Product Overview
This high‑performance repair seal kit is custom‑engineered for Inner Five‑Star (Radial Piston) Motor 1300, a low‑speed high‑torque radial piston hydraulic motor with a displacement of 1300cc/rev. It contains a full set of shaft seals, O‑rings, gaskets, backup rings, wear rings and critical sealing components to support complete motor overhaul and routine maintenance.
Built with imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal kit delivers outstanding oil resistance, high‑pressure resistance, wear resistance and aging resistance. It serves as a direct OEM replacement for original Inner Five‑Star Motor 1300 seals, effectively solving common issues such as external oil leakage, internal leakage and pressure drop. It extends the service life of the 1300 motor under prolonged heavy‑load, high‑pressure and high‑vibration operating conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Inner Five‑Star Motor 1300, precisely matching standard OEM part dimensions. No cutting or modification required, enabling quick direct installation for scheduled overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components adopt high‑performance FKM fluororubber, reinforced backup rings and PTFE wear rings. These materials resist hydraulic oil corrosion, high temperature and fatigue, maintaining stable sealing performance across -30°C to 120°C.
3. High Pressure & Vibration Resistance.All components undergo strict 45MPa high‑pressure and vibration simulation tests. The kit 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.Includes all sealing accessories required for full motor maintenance, including dedicated seals for valve plate and bearing assembly. The integrated package simplifies parts management, shortens repair time and reduces overall equipment O&M 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 Motor 1300 equipped on various heavy‑duty and engineering equipment:
