Cleco 520003 Pnuematic Spring Balance Arm | SBA-12-AH | Single Arm | 12" Extension

When a screwdriver station needs cleaner tool positioning and less wrist strain, the Cleco 520003 SBA-12-AH spring balance arm supports the tool weight while helping absorb fastening torque before it reaches the operator. This single arm model uses a spring-supported arm design for tools weighing up to 5 lbs. (2.3 kg), with a 10 ft-lbs. (13.5 Nm) torque capacity for light assembly fastening applications. The 12" arm extension helps keep the tool close to the work area, while the adjustable height configuration lets the station be set up for a more comfortable operating position.

Built for Cleco screwdriver balance arm installations, the SBA-12-AH uses ball bearing construction to make tool movement smoother and reduce the effort required to guide the tool over the fastener. A balance arm supports the tool from the arm assembly rather than the operator’s hand, helping improve repeatability at bench, cell, and light production workstations where the same fastening task is performed throughout the shift.
