What is the Sumitomo BK2-20B-01MEKA?
This is a precision gear reducer. It is made by Sumitomo Heavy Industries. They are a famous Japanese brand. This part connects to a servo motor. It slows down the speed and increases the torque. The ratio is 1:20. This means the output shaft turns 20 times slower than the motor. But the power (torque) is 20 times stronger.
This specific model is the BK2-20B-01MEKA. The “BK2” series is very popular. It is compact and strong. It uses cycloidal or involute gear technology. This makes it run smoothly with very little backlash. Backlash is the wiggle in the gear. You want zero backlash for precision work. This part is perfect for robotics, CNC machines, and packaging lines. It is a used part, but it is built like a tank. It will last for years if you maintain it.

Why Buy Used Parts from Japan?
You might ask, “Why not buy a new Chinese copy?” The answer is quality. Japanese factories run machines 24/7. They take care of their tools. When a machine is upgraded, the old parts are removed. These parts still have 80% to 90% of their life left.
Japanese used parts are different. They are not “junk.” They are “decommissioned assets.” The metal is better. The bearings are higher grade. The gears are cut with precision. A new cheap reducer might fail in 6 months. A used Sumitomo can run for 10 years. You save money. You get OEM quality. It is the smart choice for factory managers.
We clean every part. We check the bearings. We test the oil. If it is bad, we change it. You get a part that works, not a part that looks good in a box.
Where Does This Reducer Fit?
This 1:20 ratio is very common. It is used in many machines. Here are the top scenarios where we sell this part:
- Cable Extrusion Lines: You need precise speed control for the haul-off capstan. This reducer provides the high torque needed to pull thick cables without slipping.
- Robotic Arms: For the wrist or elbow joints. The 1:20 ratio gives the robot the strength to lift heavy payloads while keeping the motor small and fast.
- CNC Rotary Tables: Indexing heavy workpieces. You need rigid positioning. This gearbox handles the load.
- Packaging Machinery: Form-fill-seal machines. The servo motor needs to sync with the film movement. The reducer ensures perfect timing.
- Conveyor Systems: Heavy load transfer. If you have a steep incline, you need the torque to move boxes or pallets.
If your machine has a Sumitomo servo motor with a gearbox, this is likely the match. The BK2 series is a standard workhorse in Asian factories.
How We Pack and Ship
We know shipping is scary. Parts get broken. We fix that. We pack like the Japanese do. It is simple but strong.
First, we wrap the reducer in anti-rust paper. Japan is humid. This paper stops rust during the sea voyage. Then, we put it in a foam box. The foam is custom-cut. The part does not move. Zero movement means zero damage. Finally, we put it in a strong cardboard carton. We tape it with reinforced tape.
We ship globally. We use DHL, FedEx, or sea freight. If you need it fast, we do air freight. If you have time, we do sea freight to save money. We handle the customs paperwork. We declare the value correctly. You won’t get stuck at the port.
