Rotor Clip KG-50SJ Internal Spiral Retaining Ring 0.5 in

Product Description

The ROTOR CLIP KG-50SJ is a stainless steel internal spiral retaining ring designed to secure components within a bored housing or shaft assembly. Manufactured from AISI 302 stainless steel and conforming to AMS-5866 and ISO 13485.2016 standards, this ring installs into a machined internal groove to retain bearings, pins, and similar components against axial movement. With a 0.5-inch bore diameter, a free outside diameter of 0.538 inches, and a ring thickness of 0.035 inches, the KG-50SJ delivers precise fitment in tight-tolerance assemblies. It is installed by maintenance technicians and mechanical assemblers in industrial and commercial equipment applications.

This internal spiral retaining ring is suited for applications requiring corrosion resistance, such as fluid-handling equipment, food processing machinery, and medical device assemblies. Its spiral design allows for tool-free or low-force installation by coiling into the groove without the need for specialized snap ring pliers, making it a practical choice in high-volume assembly operations or field service environments where access is limited. The groove width of 0.039 inches and groove depth of 0.015 inches define the machined bore specification required for proper installation.

Key Features

• AISI 302 stainless steel construction provides corrosion resistance for wet, chemical, or hygienic environments
• Spiral ring design allows installation and removal without standard snap ring pliers
• Thrust load capacity of 2,530 pounds at ring safety factor and 530 pounds at groove safety factor
• Tight groove width tolerance of 0.000 to 0.003 inches for precise axial retention
• Conforms to AMS-5866 and ISO 13485.2016 standards
• Ring thickness tolerance held to plus or minus 0.002 inches for consistent seating

Compatibility

Designed as an OEM-style internal retaining ring for bored housings requiring a 0.5-inch bore diameter with a groove width of 0.039 inches and groove depth of 0.015 inches. Confirm bore and groove dimensions against engineering drawings before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with retaining ring applications and precision assembly practices. Ensure the bore groove dimensions match the specified groove width and depth before installation to prevent ring failure under load. De-energize and lock out all equipment before disassembly or ring replacement. Avoid over-stressing the ring during installation, as permanent deformation will reduce thrust load capacity.
