Rotor Clip SH-262ST Zd External Retaining Ring 2-5/8 in

Product Description

The ROTOR CLIP SH-262ST ZD is an external retaining ring designed for use on shafts with a 2-5/8 inch (2.625 inch decimal) diameter. It seats in a machined external groove to axially retain components such as bearings, gears, and pulleys without threaded fasteners. Manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating for corrosion resistance, this ring meets SAE 1060-1090 and UNS G10600-G10900 standards. Hardness is rated at 47-52 HRC. Machinists, millwrights, and mechanical technicians install this type of ring during assembly or field repair of rotating equipment.

This external retaining ring is suited for industrial and mechanical assemblies where a 2-5/8 inch shaft is present and a groove has been machined to the specified dimensions: 2.481 inches groove diameter with a groove width of 0.086 inches and a groove depth of 0.072 inches. It is applicable in HVAC blower shaft assemblies, pump shaft retention, gearbox assemblies, and similar rotating-equipment applications where a positive axial stop is required without welding or threading.

Compatibility

Designed for use on external-groove shafts with a 2-5/8 inch diameter where the groove is machined to 2.481 inches diameter, 0.086 inches wide, and 0.072 inches deep per SAE 1060-1090 retaining ring specifications.

Installation Notes

External retaining rings of this size typically require heavy-duty external snap-ring pliers sized for the ring's lug holes. Ensure the shaft groove is clean and dimensionally correct before installation; a damaged or undersized groove can cause the ring to seat improperly and fail under load. Relieve all axial and rotational loads on the assembly before removing or installing the ring. Follow applicable ANSI B18 or OEM service procedures for the equipment being serviced.
