Rotor Clip HO-175ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-175ST ZD is a steel internal snap retaining ring designed to seat in a machined groove inside a bore and axially retain components such as bearings, bushings, and shafts. It is manufactured from SAE 1060-1090 spring steel with a zinc finish for corrosion resistance. The ring fits a 1-3/4 inch bore diameter and measures 1.942 inches free outer diameter with a ring thickness of 0.062 inches. Thrust load capacity reaches 15,580 pounds at the ring safety factor and 8,050 pounds at the groove safety factor. Machinists, millwrights, and maintenance technicians install this type of ring in industrial assemblies, gearboxes, pumps, and mechanical drive systems.

This internal retaining ring is suited for applications requiring precise axial retention within a bored housing or cylinder. The groove dimensions — 0.068 inches wide with a depth of 0.054 inches — must be machined to the specified tolerances before installation. Groove width tolerance is 0.000 to 0.004 inches and groove diameter tolerance is -0.0050 to 0.0050 inches. Rockwell C hardness of 47-52 provides the strength needed for moderate to heavy thrust load environments in both OEM assembly and MRO service work.

Key Features

• 1-3/4 inch bore diameter with 1.942 inch free outer diameter
• Spring steel construction, material grade SAE 1060-1090 (UNS G10600-G10900)
• Zinc finish for corrosion resistance
• Ring thickness of 0.062 inches with tolerance of -0.003 to 0.003 inches
• Thrust load capacity: 15,580 lb ring safety factor / 8,050 lb groove safety factor
• Rockwell C hardness 47-52 for consistent performance under load

Compatibility

Designed for use in any machined internal bore of 1-3/4 inches where the groove conforms to the specified width and depth dimensions. Conforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2016 standards.

Installation Notes

Internal snap rings require snap ring pliers with the correct tip size for the ring diameter — do not substitute general-purpose pliers, as this can distort the ring or cause it to slip during installation. The bore groove must be clean and machined to the specified tolerances before seating the ring. De-energize, de-pressurize, and secure any machinery before disassembly or ring replacement. Inspect the groove for wear or deformation prior to installing a new ring.
