JAKOB Antriebstechnik
Servo Couplings — Metal Bellows
Zero-backlash metal bellows couplings for precise motion — 0.4 to 65,000 Nm.
For over 50 years, family-owned JAKOB Antriebstechnik (Kleinwallstadt, Germany) has been the name behind the metal bellows coupling — a product they invented. JAKOB servo couplings connect machine axes with zero backlash and high torsional stiffness, so motion stays exact, while the flexible bellows forgives shaft misalignment without vibration or wear.
The maintenance-free all-metal design covers nominal torques from 0.4 to 65,000 Nm, high-speed versions run to 30,000 rpm, and high-temperature and stainless steel variants suit cleanroom and semiconductor use. JAKOB Antriebstechnik products are supplied in Southeast Asia by ISA Technology.
