ASRaymond Torsion Spring T072-210-500

Stock sizes in stainless steel and music wire SPEC stainless steel torsion springs are widely useful to store and release energy of rotation or to maintain a pressure over a short distance. Our stock selection includes torsion springs with four end positions and music wire springs with three end positions as shown in the drawings. SPEC torsion springs are normally used over a supporting mandrel or arbor. Suggested mandrel sizes allow about 10% clearance at the deflections listed. If greater deflections are used, the arbor size should be reduced. Sufficient room (minimum axial space) must be provided in the assembly for the spring to function properly. SPEC torsion springs should be used in the direction that winds the coils. In the unwinding direction that winds the coils. In the unwinding direction the maximum load is lower because of residual stresses. Torque values listed are suitable for average conditions. These values can be increased about 20% for static conditions with only slight setting.
