Product Overview
The fixture bushing is a mechanical positioning part that is used in conjunction with a positioning pin to achieve a guiding effect, in which the custom dimension, straight type offers a wide range of dimensions, easy to install. And it can effectively prevent the rapid wear of the workpiece.
Dimensional Drawing
Dimensional Drawing
The p7 type has a larger inner diameter shrinkage rate compared to the m7 type, so be careful when machining holes. (See Precautions for the inner diameter change after press-fit)

If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating.
The I.D. tolerance of bushing is high. If a vernier caliper is used for detection, the measurement result will be too small. It is recommended to use a high-precision measuring tool (internal micrometer or plug gauge, etc.) for detection.

Product Features
Features and usage outline of fixture bushing product Jig Bushings Straight Standard
Feature 1: straight, custom dimension type, press-fit installation, the tolerance of the O.D. press-fit dimension can be specified: p7, m7.
Feature 2: custom inner diameter, I.D. Dimension specified in 0.01mm increments, wide selection range
Feature 3: electroless nickel plated type can effectively prevent rust.
Feature 4: optional material: iron (alloy tool steel or bearing steel); austenitic stainless steel (martensitic stainless steel), suitable for locating pins made of various materials.
Precautions
①Dimensional tolerance and fit parameter table For details, click Dimensional Tolerance Fit Table
②Change in inner diameter of the fixture bushing during press-fit
■Change in inner diameter of the fixture bushing during press-fit
The fixture bushing shrinks when press-fitted.
The shrinkage rate varies depending on material of mounting part and D dimension tolerance of bushing.

Example of Use
Example of using bushing for positioning pin and example of fixture
Example introduction: Positioning application of the relative position of the upper and lower plates of the fixture
Function description:
  The position accuracy of the upper and lower plates of the fixture is ensured by the coordinated use of positioning pins and bushings.
Advantages of fixture bushings:
  ①The bushing hardness is slightly lower than the positioning pin, which effectively protects the positioning pin from rapid wear and ensures the positioning accuracy.
  ②The bushing is easy to replace when it wears out, effectively protecting the bottom plate or workpiece from damage.
