Bushing for locating pin
1.What is bushing for locating pin?
Used in conjunction with a positioning pin, it reduces wear and tear on the machine, ensuring stability of positioning accuracy and service life.
Common materials include SUJ2, SUS440C, SUS304, etc. Various surface treatments are also available, such as black dyeing and electroless nickel plating.
2.Bushing for locating pin type
Type | Introduction | Shape |
---|---|---|
Standard type | The most basic type | Straight column type, with head type, flange type |
Thin-walled type | Wall thickness is more thin, Suitable for use where bushings are closely spaced | Straight column type, with head type |
Anti-loosening type | Fasten the bolts horizontally to Prevents loosening | Straight column type, with head type |
Long Round Hole Type | Long side space can be pinned to absorb clearance errors | With head type, flange type |
Oil free | Suitable for high unplugging frequency applications, and requiring rough guiding | Straight column type, with head type |
3.Shrinkage information of the inner diameter of the jig bushing
The jig bushing shrink as they are pressed in.
The size of the inner diameter shrinkage varies depending on the inner and outer diameter of the bushing, the outer diameter tolerance and the material.
