Flexible coupling: metal bellow coupling
Rimtec

Rimtec’s zero-backlash couplings provide servo-quality stiffness and low inertia for highly dynamic servo and vector drives … but without the misalignment problems that are common with traditional metal bellows couplings.

This high-performance line incorporates a unique taper lock design, which self-centers the motor shaft when assembled, and self-loosens to easily release when disassembled.

Compared to ordinary taper locks, this special clamping style is extremely cost effective in conjunction with Rimtec’s high-end couplings – it achieves highly accurate manufacturing tolerances, dramatically reduces bearing wear, slashes downtime, and practically eliminates the need to inventory replacement drives.
Metal bellows couplings transmit torque from 159.3 lb-in (18 Nm) to 44,250 lb-in (5000 Nm), on shaft sizes from .04 inches (1 mm) up to 4 inches (100 mm).
