ACBAR Eccentric Gearboxes
Achieve backlash-free, highly dynamic movements with maximum repeatability.
When extreme reductions, high shock loads, and maximum robustness are required, ACBAR Eccentric Gearboxes are used
The ACBAR Eccentric Gearboxes from AKIM were developed for applications where traditional gearboxes reach their limits. Thanks to cycloidal motion and rolling power transmission, they reliably absorb high torques and extreme load changes – with smooth operation and compact design.

Our solutions are generally based on modified standard gearboxes, which we adapt to the dimensions, torque, or interfaces of your application – saving time and budget. And if your project requires more, we will jointly develop a special gearbox.
Benefits of ACBAR Eccentric Gearboxes
ACBAR is more than a gearbox – it is a robust solution for extreme demands.
Even Load Distribution
The rolling power transmission avoids point gear contacts and reduces wear even under high loads.
High Overload and Shock Resistance
ACBAR Eccentric Gearboxes are designed for frequent load changes and extreme shock loads – without impairing function.
Compact Design with High Reduction
Very high ratios are realized in one stage – space-saving and constructively efficient.
Smooth Operation
The cycloidal motion ensures even power transmission and low vibrations, even under load.
Durability in Continuous Operation
ACBAR gearboxes are designed for continuous operation and have been in use for decades.
Typical Areas of Application
Drive Systems for Mobile Machines
Reliable power transmission under high loads, frequent load changes, and harsh operating conditions.
Hoists and Winch Drives
High overload safety and controlled movement with heavy loads and changing loads.
Rotary and Swivel Drives
Smooth operation and robust design for swivel movements under high torques.
Conveyor Technology and Positioning Systems
High availability and long-lasting operation in continuous use and changing loads.

Frequently asked questions about AKIM Solutions
For which applications is an ACBAR eccentric gearbox particularly suitable?
ACBAR eccentric gearboxes are suitable for applications with high gear ratios, strong shock loads, and continuous operation. Typical examples include travel, lifting, and slewing drives in harsh industrial environments.
How does ACBAR differ from traditional gear transmissions?
Unlike gear transmissions, power transmission in ACBAR is rolling and cycloidal. This results in a more even distribution of loads, leading to higher overload safety and longer lifespan.
Are ACBAR gearboxes maintenance-intensive?
No. ACBAR eccentric gearboxes are lubricated for life and are almost maintenance-free under normal operation. This reduces downtime and operating costs.
Can existing ACBAR gearboxes be replaced or upgraded?
Yes. AKIM offers retrofit solutions, spare parts, and repairs even for older ACBAR models – including gearboxes that have been in use for decades.
Are there spare parts for old/older AKIM gearboxes?
Yes. We supply spare parts even for gearboxes from the 1920s – our documentation is complete/comprehensive and archived.
