    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.

    ⑥Martensitic stainless steel-Quenching hardness 50～55HRCE-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.
    Precautions
    ①Dimensional tolerance and fit parameter table For details, click Dimensional Tolerance Fit Table
    ②Reference table for common dimensions without indicated tolerance (medium accuracy m) For details, click Table of Dimensions Without Indicated Tolerance
    ③Reference value for thread mounting torque The tightening torque (reference value) is the strength class (8.8) in the technical data Torque Tightening Reference Table, and the tightening state lasts for more than 24 hours. Not applicable when using locking agents or spring washers.
    Example of Use
    Example of Use for Straight Sphere Locating Pins  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.
