Rotor Clip BE-18ST Pa Bowed E Retaining Ring 3/16 in

Product Description

The ROTOR CLIP BE-18ST PA is an external bowed E style retaining ring designed to secure components on shafts with a 3/16 inch (0.1875 inch) shaft diameter and a 0.147 inch groove diameter. Manufactured from SAE 1060-1090 steel with a phosphate finish, this ring provides reliable axial retention in compact assemblies. The bowed profile generates a spring-like thrust load against seated components, reducing looseness and vibration in the installed assembly. With a ring thickness of 0.015 inches and a free outside diameter of 0.335 inches, it fits into tight groove geometries where standard flat retaining rings are not practical. Installed by mechanical assemblers, maintenance technicians, and trade professionals working on motors, pumps, and rotating shaft assemblies.

This retaining ring is suited for use in small-shaft applications across HVAC equipment, pump assemblies, motors, and other rotating machinery where precise axial component retention is required. The three-prong E style design allows installation without special pliers in many configurations, making it practical for field service and production-line assembly alike. Its phosphate finish offers a baseline level of corrosion resistance appropriate for protected indoor mechanical environments.

Key Features

• Bowed profile generates axial thrust load to reduce component play on the shaft
• Three-prong E style design for straightforward installation on 3/16 inch shafts
• SAE 1060-1090 steel construction for consistent hardness and spring characteristics
• Phosphate finish provides basic corrosion resistance for indoor mechanical use
• Groove width of 0.030 inches and groove depth of 0.020 inches for precise fitment
• Meets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards

Compatibility

Designed as an OEM-style external retaining ring for 3/16 inch diameter shafts with a 0.147 inch groove diameter. Confirm groove width, groove depth, and shaft diameter against application specifications before installation.

Installation Notes

Installation should be performed by a qualified mechanical technician or assembler. Always de-energize and lock out equipment before servicing any shaft assembly. E style retaining rings are typically seated by pressing the ring prongs into the groove; verify groove dimensions match ring specifications to avoid improper seating. Inspect the ring for deformation or damage before and after installation, and never reuse a ring that has been removed.
