Notes: ^ 1.) Ballscrew load is rated dynamically for 1,000,000 inches of travel. 2.) Maximum capacities calculated based on optimum motor torque, ballscrew
lead, 3.) Consult factory for speeds over 2,000 RPM. 4.) 37-inch stroke unit is rated for 1,650 RPM maximum. 5.) 49-inch stroke unit is rated for 1,650 RPM maximum. 6.) 1:1 ratio on all in-line linear positioners. 7.) Indicates an available option. Please consult Comptrol for application assistance, pricing and delivery on both standard and non-standard requirements. |
