Caution

Product Description

Product Overview

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

Material No.	Material	Surface Treatment	Hardness	Type
Material No.	Material	Surface Treatment	Hardness	Tapped
①	Alloy tool steel or bearing steel	-	Quenching hardness 60～63HRC	E-LPSQTA
②	Alloy tool steel or bearing steel	Hard Chrome Plated	Quenching hardness 50～55HRC Plating hardness 750HV～	E-GLPSQTA
③	Alloy tool steel or bearing steel	-	-	E-BLPSQTA
④	Austenitic stainless steel	-	-	E-SLPSQTA
⑤	Austenitic stainless steel	Hard Chrome Plated	Plating hardness 750HV～	E-HLPSQTA
⑥	Martensitic stainless steel	-	Quenching hardness 50～55HRC	E-CLPSQTA

Martensitic stainless steel products have an identification groove on D part.

Since there is a center hole, the spheric part is almost invisible when the D dimension is small.

If there are requirements on rust prevention, give priority to the hard-chrome plated or austenitic stainless steel products.

Product Features

Usage outline of straight sphere locating 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: Multiple mounting methods, including the press-fit type and tapped type.
Feature 3: Optional material: iron (alloy tool steel or bearing steel); austenitic stainless steel, martensitic stainless steel, suitable for positioning of various 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 straight sphere locating pin is more suitable for simple lateral positioning in a small installation space.

Example of Use

Example introduction: Positioning of plastic frame
①The outer plastic frame, with some portions being thin-walled, is prone to collision and friction with the positioning parts when located on the tooling plate, resulting in damage, deformation, or even breakage of the product.
②The spherical shape of the spherical locating pin ensures that the circuit frame slides smoothly into the specified position without damaging the product.
③The materials of plastic frame products contain fiberglass, and hard-chrome plated spherical locating pins can ensure good abrasion resistance, increasing the service life.
