145987-1

The 145987-1 O-ring seal from Yaskawa is crafted to provide a critical sealing solution for the S-axis in MOTOMAN RV series robots. This component is made from nitrile rubber (Buna-N), specifically engineered to withstand exposure to industrial dust and greases. With an AS568 standard cross-section of 2.62 mm, the O-ring supports effective sealing in demanding conditions.

The temperature operating range for this O-ring is between -20°C and +100°C, making it versatile for various applications. It boasts a hardness of 70 Shore A, which indicates its rigidity suitable for most industrial environments. In terms of fluid compatibility, it effectively handles hydraulic oils and greases while showing resistance to hydraulic fluids and mild solvents.

An essential feature of this O-ring seal is its ability to retain lubricants, thereby preventing leaks that could compromise robotic function. Installation requires a torque of 0.5 to 0.8 N·m for optimal placement. It has a dynamic friction coefficient of ≤0.35, contributing to reduced wear during operation. Furthermore, the design tolerates robotic duty cycles from 5 to 200 Hz, ensuring durability even under frequent movement conditions. Overall, the Yaskawa 145987-1 O-ring seal represents a strong choice for maintaining the operational integrity of robotic assemblies.
