IP Seals for Robots

Freudenberg Sealing Technologies' IPRS (Ingress Protection Seals for Robots) provides reliable protection for robotic systems operating in harsh environments. Designed to prevent dust, moisture, chemicals, and wear from compromising performance, IPRS extends service life and reduces maintenance. The adaptive Z-shaped geometry ensures sealing integrity under continuous motion, making it ideal for high-speed automation and outdoor applications. Manufactured with high-performance elastomers such as Fluoroprene XP and EPDM, IPRS offers exceptional resistance to lubricants, cleaning agents, and extreme temperatures. This makes it the perfect solution for six-axis robots, SCARA robots, AMRs, AGVs, and cobots. With its low-friction design and durable materials, IPRS enhances energy efficiency and operational reliability in industrial and autonomous robotics. Learn more about our IPRS Seals
