TS7C-16 Clamp Type Rigid Coupling \u2013 Aluminum Alloy 16mm OD Split-Body Precision Shaft Connector<\/h1>\n

The TS7C-16 clamp type rigid coupling<\/strong> introduces a fundamentally different shaft retention mechanism compared to the TS7 setscrew series. Where the TS7 setscrew models use a single grub screw to apply point-contact clamping force against the shaft surface, the TS7C-16 employs a split-body clamp design: the coupling body is divided lengthwise by a precision slot, and M2 clamp screws draw the two halves of the bore together to compress uniformly around the shaft circumference. This distributed clamping force eliminates the shaft surface marking that is inherent to setscrew connections, allows the coupling to be repositioned axially without shaft damage, and provides a more repeatable installation torque-to-grip-force relationship across repeated removal and re-installation cycles.<\/p>\n

The TS7C-16 body is machined from aluminum alloy to a 16 mm outer diameter and 25 mm overall length, with a bore range of 5 and 6 mm covering the miniature instrumentation shaft sizes in this coupling’s torque class. At 8.2 g, it is the lightest body in the TS7C clamp series \u2014 notably lighter than the solid-body TS7-16 setscrew at 11 g despite carrying the same OD, because the material removed by the body slot more than offsets the clamp screw additions. Rated torque is 0.3 N\u00b7m nominal and 0.6 N\u00b7m maximum, identical to the TS7-16, at a maximum speed of 7,300 rpm \u2014 lower than the setscrew equivalent due to the inherent mass asymmetry of the split body but still appropriate for the encoder connections, stepper motor drives, and precision positioning axes that constitute the primary market for this frame size.<\/p>\n

For corrosion-resistant installations, the STS7C-16<\/strong> in 316 stainless steel provides equivalent performance. Both the TS7C and STS7C clamp coupling ranges are listed on our product catalog page<\/a>.<\/p>\n

Split-Body Clamp Design \u2014 Key Advantages<\/h2>\n

\"TS7C-16<\/p>\n

\n
\n

Non-Marring Shaft Connection<\/h3>\n

The clamp mechanism distributes gripping force uniformly around the shaft circumference, leaving no indentation or surface marking. This is critical for encoder shafts, where surface condition affects manufacturer warranty and bearing alignment, and for hardened shafts where setscrew contact would cause surface cracking.<\/p>\n<\/div>\n

\n

Repositionable Without Shaft Damage<\/h3>\n

The TS7C-16 can be loosened and moved axially along the shaft without leaving marks that would compromise the shaft surface for future installations. This flexibility is valuable in precision instrument design where fine axial adjustment of component position may be required during commissioning.<\/p>\n<\/div>\n

\n

Zero Backlash Rigid Connection<\/h3>\n

Despite the split body, the TS7C-16 delivers full rigid zero-backlash torque transmission. The clamp screws draw the body halves together with sufficient force to eliminate any play between the coupling body and shaft \u2014 angular position fidelity is maintained to the same standard as a solid-body rigid coupling.<\/p>\n<\/div>\n

\n

Ultra-Low Mass<\/h3>\n

At 8.2 g \u2014 less than the 11 g TS7-16 setscrew version \u2014 the TS7C-16 contributes negligible rotational inertia to the drive system. This is the lightest coupling in the TS7C range and particularly suited to the miniature drive trains in laboratory instruments and precision motion stages.<\/p>\n<\/div>\n<\/div>\n
