The TSUBAKI BREU-K series freewheel is a one-way transmission device: it permits rotation in a single direction and locks the opposite direction. It is used to stop backspin, manage intermittent feeds, and safeguard machinery where reverse motion could cause damage or loss of synchronization. MR Industrial Accessories supplies this series, with configuration options to match the code you require.
Reading the BREU-K code helps you specify the right unit. BREU gives the series; the number that follows is the assembly size; the K denotes a keyway on the outer ring. Suffixes such as E1+E2, E2+E3, or E5+E5 identify the mounting accessories included (E1 and E2 are flanges). When you request a freewheel, providing the complete code with these suffixes is the detail that prevents mix-ups.
In US plants, freewheels appear in belt and chain conveyors, bucket elevators, presses, mixers, pumps, and gearboxes. They are also found in bottling equipment, packaging lines, and machine tools that need controlled feed without return. In food, chemical, and cement operations, they serve a safety role: they keep a suspended load or an inclined shaft from rotating backward when power is interrupted.
Selection depends on the torque to be transmitted, rotation speed, operating direction, and mounting type. Sealing matters where dust, water, or frequent washdowns are present. Use the lubricant specified for the working temperature, and align shafts to avoid lateral loads that shorten mechanism life. During installation, confirm that the raceway and locking elements are clean and free of impact damage.
Freewheels come in various brands and configurations. Interchangeability is not automatic: even when two codes look alike, permissible torque, shaft diameter, or fastening type may differ. Compare function and critical dimensions before replacing a unit. If you have the original code or the equipment model, that is the starting point for locating an equivalent.
MR Industrial Accessories supplies the TSUBAKI BREU-K series. For a freewheel for your equipment, send the complete code on WhatsApp—for example, BREU30-K E2+E3 or BREU35-K E1+E2—and we will quote promptly. You can also ask about other configurations in the same series.

Frequently asked questions
- What does the code BREU30-K E2+E3 mean?
- BREU30 is the assembly size, K indicates the keyway on the outer ring, and E2+E3 are the mounting accessories supplied with the unit. For a quote, send the complete code exactly as shown on the nameplate or in the equipment manual.
- How do I determine which freewheel my machine needs?
- You need the torque to be transmitted, speed, shaft diameter, and mounting type. The environment also matters: dust, water, or temperature. With that data and the original code, if available, we can assist. Contact us on WhatsApp and we will help identify the right option.
- Is the TSUBAKI BREU-K series interchangeable with other brands?
- Not always. Even if two freewheels look similar, they may differ in permissible torque, shaft dimensions, or fastening. Interchangeability is assessed case by case by comparing critical specifications. If you send us the original code, we can look for an equivalent within the line we supply.
