A metal collar is a metal ring-shaped component that, like a spacer, is fastened to a drive shaft or shaft with a hexagon socket head cap bolt. Some collars are simply inserted into the drive shaft or shaft without tightening with bolts.
The differences between collars and spacers are as follows:
Generally, "set collars" are also sometimes used synonymously.
There are integral type and two-part separate type, and they are used according to the place of use, Uses of, workability, etc.
The main uses of metal collars are used to secure parts such as bearings, sprockets, pulleys, gears, and shafts against the shaft direction by fixing the metal collars to the shaft.
Since metal collars can be secured in any position relative to the shaft, brackets and plates can be made attachable to the metal collars, allowing the bracket or plate to slide and be secured in any position on the shaft.
They may also be used to fit onto a drive shaft or axis without bolting it down, to keep a constant spacing between parts by the height of the metal collars.
Features of metal collars are that they can be easily fastened to a shaft using bolts. They are divided into several types depending on the fixing method.
The inner diameter of the metal collars has precision hole corresponding to the shaft diameter and is secured to the shaft with a hexagon socket head cap screw. Since the shaft is fixed with a hexagon socket bolt, the shaft will be scratched.
The metal collars have a slit and are C-shaped. One side separated by the slit has a tap, and the other has a hole and a washer on the same axis. Tightening this part with a hexagon socket head cap bolt tightens the inside diameter part and fixes it to the shaft.
The metal collars are split into two parts, each of which is fastened with a hexagon socket head cap screw.
Carbon steel (S45C) and stainless steel (SUS304) are used as materials. Aluminum steel (A2017) is also used for insertion only, instead of fastening with standard type hexagon socket head cap screws.
