Will the fixture bushing rust?

Products without surface treatment will rust. It is recommended to regularly apply antirust oil for maintenance or choose products with surface treatment (no-electro nickel plated), which can prevent rust in normal atmospheric environments. No-electro nickel plated surface can effectively prevent rust.

What tools are suitable for measuring the inner diameter of the fixture bushing?

If the inner diameter tolerance of the fixture bushing is within 0.02mm, common vernier calipers and other measuring tools with general accuracy are not suitable. It is recommended to use a high accuracy plug gauge or an internal micrometer for measurement.

Will the inner diameter of the fixture bushing become smaller after installation?

It will become smaller, and p6 will shrink more than m6 and m7 after installation, so please pay attention during hole machining. For detailed change values, please refer to the precautions: change in inner diameter of the fixture bushing during press-fit.

What are the options for fixture bushing outer diameter tolerance?

Optional tolerances for the outer diameter of fixture bushing: m6, p6, g7, m7. Basically it can meet the needs of installation and positioning under general conditions.

What positioning pins are commonly used together with fixture bushings?

The fixture bushing is of basic shape, which is usually suitable for supporting positioning pins, checking insertion pins for fixtures, etc.

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 work piece, effectively controlling the installation position. And it can effectively prevent the rapid wear of the work piece. It is an economy series product by MISUMI.

Product Feature of Bushings for Fixtures

Features and usage outline of Bushings for Fixtures product Jig Bushings Shoulder Standard

Feature 1: Bushing for Fixtures straight press-fit type, press-fit installation, outer diameter press-fit dimension tolerance: M7.
Feature 2: Bushing for Fixtures at low cost and stock models can be shipped on the same day.
Feature 3: Bushing for Fixtures auxiliary line can be used for reference during press-fit installation to ensure smooth bushing installation.

Feature 5: Bushing for Fixture F7 inner diameter, which allows for easier and faster coordination with positioning pins.

Dimensional Drawing of Bushings for Fixtures

Fixture bushing dimensional drawing and diagram

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 a high-precision measuring tool (internal micrometer or plug gauge, etc.) for detection.

Example Use of Bushings for Fixtures

Example of using bushing for positioning pin and example of fixture

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 a 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.
