TS7-32 Setscrew Rigid Coupling \u2013 32 mm OD Heavy-Duty Precision Aluminum Alloy Coupler<\/h1>\n

The TS7-32 setscrew type rigid coupling<\/strong> is the largest of the four standard aluminum alloy frames in the TS7 series aside from the TS7-40, rated at 2 N\u00b7m nominal torque and 10,000 rpm maximum speed. With a 32 mm outer diameter and bore range of 12, 14, 15, and 16 mm, this coupling connects medium-frame servo motors, compact gearbox output shafts, and leadscrew assemblies in industrial automation, packaging machinery, and multi-axis CNC systems. The M4 setscrew thread is retained at this frame size, tightened to 1.7 N\u00b7m \u2014 the same as the TS7-25 \u2014 with the increased body mass and wall thickness at 32 mm OD providing additional mechanical support for the higher torque load.<\/p>\n

At 71 g total mass and 9.1 \u00d7 10\u207b\u2076 kg\u00b7m\u00b2 rotational inertia (calculated at maximum 16 mm bore), the TS7-32 remains lightweight relative to its torque capacity. In servo axis inertia ratio calculations, this figure should be reflected into the motor shaft and compared against the motor rotor inertia to confirm adequate servo loop stability. For most medium-frame servo motors in the 200\u2013750 W range, the TS7-32 coupling inertia is negligible relative to the load-side inertia.<\/p>\n

The stainless steel equivalent STS7-32<\/strong> delivers the same performance envelope at 190 g in 316 stainless steel construction. The complete dimensional and parametric comparison between all TS7 frame sizes is available on our product listings page<\/a>.<\/p>\n

\"TS7-32<\/p>\n

Design Rationale<\/h2>\n

The TS7-32 is the natural progression from the TS7-25 for applications requiring the 12\u201316 mm bore range without stepping up to the TS7-40 frame. The 10 mm hub length per side \u2014 increased from 9 mm on the TS7-25 \u2014 extends shaft engagement to support the higher torque capacity reliably. The 32 mm OD maintains compatibility with the vast majority of servo motor end-bell pilot diameters in this torque class, making motor-mounted encoder couplings a common installation scenario.<\/p>\n

One characteristic of the setscrew locking mechanism at larger shaft diameters is that the contact area between setscrew tip and shaft is a relatively small fraction of the shaft circumference. For applications with sustained reversal torques approaching the rated 2 N\u00b7m, the use of a shaft with a machined flat \u2014 aligned with the setscrew contact point \u2014 is strongly recommended to improve slip resistance and protect the shaft surface from point deformation.<\/p>\n

    Germany \u2014 Industrial Packaging Machine Builder<\/p>\n

    We use the TS7-32 to couple medium servo motors to the encoder shafts on our case erecting machine drives. The coupling has to handle frequent direction reversals at up to 1.8 N\u00b7m \u2014 well within its rated capacity. After 18 months of production, none of the installed units have required replacement or re-tightening.<\/p>\n

    We retrofit older VMC spindles with new servo encoder feedback systems and the TS7-32 has become our standard coupling choice for the 15\u201316 mm encoder shaft connection. The zero-backlash performance is consistent and the dimensions are accurate \u2014 no fitment surprises on installation.<\/p>\n

    Used in joint 3 and joint 5 of a 6-axis SCARA robot arm rebuild project. The TS7-32 handled the torque and speed requirements and the lightweight aluminum body kept the arm’s inertia figures within our dynamics model. The 14 mm and 16 mm bore options matched our motor and gearhead shafts without modification.<\/p>\n
