Rotor Clip DE-7ST Pd B100 E-style Retaining Ring 7mm

Product Description

The ROTOR CLIP DE-7ST PD B100 is an external E-style retaining ring designed to seat in a groove on a shaft and provide a positive stop against axial movement of assembled components. It is manufactured from 1060-1090 spring steel and carries a phosphate and oil finish for corrosion resistance and lubricity. With a 7 mm groove diameter and a shaft diameter range of 8 to 11 mm, this ring delivers reliable retention across a moderate range of shaft sizes. Ring thickness is 0.90 mm and groove width is 0.94 mm. The three-prong E-style profile allows installation without special pliers on many applications, though snap-ring pliers remain standard practice. Machinists, assembly technicians, and mechanical maintenance trades install these rings in production and field-service environments.

This retaining ring is suited for light to medium-duty shaft retention in mechanical assemblies including motors, gearboxes, pumps, and rotating equipment where an external groove is machined into the shaft. The metric 7 mm nominal sizing makes it appropriate for metric-dimensioned components. It meets DIN 6799 and SAE 1060-1090 standards and is also referenced under ISO 13485:2015. The phosphate and oil finish reduces friction during assembly and provides a base layer of corrosion protection for indoor and controlled-environment applications. Minimum order quantity is 100 pieces; this listing represents a single package quantity of 1.

Key Features

• External E-style three-prong design allows tool-free or snap-ring-plier installation on 8 to 11 mm shafts
• 1060-1090 spring steel construction with hardness of 65-72 HR30N for reliable retention under load
• Phosphate and oil finish provides corrosion resistance and reduces assembly friction
• Groove diameter tolerance of -0.09 to +0.09 mm supports precise fitment in machined grooves
• Meets DIN 6799, SAE 1060-1090, and ISO 13485:2015 standards
• Metric nominal sizing for use with metric-dimensioned shafts and components

Compatibility

Designed as a DIN 6799-compliant external E-style retaining ring for metric shafts with a 7 mm groove diameter and shaft diameters from 8 to 11 mm. Compatible with assemblies requiring a 0.94 mm groove width and 0.90 mm ring thickness per DIN 6799 and SAE 1060-1090 specifications.

Installation Notes

Power down and de-energize any equipment before servicing shaft assemblies. Use appropriately sized snap-ring pliers or E-ring installation tools to seat the ring fully into the groove without over-stressing the prongs. Inspect the shaft groove for burrs or damage before installation, as groove defects can cause improper seating or ring failure under load. Follow applicable machinery safety standards and equipment manufacturer guidelines when replacing retaining rings in rotating assemblies.
