It has high mechanical efficiency and the torques that they are able to produce range from a couple of Nm to multiple thousands of Nm.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nHowever, one potential drawback of the rack-and-pinion design is backlash. Backlash occurs when rack and pinion gears are not completely aligned and there is a small gap between each geared connection. This misalignment can cause wear on the gears during the life cycle of the actuator, which in turn increases backlash.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA double rack unit uses a pair of racks on opposite sides of the pinion. This helps eliminate backlash due to a counter force and also doubles the output torque of the unit and increases the mechanical efficiency of the system.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Single Acting vs Double Acting<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn a single-acting actuator, the air is only supplied to one side of the piston and is responsible for the movement of the piston in only one direction. The movement of the piston in the opposite direction is performed by a mechanical spring. Single-acting actuators conserve compressed air but perform work in only one direction. A downside of single-acting cylinders is the inconsistent output force through a full stroke due to the opposing spring force.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn a double-acting actuator, the air is supplied to chambers on both sides of the piston(s). Higher air pressure on one side can drive the piston(s) to the other side. Double-acting actuators are used when work needs to be performed in both directions.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOne of the advantages of double-acting cylinders is the constant output force through a full rotation range. The drawbacks of double-acting cylinders are their need for compressed air for movement in both directions and a lack of a defined position in case of a power or pressure failure.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>General Troubleshooting Procedure<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:table {\"className\":\"is-style-stripes\"} -->\r\n<figure class=\"wp-block-table is-style-stripes\">\r\n<table>\r\n<tbody>\r\n<tr>\r\n<td class=\"has-text-align-center\" data-align=\"center\">Problems<\/td>\r\n<td class=\"has-text-align-center\" data-align=\"center\">Inspection<\/td>\r\n<td class=\"has-text-align-center\" data-align=\"center\">Solutions<\/td>\r\n<\/tr>\r\n<tr>\r\n<td class=\"has-text-align-center\" data-align=\"center\">Pneumatic valve isn't working<\/td>\r\n<td class=\"has-text-align-center\" data-align=\"center\">The solenoid valve or its coil is damaged.\/The solenoid ports are plugged.<\/td>\r\n<td class=\"has-text-align-center\" data-align=\"center\">Replace the solenoid valve or its coil.
