Tsubaki BR-HT freewheels are power transmission mechanisms that allow rotation in one direction and lock movement in the opposite direction. They are used as backstops or to engage and disengage shafts according to relative speed, and are common in equipment where a load must not reverse or movements must be synchronized. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, with technical advice to choose the right model.

The BR-HT series designation is read in blocks. The letters BR identify the freewheel family, the number that follows indicates the body size, and the HT suffix indicates the series variant. Then comes the letter R with a second number, which corresponds to the diameter or the type of shaft the assembly works with. For example, in BR30HT-R51B the 30 defines the size and the 51 the shaft; in BR220HT-R290B, the 220 and the 290. The final letter B distinguishes the mounting design. The complete part number unambiguously identifies each combination.

In Argentine industry these freewheels appear in inclined conveyor belts, bucket elevators, mills, mixers and material handling equipment where a load must not reverse. They are also mounted in machine tool drives, pumps and gear reducers that need automatic disengagement. As part of the power transmission line, they work alongside chains, pulleys and couplings in food, cement, mining and bulk process plants.

To select a freewheel, review the required direction of rotation, the shaft diameter and tolerance, and the torque the mechanism must transmit. Mounting requires clean surfaces, correct alignment between shaft and housing, and adequate lubrication according to the working environment. In applications with dust, humidity or frequent washdowns, evaluate the sealing and the type of grease. Forced or misaligned mounting shortens the life of the mechanism and can cause noise or premature wear.

Freewheels are interchanged between manufacturers by part number, shaft dimensions and torque capacity, not only by the commercial designation. Each brand uses its own nomenclature, so two references with similar numbers may not be equivalent. To replace a unit, compare the original part number, the shaft and housing dimensions and the direction of operation. If you have doubts, send us a photo of the nameplate or the mechanism and we will verify it with you.
