Set Collars
1.What is set collars
The set collars is a type of shaft fitting that helps to fix and limit the position of cylindrical objects.
Common materials include S45C, SUS304, aluminum alloy, etc.; various surface treatments are also available, such as black dyeing, electroless nickel plating, anodic treatment, etc.
Type | Introduction |
---|---|
Standard Type | The most commonly used type is the one in which the shaft is held in place with stop screws. |
Open Seam Type | Better tightness and less damage to the shaft. |
Separate Type | Not easy to hurt the shaft, easy to assemble, easy to disassemble. |
Cutting Type | The cutting surface can be used for optical fiber, etc. |
Wedge Type | The special shape is designed to facilitate quick and frequent disassembly and adjustment. (Handle can be attached) |
Hinge Type | It is convenient for loading and unloading guide shafts in places where operation is difficult. |
Other | Including inner thread type, quick mount type, keyway type, etc. |
2.Set Collars Application
Common Use Areas
Can be used for blocking, positioning, and pressed pulleys, such as standard, open seam, separate, and wedge type (with handle)

Bearing fixed
Can be used to fix the inner wheel of the bearing, such as standard type, open seam type
Sensors fixed
Available for sensor mounts such as standard, open seam, separate, wedge (with handle)

Buffer
It can avoid the sound generated by metal parts colliding with each other, such as open seam type and separate type.
Other parts installation
Various types of mounting holes for base plate and other parts, such as standard, open seam, separated type

3.Common types of chasing processing
Type | Function |
---|---|
Countersunk head hole | Keep the screws head will not be higher than the fixed surface. As a mounting hole, it can be used on a flat surface or a support frame. |
outer screw thread | Embedded screw threads to improve the mechanical strength of the screw section. |
Expanded inner diameter | The inner diameter is increased according to the demand of fixed ring. |
Tapping hole | With screw thread. As a mounting hole, it can be used on a flat surface or a support frame. |
D-cut | The sensor support bracket can be simply installed using the mounting holes on the cut surface. |
Keyway | Machining of grooves to match the key for mounting the key for transferring the torsional moment. |
4.Related applications
In order to prevent slippage and cause instability in use, the use of retaining rings can be found in various industrial and automatic equipment units.
besides used to fix, it can also used to trigger the start of other components.
Applications | For example |
---|---|
Automotive Related | Sensors, safety devices, etc. |
Transmission Related | Gear sets, belts, chain drives, etc. |
Industrial Related | Machines and instruments, etc. |
