Rotor Clip DSH-15ST Pd External Retaining Ring 15mm

Product Description

The ROTOR CLIP DSH-15ST PD is a metric external retaining ring designed for shaft-groove retention in mechanical assemblies. Made from spring steel with a phosphate finish, this ring seats into a precision groove on the outside diameter of a shaft to prevent axial movement of adjacent components. It conforms to DIN 471 and ISO 13485:2015 standards, confirming dimensional and quality compliance for industrial and medical-adjacent applications. With a nominal shaft diameter of 15 mm, a groove diameter of 14.3 mm, and a ring thickness of 1.00 mm, this part is suited for close-tolerance assemblies where consistent retention force and compact geometry are required. Machinists, maintenance technicians, and mechanical assemblers install this type of ring using standard external snap-ring pliers.

This external retaining ring is intended for use on 15 mm shafts in mechanical, industrial, and equipment-assembly applications. It is commonly found in gearboxes, motors, pumps, and similar rotating or reciprocating machinery where axial retention of bearings, collars, or housings is needed. The phosphate finish provides a base level of corrosion resistance suitable for indoor and controlled-environment service. Applications conforming to DIN 471 dimensional standards will find this ring a direct-fit solution in metric shaft configurations.

Key Features

• Conforms to DIN 471 and ISO 13485:2015 dimensional and quality standards
• Spring steel construction provides reliable retention force and elasticity for repeated installation cycles
• Phosphate finish offers base corrosion resistance for controlled-environment service
• Groove diameter of 14.3 mm with a tolerance of -0.11 mm for close-tolerance shaft applications
• Ring thickness of 1.00 mm with a tolerance of -0.06 mm for precise groove seating
• Metric system dimensioning throughout for compatibility with DIN-standard assemblies

Compatibility

Designed as a DIN 471-compliant external retaining ring for 15 mm nominal diameter shafts with a 14.3 mm groove diameter. Suitable for any mechanical assembly specifying a DIN 471 ring at this nominal size.

Installation Notes

Install and remove external retaining rings using external snap-ring pliers sized for this ring diameter to avoid distortion or over-expansion of the ring. De-energize and lock out any machinery before servicing shaft components. Inspect the shaft groove for burrs or damage that could prevent proper seating before installation. Do not re-use rings that have been visibly deformed or over-expanded during removal.
