Read MoreThe Dunkermotoren PLG 42S Series Planetary Gearbox is a compact, high-performance gear solution designed for precision applications requiring consistent torque delivery and long-term reliability. With reduction ratios ranging from 4:1 to 512:1 and continuous torque handling up to 14 Nm, this steel ring-gear gearbox is ideal for robotics, medical devices, and industrial automation systems.
Key features include straight-toothed gearing across all stages for smoother operation, an output shaft supported by dual ball bearings for increased load capacity, and lifetime lubrication for maintenance-free use. The PLG 42S is available in 1-, 2-, and 3-stage configurations, enabling flexible adaptation to speed and torque requirements while delivering high efficiency—up to 90% in single-stage versions.
With axial and radial load capacity rated at 150 N and 250 N respectively (measured from the shaft center), the PLG 42S gearbox is designed to perform reliably under demanding load conditions. Its IP50 protection rating and optional configurations, including food-grade and low-temperature lubrication, further support operation in diverse environments.
For engineers and OEMs seeking robust, space-saving gear solutions with high torque density, the PLG 42S Series offers an ideal balance of strength, precision, and durability.
