Product Overview
This high-performance repair seal kit is specially designed for Inner Five-Star (Radial Piston) Hydraulic Motor 1600 (also known as GM5A-1600), a low-speed high-torque radial piston motor with a displacement of 1600cc/rev. The kit contains a full set of shaft seals, O-rings, gaskets, backup rings, piston seals and wear-resistant components, supporting complete motor overhaul and daily maintenance.
Adopting imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal kit features excellent oil resistance, high-pressure resistance, wear resistance and aging resistance. It is a direct OEM replacement for the original Inner Five-Star 1600 motor seals, effectively solving common problems such as external oil leakage, internal leakage and pressure drop. It extends the service life of the 1600 motor under long-term heavy-load, high-pressure and high-vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement,Fully compatible with original Inner Five-Star 1600 (GM5A-1600) hydraulic motors, precisely matching standard OEM part numbers. No cutting or modification required, enabling 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 within the temperature range of -30°C to 120°C.
3. High Pressure & Vibration Resistance.All components undergo strict 45MPa high-pressure and vibration simulation tests. It thoroughly eliminates internal and external leakage, stabilizes hydraulic pressure, and ensures consistent torque and power output of the motor in harsh environments.
4. Complete All-in-One Repair Kit.Comes with all sealing accessories needed for full motor maintenance, including dedicated piston seals and wear-resistant parts. The integrated package simplifies parts management, shortens repair time and reduces overall equipment operation and maintenance costs.
5. Strict Factory Quality Control.Each seal kit passes air tightness, high pressure and aging tests before delivery. All products comply with original factory standards, ensuring reliable long-term operation for industrial and construction machinery.
6. Wide Application Scope.Suitable for Inner Five-Star 1600 hydraulic motors equipped on various heavy-duty and engineering equipment:
