Rotor Clip KG-262SJ Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-262SJ is a spiral-wound internal retaining ring designed for precision retention in bored housings. Manufactured from AISI 302 stainless steel, it provides reliable axial retention of shafts, bearings, and components seated in a 2.625-inch bore. The spiral construction allows the ring to be installed and removed without special pliers in many applications, making it a practical choice for assemblies requiring frequent service access. At 0.093 inches ring thickness and a 0.103-inch groove width, this ring is engineered for tight dimensional control in demanding industrial and mechanical applications. Installation is typically performed by maintenance technicians, millwrights, and mechanical assemblers working on rotating equipment.

This internal retaining ring seats in a machined internal groove within a housing or bore. It is suited for use in pump housings, gearboxes, electric motor end bells, hydraulic cylinders, and similar rotating or reciprocating assemblies where a secure internal shoulder is required to retain a component axially. The ring functions under both static and dynamic load conditions and is appropriate for environments requiring corrosion resistance where stainless steel is specified over carbon steel alternatives.

Key Features

• AISI 302 stainless steel construction offers corrosion resistance for wet or chemically exposed environments
• 2.625-inch bore diameter with 2.801-inch free outer diameter for proper groove engagement
• Groove width of 0.103 inches with a tolerance of 0.000 to 0.005 inches ensures precise fit
• Ring thickness of 0.093 inches with a tolerance of minus 0.003 to plus 0.003 inches
• Thrust load capacity rated at 14,470 pounds at groove safety factor and 30,680 pounds at ring safety factor
• Spiral design allows tool-free or minimal-tool installation in many standard bore configurations

Compatibility

Designed as an OEM-style internal spiral retaining ring for machined bores with a 2.625-inch nominal bore diameter and a groove profile matching 0.103-inch groove width and 0.078-inch groove depth per ROTOR CLIP KG-series specifications.

Installation Notes

Installation should be performed by a qualified millwright, mechanical assembler, or maintenance technician. Verify that the housing groove dimensions match the specified groove width and depth before installation, as an undersized or oversized groove can compromise retention capacity. De-energize all equipment, relieve any hydraulic or pneumatic pressure, and follow applicable lockout/tagout procedures before servicing any assembly containing this ring. Inspect the groove for burrs or damage prior to seating the ring to ensure full contact along the ring circumference.
