Inquiry (采购产品): Torsion coil spring Looking for a torsion coil spring (like a watch spring but much bigger in size) that is .25" wide (thickness of ga is not a concern), has a 3" inside diameter, OD can be 6"-10". The torsion coil spring must be able to provide 300 lb/in torque when it is under load. From the 300 lb/in preload position back off about 40 degrees, the torque of spring should be around 150-200 lb/in. Do you have a coil spring as stated above, or close to? **** Hidden Message ***** Wing Cheung 98155 Company: Boeing co E-mail: wing.cheung@boeing.com **** Hidden Message ***** wing.cheung@boeing.com
