What HKS does

HKS Dreh-Antriebe GmbH is a privately held, third-generation family-owned German manufacturer of hydraulic, pneumatic, and mechanical rotary actuators and drive systems, headquartered in Wächtersbach-Aufenau with a second production facility in Neukirch/Lausitz. The company designs, develops, and manufactures rotary actuators (Drehantriebe), tiltrotators, rack-and-pinion actuators, and rotary-lift combinations using a proprietary steep thread principle (Steilgewindeprinzip) and rack-and-pinion mechanisms, with surface-hardened gear pairings rated up to 250,000 Nm torque, 1,500° rotation angle, and 350 bar operating pressure. It also produces a parallel line of excavator attachments — TiltRotator, XtraTilt, and RotoBox — along with supporting accessories including the XtraSense 2D/3D/GPS sensor system and XtraFlow oil feedthrough, targeting OEMs and end-users across construction machinery, industrial machine building, on-/offshore valves, mobile hydraulics, mining, energy, food/pharma/chemical, automation/robotics, and waste collection vehicles. The company self-identifies as world market leader in hydraulic rotary actuators.

The business model is built on custom-engineered hardware sales with near 100% in-house production depth in Germany, supplemented by aftermarket parts and on-site service. Go-to-market is sales-led through an international sales-partner network in more than 20 countries (generating over 54% of revenue abroad) combined with direct enterprise sales from headquarters, supported by a 10-person engineering department that consults on drive selection from concept through after-sales. Pricing is not publicly disclosed and is configured per application. The company holds DIN EN ISO 9001:2015 certification, has been operating since 1970, and currently employs 290+ people across roughly 10,000 m² of production space; it has no external investors, no disclosed funding rounds, no M&A activity, and no public listing.

Core offering

HKS Dreh-Antriebe GmbH designs, develops, and manufactures hydraulic, pneumatic, and mechanical rotary actuators (Drehantriebe), tiltrotators, rack-and-pinion actuators, and rotary-lift combinations. The portfolio is custom-engineered with up to 250,000 Nm torque, 1,500° rotation, and 350 bar operating pressure, produced in Germany with near 100% production depth, and sold to industrial OEMs, construction equipment users, and mobile hydraulics customers globally through direct sales and an international partner network.

Product overview

HKS Dreh-Antriebe GmbH offers a comprehensive portfolio of hydraulic and pneumatic rotary actuators and related mechanical drive solutions, all manufactured in Germany. The core product line includes multiple series of rotary actuators (I-DA-H, DA-H, DA-H-AL, DKA) for industrial applications and the M-DA-H series for mobile hydraulic applications, available in numerous variants (F1-F10) with different mounting configurations. For construction machinery, HKS provides TiltRotator, XtraTilt (tilting), and RotoBox (continuous rotation) attachments with supporting accessories like XtraSense sensors and XtraFlow oil feedthroughs. The on/offshore product line (SA-H series, AFR) serves valve and armature applications. Rack and pinion actuators (DEK, DZK) handle highest torque requirements, while rotary lift combinations (DHK-H) enable combined rotation and lifting. The product ecosystem is complemented by hydraulic cylinders and custom manufacturing services. All products share common engineering principles—steep thread or rack-and-pinion technology—and can be configured with options like end-position damping, angle adjustment, and sensor integration. Technical specifications include operating pressures up to 350 bar, torques up to 250,000 Nm, and rotation angles up to 1,500°. As a vertically integrated manufacturer with near 100% production depth, HKS offers extensive customization capabilities through its 10-person engineering department.
