Please provide a drawing of motor dimensions with all orders to insure proper mounting compatibility.
1. Mounting face size, shaft length and other details of particular motors may require special adapters or provisions for mounting. Always discuss your motor selection with Exlar engineering.
2. This option offers a true zero backlash follower for the FT Series actuator. The dynamic load rating of zero backlash, preloaded screws is 63% of the dynamic load rating of the 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 feedback options.
3. These housing options may also indicate the need for special material main rods, faceplate and motor mounting provisions. Consult Exlar Applications Engineering Department.
4. Max std. motor size FT35: 4 inch/115 mm, FT60 and 80: 8 inch/200 mm. For oversized motors, consult Exlar Applications Engineering.
5. NEMA callout must meet specifications or use alpha-numeric callout.
