Flexible coupling: miniature bellow coupling
Rimtec

Zero-backlash miniature couplings provide today's high-speed, automated manufacturing applications with servo-quality stiffness, low inertia and an exceptionally long equipment life. Coupled with servomotors, stepper motors or gearboxes, our lightweight, stainless steel miniature couplings are ideal for machines with space limitations, and are widely used on encoders, robots, linear slides and other electrical equipment.

Rimtec's miniature couplings are uniquely designed to compensate for misalignment of the motor shaft when assembled, and to self-loosen and easily release when disassembled. Compared to traditional taper locks, this clamping style is extremely cost-effective, as it achieves highly accurate manufacturing tolerances, reduces bearing wear and machine downtime, and nearly eliminates the need to inventory replacement drives and other expensive assembly equipment.

The line transmits torque from 0.9 lb-in (0.1Nm) to 89 lb-in (10 Nm) on shaft sizes ranging from 1/32" (1 mm) to 7/8" (22 mm).
