TS7C-32 Clamp Type Rigid Coupling \u2013 Aluminum Alloy 32mm OD Heavy-Duty Split-Body Precision Coupler<\/h1>\n

The TS7C-32 clamp type rigid coupling<\/strong> is the largest and highest-torque model in the TS7C aluminum alloy clamp series, rated at 2 N\u00b7m nominal torque and 3,600 rpm maximum speed. With a 32 mm outer diameter, an overall length of 41 mm, and bore options of 10 and 14 mm, it serves medium-frame servo motor and gearhead output connections where the non-marring, distributed-clamp shaft grip of the TS7C design is required at higher torque levels. The M4 clamp screw thread \u2014 upgraded from M3 in the smaller TS7C frames \u2014 provides the clamping force necessary for reliable 2 N\u00b7m torque transmission without shaft surface marking.<\/p>\n

The TS7C-32 is distinguished from the TS7-32 setscrew equivalent primarily by its shaft interaction: where the setscrew applies focused point-contact force, the TS7C-32 compresses the bore uniformly around the full shaft circumference. This makes it the correct choice for applications where the connected shafts have precision-ground surfaces, hardened surfaces, or surface finish specifications that prohibit setscrew contact. At 50 g, the TS7C-32 is substantially lighter than its stainless equivalent (STS7C-32 at 158 g) and appropriate for most indoor dry or protected environments.<\/p>\n

At 3,600 rpm maximum speed, the TS7C-32 is suited to gearbox output shaft connections, rotary table drives, and servo motor connections where operating speed is within this limit. For applications requiring higher speed on larger shafts, the TS7-32 setscrew model at 10,000 rpm is the alternative. A full comparison is available on our product catalog<\/a>.<\/p>\n

M4 Clamp Screw and Extended Hub Length<\/h2>\n

\"TS7C-32<\/p>\n

The upgrade to M4 clamp screws at the 32 mm frame reflects the proportionally higher clamping force required for reliable 2 N\u00b7m torque transmission. M4 screws provide approximately 1.78\u00d7 the clamping load of M3 screws under the same hex key operation, ensuring the bore closes tightly and uniformly around the shaft across the full 12 mm hub engagement length. The 12 mm hub length \u2014 the longest in the TS7C aluminum series \u2014 distributes this clamping force over a larger shaft surface area, reducing bore-to-shaft contact pressure and improving the coupling’s long-term reliability under sustained and reversing torque loads.<\/p>\n

For the TS7C-32, the alternate incremental tightening installation sequence is particularly important. Fully tightening one clamp screw before the other can cause the split body halves to close unevenly, resulting in an oval bore cross-section that reduces effective shaft contact area and grip. Tighten in quarter-turn increments, alternating between the two clamp screws, until the specified tightening torque is reached on both.<\/p>\n

Typical Applications<\/h2>\n

    We use the TS7C-32 on workhead spindle encoder shaft connections. The precision ground encoder shaft surface must not be contacted by a setscrew \u2014 the TS7C-32 clamp is the specified solution. Zero-backlash performance has been confirmed across our production fleet, and the M4 clamp screws have maintained their tightening torque through our full machine service intervals.<\/p>\n

    Used in centrifuge drive shaft couplings requiring removal during rotor maintenance. The 14 mm bore matched our drive shaft and the clamp mechanism has held through repeated removal-reinstall cycles. The non-marring connection was the decisive factor over the setscrew version for our application.<\/p>\n
