KTR PACEX 65 Precision Bellows Coupling — Ultra-Low Backlash for CNC and Medical Equipment

KTR PACEX 65 Precision Bellows Coupling — Ultra-Low Backlash for High-Precision Saudi Manufacturing

The KTR PACEX 65 is a precision bellows coupling designed for applications requiring ultra-low backlash (less than 0.05 degrees) and high torsional stiffness for indexing and positioning applications. For Saudi precision manufacturing sector — CNC machining centers, laser cutting machines, and automated assembly equipment — PACEX 65 provides positional accuracy for tight-tolerance parts.

Saudi growing CNC machine tool industry in Dhahran and Jeddah industrial cities uses PACEX 65 on high-performance servo spindle drives where even small amounts of backlash cause dimensional errors in machined parts.
