Bimba Manufacturing ACH500 Split Hex Rod Coupler

The Bimba ACH500 Split Hex Rod Coupler is an alignment coupling designed to join a pneumatic or hydraulic cylinder rod to a mating rod end using a split-hex design for secure clamping and straightforward installation. It is the ACH variant in Bimba’s AC/ACH alignment coupler family and shares the 1/2-20 thread size associated with the AC500 series, with ordering guidance explicitly stating to specify AC or ACH when ordering. Key dimensions include a hex dimension (H) of 2.156 inches and an overall footprint near 1.250 by 2.00 inches, enabling a compact yet sturdy fit in actuator assemblies. The AC500 family lists a maximum pull rating of 4,841 pounds at a 3:1 safety factor, illustrating the level of load transfer the coupling supports when paired with compatible 1/2-20 connections. Common applications involve attaching a rod end accessory or fixture to a cylinder rod in motion-control or automation setups where precise alignment is required and some misalignment must be accommodated without sacrificing strength. The split-hex design provides a clamp-style connection that can be installed or removed with relative ease, making the ACH500 suitable for quick-change setups in tight spaces within machine and automation environments.
