Rotor Clip DSH-11ST Pd External Retaining Ring 11mm

Product Description

The ROTOR CLIP DSH-11ST PD is a metric external retaining ring designed for use on 11 mm diameter shafts. Manufactured from spring steel with a phosphate finish, this ring seats into a 10.5 mm groove diameter to secure components axially on a shaft without the need for threading, welding, or additional fasteners. With a ring thickness of 1.00 mm and a groove depth of 0.25 mm, the DSH-11ST PD conforms to DIN 471 standards and is also manufactured in alignment with ISO 13485:2015 quality management requirements. It is a compact, single-piece fastening solution used by mechanical assemblers and maintenance technicians across industrial and mechanical applications.

This external retaining ring is suited for light- to medium-duty shaft retention in assemblies where a precise metric groove profile is required. The DIN 471 standard profile makes it a direct fit in applications engineered to metric specifications. Typical use cases include motor shaft assemblies, gear train components, hydraulic actuator assemblies, and similar rotating or reciprocating machinery. The phosphate finish provides a baseline level of corrosion resistance appropriate for indoor or protected environments. Sold individually, with a minimum order quantity of 25 units.

Key Features

• DIN 471 standard external retaining ring profile for 11 mm shafts
• Spring steel construction provides reliable radial retention force
• Phosphate finish offers baseline corrosion resistance for protected environments
• Groove diameter tolerance of -0.11 mm ensures consistent seating in precision-machined grooves
• Ring thickness tolerance of -0.06 mm supports tight assembly clearances
• Manufactured under ISO 13485:2015 quality management system

Compatibility

Designed for use in metric shaft assemblies with an 11 mm shaft diameter and a groove machined to DIN 471 specifications, including a 10.5 mm groove diameter, 0.25 mm groove depth, and 1.10 mm groove width.

Installation Notes

Installation and removal of external retaining rings requires appropriately sized external snap ring pliers to avoid ring distortion or loss of spring temper. Always power down or de-energize the host equipment and relieve any mechanical load before servicing shaft components. Rings should not be over-spread during installation, as excessive deflection can permanently deform the spring steel and compromise retention force. Verify groove dimensions against DIN 471 tolerances before installation to ensure proper seating.
