Cleco 520006 Pneumatic Spring Balance Arm | SBA-18-AH | Single Arm | 18″ Extension

When a light fastening station needs controlled reach and reduced tool handling effort, the Cleco 520006 SBA-18-AH spring balance arm helps keep the screwdriver positioned over the work while supporting tool weight throughout repeated assembly tasks. This single arm model is built for tools weighing up to 5 lbs. / 2.3 kg and provides a 10 ft-lbs. / 13.5 Nm torque capacity, helping absorb torque reaction, which is the twisting force created when a fastener reaches resistance. Its 18″ extension gives operators more working reach than the 12″ version while maintaining a compact single-arm workstation layout.

The SBA-18-AH combines spring-supported balance with ball bearing construction for smoother tool movement during repetitive screwdriving, run-down, and light assembly work. The adjustable height post style helps position the suspended tool at a better working level for the operator, making it useful for benches, fixtures, and production cells where tool access and repeatability matter.

Applications:

• Assembly benches — supporting lightweight pneumatic screwdrivers during repeated screw installation, run-down, and torque-controlled fastening.
• Production work cells — keeping the tool suspended and ready where operators move between nearby fastener locations.
• Electronics and appliance assembly — improving tool placement for close-range fastening on panels, housings, brackets, and small assemblies.
• Automotive component assembly — supporting light screwdriving tasks on trim, subassemblies, fixtures, and low-torque production work.
• Repair and MRO stations — keeping frequently used screwdrivers organized, accessible, and off the bench surface between fastening operations.

FAQs:

• Q: What is the difference between the Cleco SBA-18-AH and SBA-12-AH?A: The SBA-18-AH has an 18″ B dimension, while the SBA-12-AH has a 12″ B dimension. Choose the 18″ model when the tool needs a longer reach from the mounting post.
• Q: What tool weight can this balance arm support?A: The SBA-18-AH supports tools weighing up to 5 lbs. / 2.3 kg. Include the weight of the tool, air fitting, and any attached accessory when checking the load.
• Q: What does adjustable height mean on this model?A: Adjustable height means the post-mounted arm can be positioned vertically to better match the operator, work surface, and fastening location.
• Q: Is this balance arm meant for torque reaction control?A: Yes, within its published rating. The SBA-18-AH is rated for 10 ft-lbs. / 13.5 Nm of torque capacity, making it suitable for light fastening applications within that range.
