Rotor Clip HO-250SS Internal Snap Retaining Ring 2.5 in

Product Description

The ROTOR CLIP HO-250SS is a heavy-duty internal snap retaining ring designed to secure components within a bored housing or assembly. Manufactured from 15-7 stainless steel (Grade 632), this ring seats into a precision-cut groove inside a 2.5-inch bore diameter housing. With a Rockwell C hardness rating of 44 to 51 and a thrust load capacity of 15,650 pounds at the groove safety factor, this ring is built for demanding industrial and mechanical applications. Ring thickness is 0.078 inches, and the free outer diameter measures 2.78 inches. A licensed machinist or maintenance technician typically installs this part during assembly or overhaul work where reliable axial retention is required.

This internal retaining ring is suited for use in mechanical assemblies, pumps, motors, gearboxes, and similar equipment requiring positive component retention within a bore. Its stainless steel construction makes it appropriate for environments with exposure to moisture, mild corrosives, or elevated temperatures where carbon steel rings would degrade. The groove width of 0.086 inches and groove depth of 0.074 inches correspond to standard internal groove dimensions for a 2.5-inch bore application. Installers should verify groove dimensions against the specified tolerances before installation.

Key Features

• 2.5-inch bore diameter internal snap ring for housing-groove installation
• 15-7 stainless steel (Grade 632) construction for corrosion resistance and high strength
• Rockwell C hardness of 44 to 51 for wear and deformation resistance
• Thrust load capacity of 15,650 pounds (groove safety factor) and 28,014 pounds (ring safety factor)
• Groove width of 0.086 inches with tolerance of 0.000 to 0.005 inches
• Meets AMS-5529, UNS S15700, and ISO 13485:2016 standards

Compatibility

Designed as an OEM-style internal retaining ring for mechanical assemblies with a 2.5-inch bore diameter groove conforming to standard internal snap ring groove dimensions.

Installation Notes

Internal snap retaining rings are installed by machinists, millwrights, or mechanical technicians using internal snap ring pliers sized for the bore diameter. Always de-energize and lock out the equipment before disassembly or ring installation. Confirm groove width, groove depth, and bore diameter match the ring specifications before installation to ensure full seating and rated load performance. Do not over-compress the ring during installation, as permanent deformation can reduce thrust load capacity.
