143147-1

The Yaskawa part number 143147-1 is a safety spring intended for robotics applications. It serves as a critical component that ensures safety during operation by providing necessary deflection when force is applied. The maximum permitted deflection is 12 mm, which allows for flexibility in various scenarios.

This spring end type is closed and ground, which enhances reliability and stability within robotic systems. Compatibility with Yaskawa’s XRC, DX100, and DX200 controllers makes it an integral piece of equipment, facilitating integration with a teach pendant grip assembly.

Constructed from high-carbon spring steel, the spring features a zinc/nickel plated surface treatment that helps resist corrosion and wear over time. It boasts a dimensional tolerance with an axial deviation of ±0.1 mm, ensuring accurate fit and function. The operating cycles are rated to exceed 100,000, affirming durability in high-frequency applications.

The temperature operating range of this spring extends from -10°C to +80°C, making it versatile for different environments. With an activation force that operates between 15 and 25 Newtons, the spring achieves a linear force profile characterized by its spring rate (k-value). An important safety feature is its rapid response time of less than 500 milliseconds to initiate emergency stops, contributing to overall operational safety.
