What Is a Set Collar?
A set collar is a mechanical part that is fixed to a shaft with a hexagon socket set screw, etc. It is used to fix the position of bearings, sprockets, pulleys, gears, shafts, etc.
Most set collar 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.
Uses of Set Collars
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
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.
- Standard type
This is a standard type of set collars. The inside diameter has a precision hole corresponding to the shaft diameter, and in most cases, they are fixed to the shaft with a hexagon socket head cap screw. Since they are fixed with a hexagon socket bolt, the shaft will be scratched. - Slit type
This type has a slit in the collar and looks C-shaped. One side of the slit has a tap, and the other side has a hole and a counterbore on the same axis. Compared to the standard type, this type can be tightened more strongly and does not damage the shaft. - Split type
This type is set collars that are fixed to the shaft by screwing two semicircular parts that look like a collar cut in two. Features of this type are that it is not necessary to insert the collar from the end face of the shaft since it is completely separated into two parts, and it can be directly assembled to the desired location.
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.
