The Greenlee Communications model 51339 is a spiral retaining ring manufactured for mechanical assembly applications. The component features specific dimensional characteristics defined by an inner diameter of 0.875 inches, an outer diameter of 1.12 inches, and a thickness of 0.121 inches. It is constructed from steel with a black oxide finish to provide corrosion resistance and friction retention. This hardware item serves as a fastening element within tool assemblies or machinery frames.
Verify the exact dimensional specifications (0.875 x 1.12 x 0.121 inches) against your engineering drawings before ordering. Confirm that the black oxide finish meets your environmental requirements. Ensure the supplier provides traceability documentation if required for your quality management system. Check for any regional export restrictions associated with the manufacturer.
Select this part when a standard spiral retaining ring with these specific dimensions is required. Consider the material compatibility with mating parts to prevent galvanic corrosion. Evaluate the load requirements to ensure the steel construction is sufficient. Compare against alternative finishes if chemical exposure is a factor in the operating environment.
Greenlee Communications specializes in professional-grade tools and accessories for the electrical and communications industries. This component represents their range of precision hardware and replacement parts used in the maintenance and assembly of their proprietary tooling systems. The part number identifies a specific size and configuration within their broader catalog of mechanical fasteners.
Cross-reference with other spiral retaining rings meeting the 0.875 inch bore specification. Verify that substitute parts match the 1.12 inch outer diameter and 0.121 inch thickness exactly. Ensure the material grade and finish are equivalent to maintain performance.
