Rotor Clip DHO-50ST Pd External Snap Retaining Ring 50mm

Product Description

The ROTOR CLIP DHO-50ST PD is an external snap retaining ring engineered for axial retention on shafts and in bores in mechanical assemblies. Manufactured from spring steel to DIN I7221 and I7223 material grades, this ring delivers reliable holding force in demanding industrial and trade applications. The phosphate finish provides corrosion resistance suitable for general-purpose service environments. Designed for a 50 mm shaft diameter with a groove diameter of 53.01 mm, it installs into a precisely machined groove where it seats flush and resists axial displacement under load. Licensed tradespeople and mechanical assembly technicians are the primary installers.

This retaining ring is suited for use in rotating shaft assemblies, gearboxes, pumps, motors, and similar mechanical components found in HVAC equipment, industrial machinery, and fluid-handling systems. It is a metric-dimensioned fastener conforming to DIN 472, making it appropriate for equipment designed to metric standards. The package quantity is 5 rings per unit, with a minimum order quantity of 1 package.

Key Features

• External snap ring design for shaft-mounted axial retention
• 50 mm shaft diameter with 53.01 mm groove diameter
• Spring steel construction to DIN I7221 and I7223 material grades
• Phosphate finish for general corrosion resistance
• Conforms to DIN 472 fastener standard and ISO 13485:2015
• Metric measurement system for compatibility with DIN-spec equipment

Compatibility

Designed as a DIN 472-compliant external snap retaining ring for 50 mm shafts requiring a 53.01 mm groove diameter. Suitable for any mechanical assembly that specifies a DIN 472 metric external retaining ring in this nominal size.

Installation Notes

Installation requires snap ring pliers sized for external rings of this diameter. Ensure the shaft groove is machined to DIN 472 tolerances before installation. De-energize and lock out all equipment before servicing any assembly containing retaining rings. Do not reuse a ring that has been removed, as spring-back properties may be compromised.
