimensions. No cutting, grinding or secondary modification is required. It enables fast direct installation for daily maintenance, regular overhaul and on-site emergency repair, saving assembly time and avoiding installation errors.
2. High-Grade Imported Sealing Materials.Core sealing parts adopt high-performance FKM fluororubber and reinforced structural backup rings. The materials feature strong resistance to hydraulic oil corrosion, high temperature fatigue and mechanical abrasion. It maintains stable and reliable sealing performance continuously within the full working temperature range of -25°C to 115°C, adapting to all kinds of seasonal and complex working environments of construction sites.
3. Outstanding High Pressure & Vibration Resistance.All sealing components have passed strict 35MPa high-pressure endurance tests and long-term vibration simulation tests. The optimized lip structure effectively eliminates internal and external oil leakage thoroughly, stabilizes hydraulic system pressure, and ensures steady torque and power output of GM17 travel motors under continuous vibration, impact and heavy-load operating conditions.
4. Integrated Full-Set Repair Kit.The package contains all sealing accessories required for complete motor overhaul, including special seals for built-in friction and braking components. The integrated packaging standardizes parts management, prevents missing individual parts during maintenance, shortens overall repair cycle and reduces the comprehensive operation and maintenance cost of engineering equipment.
5. Rigorous Factory Quality Control.Every GM17 seal kit undergoes air tightness test, high-pressure leakage test and aging test before delivery. All products comply with original factory technical standards. Strict quality inspection guarantees long-term stable operation of the motor after maintenance, reducing repeated maintenance frequency.
6. Targeted Application Scope.Specially designed for Nabtesco GM17 travel motors, widely applied to walking final drive systems of various heavy-duty construction equipment:
• Komatsu PC120-3, PC120-5 series excavators
• Medium and small sized crawler construction machinery
• Mobile engineering equipment with GM17 travel drive units
• On-site engineering machinery operating under outdoor and harsh working conditions
