Rotor Clip DE-4ST Pd B100 E Style Retaining Ring 4mm

Product Description

The ROTOR CLIP DE-4ST PD B100 is an external E style retaining ring engineered for secure axial retention on shafts ranging from 5.00 mm to 7.00 mm in diameter. The ring seats in a 4.00 mm nominal groove diameter and is manufactured from 1060/1090 spring steel, delivering a Rockwell hardness of 65-72 HR30N for reliable performance under repeated loading. A phosphate and oil finish provides baseline corrosion resistance and lubricity during installation. With three prongs and a 0.70 mm ring thickness, this part is a standard metric fastener used in precision assemblies across industrial, mechanical, and OEM applications. Installation and order fulfillment are structured around a minimum order quantity of 100 units.

This retaining ring is suited for metric shaft assemblies where a compact, low-profile E style clip is required to prevent axial movement of components such as gears, bearings, pulleys, or rollers. It is commonly specified in industrial equipment, light machinery, and precision mechanical assemblies where DIN 6799 and SAE 1060-1090 compliance is required. The metric sizing makes it appropriate for imported equipment and globally standardized assemblies. Mechanical assemblers, maintenance technicians, and OEM production lines are the primary installers of this fastener type.

Key Features

• E style external retaining ring for shafts from 5.00 mm to 7.00 mm diameter
• 4.00 mm nominal groove diameter with tight groove diameter tolerance of -0.0750 to 0.0750 mm
• 1060/1090 spring steel construction with 65-72 HR30N hardness for durability under load
• Phosphate and oil finish for corrosion resistance and ease of installation
• Three-prong design for positive retention and easy tool-assisted removal
• Meets DIN 6799, SAE 1060-1090, and ISO 13485.2015 standards

Compatibility

Designed as a standard DIN 6799 external E style retaining ring for metric shaft assemblies requiring a 4.00 mm groove diameter. Suitable for shafts with a minimum diameter of 5.00 mm and a maximum diameter of 7.00 mm where a phosphate-finish spring steel clip meets design requirements.

Installation Notes

This retaining ring is installed by mechanical assemblers and maintenance technicians using external snap ring pliers or E ring applicator tools sized for the 4.00 mm groove. Ensure the shaft groove is clean and free of burrs before seating the ring to avoid damage to the ring thickness or groove width tolerances. Always verify the groove dimensions match the specified tolerances before installation. Do not over-flex the ring during installation, as spring steel at this hardness range can crack if bent beyond its design deflection.
