Frequently Asked Questions

Q: What is the maximum operating temperature of the product?
A: Maximum temperature is 1200°C in oxidizing atmospheres and up to 1350°C in inert gases.

Q: Can the through-hole size be customized?
A: Custom through-hole sizes from Φ2mm to Φ25mm are supported, with accuracy up to ±0.01mm.

Q: How does it perform in vibrating environments?
A: The high damping characteristics of silicon nitride ceramic make it particularly suitable for vibrating environments, with better vibration damping than metals.

Q: Do you provide samples for testing?
A: Standard samples (maximum 2 pieces) are available for testing and verification.

Design Features:
This U-clamp block incorporates an ergonomic design where the symmetrical top protrusions facilitate robotic handling, and the bottom through-hole features a chamfer to prevent stress concentration. The internal U-groove undergoes special polishing to reduce friction wear with mating parts. The product undergoes strict heat treatment processes to prevent deformation or cracking in high-temperature environments, offering 3-5 times longer service life compared to traditional metal clamps.
