Custom Sumitomodrive Cyclo Inline Servo Gearbox Manufacturer, Suppliers

The Sumitomodrive Cyclo Inline Servo Gearbox is a high-reliability inline servo gearbox based on the exclusive Cyclo® cycloidal disc mechanism. It has two series (standard-backlash and low-backlash) to meet diverse needs, with a maximum reduction ratio of up to 658,503:1 and a 500% momentary shock load capacity. It supports a maximum input speed of 4,000 rpm and a maximum torque of 603,000 N⋅m, and is compatible with both keyless and keyed motor shafts. It also allows multiple installation methods and arbitrary mounting directions, requires little maintenance, and is widely used in food machinery, automotive plants, conveyors and other industrial scenarios.

Product Description

Product Overview

Sumitomodrive Cyclo Inline Servo Gearbox is a high-performance inline servo gearbox based on Sumitomo's exclusive Cyclo® cycloidal disc mechanism. It stands out for its strong shock resistance, wide range of torque and reduction ratio, and dual-series options. It is widely used in motion control scenarios requiring precision and stability. The key features include:

Core Structural Advantage

It adopts a unique cycloidal disc structure. Different from ordinary involute gears, the cycloidal disc has a smooth curve, and the internal gear uses a special circular arc tooth profile. This design makes the load spread over 2/3 of the reduction components, realizing smooth rolling contact, which can effectively prevent tooth breakage. At the same time, it can withstand 500% momentary shock load, and has better durability and longer service life than traditional gearboxes. Some models are filled with grease, realizing maintenance-free operation.

Outstanding Performance Parameters

Wide reduction ratio range: The overall product line can achieve a maximum reduction ratio of up to 658,503:1, which can meet the speed reduction needs of various high-ratio industrial scenarios. High input speed & large torque: The maximum input speed can reach 4,000 rpm, and the maximum torque can reach 603,000 N·m, which can match the power output of different servo motors. Flexible installation: It supports multiple installation methods such as foot mount, case mount and flange mount, and can be installed in any direction.

Strong Compatibility & Easy Assembly

It is compatible with both keyless and keyed motor shafts. The equipped adapter can be matched with servo motors of all manufacturers, which is convenient for users to assemble independently. There is no need to modify the equipment structure too much during replacement and upgrading, reducing the cost of equipment transformation.

Typical Application Scenarios

Relying on its advantages of high precision, strong shock resistance and compact structure, it is widely used in demanding industrial fields. It is suitable for food processing, automobile manufacturing, warehousing and logistics conveying equipment. It can also be applied to precision motion control systems such as industrial robots and automated production lines, as well as heavy-duty scenarios that require frequent load changes and high shock resistance.
