Caution

Product Description

Product Overview

The economy fixture bushing is a mechanical positioning component used together with a locating pin to provide guidance. The shoulder press-fit type is widely used, with the shoulder contacting the workpiece to effectively control the installation position.
It can also effectively prevent rapid wear of the workpiece and is part of MISUMI's economy product line.

Dimensional Drawing

The inner diameter tolerance of the bushing is highly precise. If a vernier caliper is used for measurement, the result may be smaller than the actual value. It is recommended to use high-precision measuring instruments (such as an inside micrometer or plug gauge) for inspection.

Compared to the m7 type, the p7 type has greater inner diameter shrinkage, so please pay attention during hole machining.

Product Features

Feature 1: The shoulder press-fit type fixture bushing can support the main body through its shoulder, making it suitable for applications where hole depth is difficult to adjust. It is installed by press-fitting, with an outer diameter press-fit tolerance of m7.
Feature 2: The economy bushings offer a higher cost-performance ratio, and in-stock models can be shipped the same day.
Jig Bushing Product Features

Feature 3: Equipped with a reference line, which can be used to align the horizontal position during press-fit installation to ensure smooth installation of the bushing.
Jig Bushing Product Features

Feature 4: Material: Bearing steel (SUJ2).
Feature 5: The inner diameter tolerance is F7, which increases the clearance with the locating pin, making assembly and fitting quicker.
