A set collar is a mechanical part that is fixed to a shaft with a hexagon socket set screw. It is used to fix the position of bearings, sprockets, pulleys, gears, shafts, etc.
Most set collars on the market are metallic, but resin set collars are also commonly available. Since attaching the set collar to the shaft is easy and workable, it is often the first choice when fixing the above-mentioned parts at the time of design, and is used in various situations.
Set collars are general-purpose machine parts and are used in all types of equipment, regardless of the field.
They are mainly used to fix parts such as bearings, sprockets, pulleys, gears, and shafts in the axial direction by fixing the set collar to the shaft.
Also, taking advantage of the features of being able to fix at any position on the shaft, brackets and plates can be slid to any position on the shaft by making it possible to attach brackets and plates to the set collar.
Features of set collars are that they can be easily fixed to the shaft using screws. They are divided into several types according to the different fixing methods:
There are many types of set collars available on the market, but in many cases, product designers design their own set collars. The appropriate method is chosen in consideration of the cost of the parts and the time required.
