Positioning Pin - Eccentric

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. The eccentric type positioning pin is suitable for situations where the positions of the mounting hole and the positioning hole are different, and is easy to install.

Type	Material	Surface Treatment	Hardness
Standard
E-JPEA	SKS3 Equivalent	-	Quenching hardness 60 to 63HRC
E-GJPEA	SKS3 Equivalent	Hard Chrome Plated	Quenching Hardness 50–55HRC / Coating Hardness 750HV–
E-CJPEA	SUS440C Equivalent	-	Quenching hardness 50 to 55HRC
E-SJPEA	SUS304 Equivalent	-	-

If there are requirements for rust prevention, give priority to products with hard chrome plating, electroless nickel plating surface treatment, or those made of stainless steel.

Feature: Positioning pin used when the hole positions of the installation part and the positioning part are different.
1. Simple eccentric adjustment is possible;
2. Material options: Iron (alloy tool steel or bearing steel); Stainless steel (austenitic stainless steel, martensitic stainless steel),
3. With surface hard chrome plating specifications, effectively ensuring surface hardness and rust prevention.
