Caution

Product Description

Product Overview

The positioning pin 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 shank spherical type is easy to install, and the spherical part ensures smooth positioning and protects the workpiece.

⑤	SUS304 Equivalent	Hard Chrome Plated	Coating hardness 750HV or more	E-HLPSQA
⑥	SUS440C Equivalent	-	Quenching hardness 50 to 55HRC	E-CLPSQA

The introduction section of the martensitic stainless steel features an identification groove.

Because it has a center hole, the spherical part is almost invisible when the D dimension is small.

If there are requirements for rust prevention, give priority to products with hard chrome plating or made of austenitic stainless steel.

Product Features

Usage outline of straight rod spherical type positioning pins Locating Pins

Feature 1: Standard type with spherical head. Rod diameter tolerance that can be specified for the press-fit type: m7, p7, g7, h7.
Feature 2: Available in press-fit and internal thread types, offering various installation methods.
Feature 3: Optional Material: Iron (alloy tool steel or bearing steel); Stainless Steel (austenitic stainless steel, martensitic stainless steel), suitable for positioning of a variety of workpieces.
Feature 4: Hard chrome plated surface, effectively ensuring surface hardness and antirust.
Feature 5: The lead-in part of the sphere can make the workpiece lead in by sliding sideways, without damage.
Feature 6: The installation space is small, and the straight rod spherical type positioning pin is more suitable for simple lateral positioning.

Example of Use

Example of Using Spherical Positioning Straight Rod

Case Introduction: Positioning of Plastic Frame
(1) The outer frame of the plastic has some areas with thinner wall thickness. When positioning on the tooling plate, it is easy for the product to rub against the positioning parts, which can cause scratches, deformation, or even breakage.
(2) The spherical shape of the spherical positioning pin allows the circuit frame to slide smoothly into the designated position without damaging the product.
(3) The plastic frame products contain glass fiber in the material, and the spherical positioning pins with hard chrome plating ensure excellent wear resistance and extend the service life.
