Will the positioning pin rust? If so, are there any measures to prevent?

Positioning pin products without surface treatment will rust. It is recommended to regularly apply antirust oil for maintenance or purchase positioning pins with surface treatment, which can prevent rust in normal atmospheric environments.

Why does the positioning pin neck have a relief groove?

Because of high coaxiality, the neck also needs to be grinded. The neck grinding process requires a relief groove to ensure that the positioning pin does not produce R angle.

Can shapes and sizes other than those listed in the catalog be customized?

Yes, they can be customized. However, please show the drawings when customizing and there are certain requirements on the quantity. Please consult cs@misumi.sh.cn for details

Where are the positioning pins made?

In principle, they are made in China. Some products with high accuracy and complex surface treatment process are made in Japan.

In which case there is no center hole?

Material is SUS304, and there is no center hole when it can meet the accuracy requirements in the milling state. Or when there is a large quantity in mass production.

Why does the positioning pin have center hole?

The final machining stage is centerless grinding. There is a need for center hole positioning, so center hole is drilled for centerless grinding.

Product of Locating Pins Overview

The positioning Locating Pins is used for the spatial positioning in the directions of X and Y axes, mainly using the workpiece hole as the positioning benchmark or used in conjunction with bushings, in which the straight rod cone head type is simple in shape, easy to install, widely used, and adopts materials with high hardness and difficult to break. On the basis of ensuring the original accuracy, it has the characteristics of low price and fast delivery time.

Product of Locating Pins Feature

Usage outline of cheap and preferential straight rod tapered angle type positioning pins Locating Pins

Locating Pins Feature 1: Standard type with cone head. Rod diameter tolerance that can be specified for the press-fit type: m6, g6.
Locating Pins Feature 2: The material is SUS440C, which has both heat treatment hardness and certain toughness, which is suitable for various working conditions.
Locating Pins Feature 3: The installation space is small, and the straight rod cone head type positioning pin is more suitable for simple lateral positioning.
Locating Pins Feature 4: The price of economy series straight rod cone head positioning pin is more affordable than the non-economy series, which is suitable for mass purchase.

Locating Pins Type		Material	Hardness
D dimension m6	D dimension g6
CUM	CUG	Equivalent to 9Cr18 (SUS440C)	Quenching hardness 55 to 60HRC

SUS440C hardness is different from the equivalent of SUS440C (50 to 55 HRC).

If there are requirements for rust prevention, give priority to other straight rod tapered products of Locating Pins with hard chrome plating and stainless steel SUS3 series.

Example of Locating Pins Use

Example introduction: straight rod cone head positioning Locating Pins and shouldered bushing in pick and place mechanism
Design summary:
① An example of Locating Pins 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 fixture bushing:
The axial structure of the swing cylinder can ensure positioning accuracy while saving space through the coordination of positioning pins/shouldered bushings.
