ABB 3HAC11216-2 Robot Balancing Cylinder

3HAC11216-2 is an ABB robot mechanical spare part described as a balancing cylinder. The same exact-model record also uses compensator cylinder and balancing unit; the complete reference identifies the requested component.

3HAC11216-2 is listed as a balancing cylinder for an ABB IRB 7600 robot. The listing does not identify every robot variant or mounting configuration, so the installed assembly must be matched by its complete reference.

3HAC11216-2 is described in its product record as a balancing cylinder, compensator cylinder and balancing unit. These names describe the mechanical balancing component; they do not establish an alternative ABB part number or a replacement relationship.

3HAC11216-2 has an exact-model product record identifying an IRB 7600 application. That record does not establish IRB 6650S compatibility. Select the part using the installed robot identification and balancing-assembly reference rather than a similar application name.

3HAC11216-2 should not be treated as interchangeable with another balancing-unit number solely because both parts are described as balancing cylinders. A documented reference correspondence and matching robot configuration are needed before selecting a different part.

3HAC11216-2 is a robot mechanical component. Installation planning belongs to the applicable robot service procedure and qualified maintenance personnel; this product identification does not specify an installation method, tightening torque, pressure setting or adjustment value.

3HAC11216-2 should be requested with the complete part number, quantity, clear label photographs, robot model and serial number, and the reference of the installed balancing assembly. These details support a component-specific quotation and application check.
