Rotor Clip SH-18BC B100 External Retaining Ring 3/16 in

Product Description

The ROTOR CLIP SH-18BC B100 is an external retaining ring designed for use on 3/16-inch (0.1875-inch) diameter shafts. It seats into a precision-machined groove and provides axial retention of components without threading or welding. Manufactured from beryllium copper to ASTM B197 and UNC C17200 standards, the ring carries a zinc finish for added surface protection. At 0.015 inches thick with a 0.018-inch groove width and a 0.006-inch groove depth, it is sized for compact assemblies where tight tolerances are critical. Licensed technicians and mechanical assemblers install these rings in production and field-repair applications.

This retaining ring is suited for light-duty shaft assemblies across industrial, mechanical, and trade-equipment applications. Its small shaft diameter makes it common in instrumentation, small-motor assemblies, pumps, and actuator mechanisms. The ring installs into an external groove on a 3/16-inch shaft, holding bearings, collars, or other components in axial position. Applications requiring ISO 13485:2015 compliance will find this ring meets that standard, making it appropriate for certain regulated assembly environments as well.

Key Features

• Fits 3/16-inch (0.1875-inch) shaft diameter with a 0.1750-inch groove diameter
• Beryllium copper construction per ASTM B197 and UNC C17200 for strength and conductivity
• Zinc finish provides corrosion resistance on the ring surface
• Ring thickness of 0.015 inches with a tight tolerance of plus or minus 0.001 inches
• Hardness rated at 84-86 HRC for reliable retention under load
• Meets ISO 13485:2015 standard for regulated assembly applications

Compatibility

Designed as an OEM-style external retaining ring for 3/16-inch shaft diameters with a groove diameter of 0.1750 inches and a groove width of 0.018 inches. Verify groove dimensions against shaft specifications before installation.

Installation Notes

External retaining rings of this size are installed and removed using snap-ring pliers sized for external rings. Power down or de-energize any equipment before servicing shaft assemblies. Confirm the shaft groove dimensions match the ring specifications precisely, as mismatched tolerances can result in ring ejection under load. Follow applicable ANSI and equipment manufacturer guidelines for shaft retention hardware.
