Product Overview
This high‑performance repair seal kit is professionally developed for Nabtesco GM05VA series low‑speed high‑torque radial piston hydraulic motors, widely used in excavator final drive travel systems. The kit contains complete shaft seals, O‑rings, gaskets, backup rings and brake sealing parts, supporting full motor overhaul and routine maintenance.
Adopting imported premium NBR nitrile rubber and FKM fluororubber 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. It effectively resolves common faults including external oil leakage, internal leakage and pressure drop, and extends the service life of GM05VA motors under long‑term heavy‑load and vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Nabtesco GM05VA hydraulic motors, matching standard OEM part numbers precisely. No cutting or modification needed, supports quick direct installation for regular overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components use high‑performance FKM fluororubber, reinforced backup rings and PTFE wear rings. The materials resist hydraulic oil corrosion, high temperature and fatigue, maintaining stable sealing performance continuously within the temperature range of -30°C to 120°C.
3. High Pressure & Vibration Resistance.All parts pass strict 45MPa high‑pressure and vibration simulation tests. It eliminates internal and external leakage thoroughly, keeps hydraulic pressure stable, 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 special seals for integrated parking brakes and valve plate assemblies. Integrated package simplifies parts management, shortens repair time and reduces overall equipment operation and maintenance costs.
5. Strict Factory Quality Control.Every seal kit undergoes air tightness, high pressure and aging tests before delivery. All products comply with original factory standards, delivering reliable long‑term operation for industrial and construction machinery.
6. Wide Application Scope.Suitable for Nabtesco GM05VA hydraulic motors equipped on various heavy‑duty and engineering equipment:
