Cycloidal speed reducers combine a compact design with smooth motion and reliable performance. They’re built to handle continuous operation while keeping efficiency and stability over time. Their housing is made of high-quality cast iron (FC25), while larger models above size 620 use ductile cast iron (FCD45) for extra strength. Inside, the transmission components are made from SUJ2 bearing steel that’s heat-treated and ground to achieve consistent precision and wear resistance.

Thanks to their unique design, cycloidal drives distribute stress evenly across more than 60% of their components, compared to less than 5% in conventional gear systems. This makes them remarkably reliable under continuous or heavy-duty operation. Even after long periods of operation, these reducers continue to perform steadily until maintenance can be carried out at a convenient time. They offer reliable performance and peace of mind, even in tough or demanding working conditions.

    1. Cycloidal Speed Reducer (800 Series)
    2. Cycloidal Speed Reducer (800 Series) Cycloidal reducers for industrial y automation systems use a rolling contact design that greatly reduces sliding friction and vibration during operation. Since multiple teeth share the load at the same time, torque transmission is smoother and energy loss is minimized. Efficiency can reach over 96% for single-stage setups and around 92% for two-stage configurations. Discover more
    1. Speed Reducer for Centrifuge
    2. Speed Reducer for Centrifuge Cycloidal reducers for centrifuges are designed to keep these machines running smoothly and safely during continuous operation. They work by using a set of rotating pins and a ring gear to slow down the motor speed while increasing torque. This allows the centrifuge to spin evenly without vibration, even when handling heavy loads. Discover more

Selecting the right reducer depends on several factors:

  • First, check the torque requirement and choose a model that can handle it to avoid overloading.
  • The reduction ratio is also important, as it determines both the output speed and the precision.
  • If the application demands high accuracy, a low-backlash speed reducer is recommended.
  • Other points to consider include whether the operation is continuous or intermittent, and whether the reducer can be properly installed and integrated with your existing motor and equipment.

Lubrication helps reduce friction and wear, keeping the reducer in good working condition. For new units, the oil should be changed after 200–300 hours of operation. After that, replace it every 3000–6000 hours, depending on usage. When changing the oil, drain the old one completely, clean the tank and gears with a proper cleaning agent, and refill with high-quality lubricating oil that meets the reducer’s specifications.

Dirt, oil stains, and debris can accumulate on the surface and block heat dissipation, which affects performance. Wipe the outer surface with a dry cloth or use compressed air to remove buildup regularly. Avoid washing with water or letting any impurities get inside the reducer, as that could cause damage.

Inside a cycloidal reducer, the input shaft drives an eccentric disc surrounded by several pins that mesh with a cycloidal gear. The gear has an inner ring with teeth and multiple lobes. When the disc rotates, it makes the gear move eccentrically around the central axis, creating the speed reduction needed for the mixing process.

Cycloidal gearboxes offer high torque and power capacity in a much smaller size compared to conventional gearboxes. Their compact design allows conveyors to be installed in tighter spaces. Thanks to their different mounting options and output directions, they can easily be used in curved or inclined conveyor systems, helping save space and improve flexibility.

Yes. The reducer can be customized according to the power requirements and working conditions of various applications. The design process involves selecting the right type, structure, and dimensions to meet specific transmission needs. Factors such as stiffness, strength, and heat balance are also evaluated to ensure stable and long-lasting performance.
