Rotor Clip DHO-46ST Pd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP DHO-46ST PD is an internal snap retaining ring designed to secure components within a bored housing or assembly. Manufactured from DIN I7221 I7223 spring steel with a phosphate finish, it provides reliable axial retention in precision-engineered applications. The ring seats in a groove with a 48.5 mm groove diameter, accommodating a 46 mm shaft diameter, with an inside diameter of 49.49 mm. Ring thickness tolerance is held to -0.06 mm and groove diameter tolerance is 0.25 mm. Mechanical assemblers and maintenance technicians install this ring in industrial and trade equipment requiring dependable internal retention without the need for threaded fasteners.

This internal retaining ring is suited for residential and commercial mechanical assemblies where bore-mounted retention is required. Typical applications include pump housings, gearboxes, motors, and similar rotating equipment commonly serviced by HVAC technicians, plumbers, and industrial mechanics. The phosphate finish provides a degree of corrosion resistance appropriate for indoor and controlled-environment installations. This ring meets DIN 472 and ISO 13485:2015 standards, making it appropriate for applications requiring documented material compliance.

Installation Notes

Installation should be performed by a qualified mechanic or technician using proper snap ring pliers sized for internal rings. De-energize and lock out all power to the equipment before disassembly. Ensure the groove is clean and free of burrs before seating the ring to prevent damage to the ring or groove walls. Do not over-expand the ring during installation, as spring steel snap rings can fatigue or fracture if spread beyond their rated deflection.
