Open the catalog to page 1Tolomatic B3S & B3W Electric Rodless Actuators The Power to Move Heavy Loads The B3S and B3W electric rodless actuators have very large moment and load carrying capacities. The sealed recirculating ball bearing design makes it an excellent choice for challenging environments. For even higher capacity (loads up to 3,629 kg.) choose the Dual 180° Carrier and add an auxiliary carrier. Both actuators utilize a patented internal re-circulating ball bearing guidance system that provides extremely long life. These actuators are capable of carrying loads up to 3,629 kg [8,000 lbs]. A COMPARISON OF...

Open the catalog to page 3B3S RODLESS SCREW DRIVE ACTUATOR Endurance Technology features are designed for maximum durability to provide extended service life. The B3S rodless screw-drive electric actuator is designed for carrying moderate to heavy loads with large bending moment capacity. The B3S utilizes an integral recirculating ball bearing guidance system that provides durable performance and extremely long life. Choose from multiple screw technologies for thrust up 12 kN [2,700 lbf]. Built-to-order in stroke lengths up to 4.5 m [179 inches]. LOAD-BEARING CARRIER DESIGN • Load and moments are transmitted...

Open the catalog to page 7DYNAMIC BENDING MOMENTS AND LOADS A The Dual 180° carrier requires its own proprietary tube supports and foot mounts. See dimensional information. Breakaway torque will also increase when using the Auxiliary carrier or the Dual 180° carrier options. When ordering, determine working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated. Deflection Considerations: In applications where substantial Mx or My moments come into play, deflection of the cylinder tube, carrier and supports must be considered. The deflection factors shown...
