balance arms balance arms absorb torque support weight and improve productivity cleco balance arms are engineered to deliver longer service life using durable components rugged design and operator-sensitive features these arms absorb the torque produced by the screwdriver eliminating torque reaction to the operator balanced by springs or air cylinders the arm and not the operator supports the weight of the tool by reducing the fatigue factors operator productivity is improved tool movement and placement over the fastener is virtually effortless since most moving parts of the balance arm are mounted on ball bearings access to the tool is easily changeable by adjusting the springs or cylinder supporting the forearm arm components and materials are selected for strength and rigidity precision aluminum sand castings used in the articulating arm section are light but sturdy over 60 models of the cleco balance arms are available air cylinder models are capable of supporting tools weighing up to 10 lbs 4.5 kg spring models will support tools weighing up to 5 lbs 2.3 kg both styles have torque capacities of 10 ft lbs 13.5 nm arms can be post mounted wall mounted or mounted on an adjustable height post tool holders for all models will accommodate most major brands of air tools straight and pistol balance arm operating envelope model r1 max in mm r1 min in mm r2 max r2 min in mm in mm h max in mm h min in mm sba-12 24 610 sba-18 30 762 pba-12 26 660 pba-18 32 813 2 51 18 457 6 152 20 508 3 76 20 508 8 203 22 559 r1 max 8 203 15 381 7 178 15 381 7 178 17 432 6 152 17 432 6 152 0 2 0 51 8 203 tool holders selecting the proper tool holder for the tool used on cleco balance arms enhances the ergonomic benefits of the arm tool holders allow the tool to swing swivel and rotate enabling the operator to work more comfortably and productively standard and extended tool holders are available for parallel balance arms both models hold the tool perpendicular to the work and are ideal for self-tapping and thread forming applications tool diameter capacity is up to 1 3/4 inch 45mm manifold tool holders used on sba and csba balance arms suspend the tool from the air inlet they allow the tool to swing or swivel when equipped with the optional swivel assembly for ease of tool movement 71 r1 min h max r2 min h min r2 max
