SKF Rod Seal PTB is a reinforced TPU U-cup rod seal for medium-duty hydraulic applications, designed to prevent leakage, maintain pressure up to 400 bar, support speeds up to 1 m/s, and ensure reliable cylinder performance in metric sizes.
SKF Rod Seal PTB is a reinforced U-cup stem seal made from TPU, designed for hydraulic rod sealing applications. It provides reliable leakage control and pressure retention in medium-duty hydraulic cylinders, supporting working pressures up to 400 bar (5,800 psi) and speeds up to 1 m/s.
The PTB seal uses a sealing ring material code U-1003 and X-ring material code A-8501. It is available in metric sizes and is suitable for hydraulic systems where stable sealing performance, durability, and equipment protection are required. Temperature suitability depends on operating conditions, pressure, speed, and system design.
JSPSEAL supplies SKF PTB rod seal replacement solutions for hydraulic cylinder maintenance and repair. With durable reinforced TPU construction and reliable pressure capability, these seals help reduce leakage, maintain system efficiency, and lower maintenance costs. For special temperature conditions, proper guiding, reduced operating parameters, or anti-extrusion rings may be recommended.
