Midwest Fasteners External E-Ring Carbon Steel Shaft Retaining Ring

Midwest Fasteners External E-Ring Carbon Steel Shaft Retaining Ring

Midwest Fasteners offers this external E-ring retaining ring in carbon steel, engineered to snap into a machined groove on a shaft and hold bearings, pulleys, gears and bushings securely in place against axial movement. This family spans sizes from 3/16" up to 5/8" — including 7/32", 1/4" x 1/4", 5/16", 3/8", 7/16" and 1/2" — so you can match the ring directly to the shaft groove diameter you are servicing. Every size in this line shares the same carbon steel construction, giving each ring the spring tension needed to seat firmly in the groove and resist working loose under vibration, making it a dependable choice for equipment assembly, repair and maintenance work wherever a shaft-mounted E-ring is called for. Because each size is sized to a specific shaft groove dimension, confirm your groove diameter before ordering to ensure proper fit and holding power.

Key Features

• Size Range: Available from 3/16" through 5/8" (3/16", 7/32", 1/4" x 1/4", 5/16", 3/8", 7/16", 1/2", 5/8"), each sized to a matching shaft groove diameter.
• Material & Finish: Carbon steel construction provides the spring tension needed for a secure, self-retaining grip on the shaft.
• Type: External E-ring style retaining ring, designed to snap onto the outside of a shaft rather than inside a bore.
• Function: Holds bearings, pulleys, gears, bushings and other rotating or sliding components in a fixed axial position.
• Installation: Installs quickly with standard retaining ring pliers onto a pre-machined shaft groove, with no tools beyond common pliers required.
• Consistency: A uniform carbon steel spec across the entire size range simplifies stocking for shops servicing multiple shaft diameters.
