Product Overview of Bushings for Fixtures
The economy series Bushings for Fixtures is a mechanical positioning part that is used in conjunction with a positioning pin to achieve a guiding effect. The shouldered press-fit 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. It is an economy series product from MISUMI.
Product Feature of Bushings for Fixtures
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, outer diameter press-fit dimensiontolerance: M7.
Feature 2: Bushings for Fixtures low cost and stock models can be shipped on the same day.
Feature 3: Bushings for Fixtures auxiliary line can be used for reference during press-fit installation to ensure smooth bushing installation.
Feature 4: material: bearing steel (SUJ2).

Dimensional Drawing of Bushings for Fixtures
The inner diameter 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 ahigh-precision measuring tool (internal micrometer or plug gauge, etc.) for detection.Specifications Overview of Bushings for Fixtures

Example introduction: Bushings for Fixtures positioning pin in pick and place mechanism
Design summary:
① An example of using a swing cylinder to achieve linear and rotary motion through pneumatic drive, and moving a small substrate through a suction cup.
② In 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 Bushings for Fixtures:
The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of positioning pins/shouldered bushings.
