Rotor Clip DE-3.2ST PDB100 E Style Retaining Ring

Product Description

The ROTOR CLIP DE-3.2ST PDB100 is an external E style retaining ring designed to secure components on small-diameter shafts without the need for threading or welding. Manufactured from 1060/1090 spring steel with a phosphate and oil finish, this ring seats into a 3.2 mm groove diameter and provides reliable axial retention on shafts ranging from 4 to 5 mm in diameter. With a hardness rating of 65-72 HR30N, the ring delivers the spring force and dimensional consistency required in precision assemblies. It is installed by licensed trades and assembly technicians working with small mechanical or electromechanical systems.

This retaining ring is suited for use in compact shaft assemblies found in HVAC equipment, motors, pumps, and other mechanical drive applications. Its metric sizing and compliance with DIN 6799 and SAE 1060-1090 standards make it a practical choice for applications requiring dimensional accuracy and standardized fitment. The phosphate and oil finish provides a baseline level of corrosion resistance for typical indoor service environments.

Key Features

• E style external design seats in a 3.2 mm groove on shafts from 4 to 5 mm in diameter
• 1060/1090 spring steel construction with hardness of 65-72 HR30N for consistent retention force
• Phosphate and oil finish for corrosion resistance in standard service conditions
• Three-prong design provides secure, tool-assisted snap installation
• Meets DIN 6799, SAE 1060-1090, and ISO 13485:2015 standards
• Groove width of 0.64 mm with tight tolerance for precise seating

Compatibility

Designed as an OEM-style replacement or service part for metric shaft assemblies requiring an external E style retaining ring with a 3.2 mm nominal groove diameter and shaft diameter range of 4 to 5 mm, conforming to DIN 6799 specifications.

Installation Notes

Installation and removal should be performed using appropriate external retaining ring pliers to avoid distorting the ring or damaging the groove. Ensure the shaft and groove are clean and free of burrs before seating the ring. Verify groove dimensions match ring specifications prior to installation, as improper fitment can cause ring failure under load. Always relieve system pressure or power down equipment before servicing any shaft assembly containing retaining rings.
