Product Overview
This high‑performance repair seal kit is specifically designed for Sote 9S9T99 series low‑speed high‑torque radial piston hydraulic motors, covering displacement models from 180cc to 450cc per revolution. The kit includes complete shaft seals, O‑rings, gaskets, backup rings, wear rings and brake sealing components, enabling full motor overhaul and routine maintenance.
Constructed with imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal set delivers excellent oil resistance, high‑pressure resistance, wear resistance and aging resistance. It serves as a perfect direct replacement for original Sote seals, effectively resolving common faults such as external oil leakage, internal leakage and pressure drop. It extends the service life of 9S9T99 motors under prolonged heavy‑load and vibration‑intensive operating conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Sote 9S9T99 hydraulic motors, precisely matching standard OEM part numbers. No cutting or modification required, supporting quick direct installation for regular overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components adopt 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 -35°C to 115°C.
3. High Pressure & Vibration Resistance.All components undergo strict 38MPa 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 under harsh working conditions.
4. Complete All‑in‑One Repair Kit.Comes with all sealing accessories needed for full motor maintenance, including dedicated seals for integrated parking brakes. 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 Sote 9S9T99 hydraulic motors equipped on various heavy‑duty and engineering equipment:
