Product Introduction
Pinless cycloidal technology is a reduction technology that maintains the core principle of a cycloidal reducer while simplifying the structure by reducing the number of pin components.
This technology focuses on reducing the increase in component count, assembly variation, and production process complexity that may occur in conventional pin-type structures. As a result, it enables the lightweight design and mass producibility required for ultra-compact reducers.
Bonsystems’ pinless cycloidal technology is a reduction solution suitable not only for drive units in space-constrained applications such as robotic hands, but also for the commercialization stage of robotics, where durability and productivity are essential.
In addition, as the technology is developed and manufactured based on domestic Korean engineering, it supports fast technical response and a stable supply system.
Based on 100% domestically developed Pinless Cycloidal Reduction Technology, we support reducer design tailored to the customer’s desired motor specifications and equipment structure.
