1. The dynamic load rating of zero backlash, preloaded screws is 63% of the dynamic load rating of standard non-preloaded screws. The calculated travel life of a preloaded screw will be 25% of the calculated travel life of the same size and lead of a non-preloaded screw for the same application. Preloaded follower is not available with absolute internal feedback.
2. A second anti-rotate arm is used on GSM30 10 inch and longer stroke, GSX40 12 inch and longer
3. 0.75 inch (20.32 mm) lead N/A above 12 inch (305mm) stroke on GSM40.
4. These housing options would typically be accompanied by the choice of the electroless nickel connectors if a connectorized unit were selected. This choice may also indicate the need for special material main rods or flanges.
5. Not available with extended tie rod mounting option.
6. Not available with holding brake unless application details are discussed with Exlar Applications Engineer.
