Part Number

Configured Part Number is shown.

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 shouldered, standard type is widely used, and the shoulder contacts the workpiece, effectively controlling the installation position. And it can effectively prevent the rapid wear of the workpiece.
Dimensional Drawing
Fixture bushing dimensional drawing and diagram
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)

Product Features
Features and usage outline of fixture bushing product Jig Bushings Shoulder Standard
Feature 1: fixture bushing, shouldered press-fit type, can support the body through the shoulder, and is suitable for applications where it is difficult to adjust the hole depth, press-fit installation, the tolerance of the O.D. press-fit dimension can be specified: p7, m7.
Feature 2: low cost and a rich variety of types, stock models can be shipped on the same day.
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).
Feature 5: Some models are ordered in a large quantity of 500 pcs, and can be shipped within 7 days, For details, consult by CS@misumi.sh.cn.
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: shouldered bushing for positioning pin in pick and place mechanism
Design summary:
  ①An example of using a swing cylinder to achieve linear and rotary motion through pneumatic drive, and moving a small substrate through a suction cup.
  ②In the case of a long pin, if the air vent is not provided, the pin and bushing are not easy to pull out. It is necessary to provide a air vent on the bushing side or the positioning pin side.
Intended use of fixture bushing:
  The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of positioning pins/shouldered bushings.
