Midwest Fasteners Carbon Steel Shaft-Style External Retaining Rings

Midwest Fasteners Carbon Steel Shaft-Style External Retaining Rings

Midwest Fasteners Carbon Steel Shaft-Style External Retaining Rings are stamped carbon steel rings engineered to seat into a machined groove cut into the outside of a shaft, locking bearings, gears, pulleys, bushings and other rotating or sliding components in a fixed axial position. This family covers shaft diameters from 1/4" through 3/4", including 1/4", 5/16", 3/8", 7/16", 9/16", 5/8", and 3/4", giving maintenance techs, millwrights and fabricators one dependable carbon steel, external-ring product line to standardize on across an entire shaft diameter range instead of sourcing a different brand for every size. Every size in the range shares the same carbon steel construction and low-profile, external shaft-style geometry, so the ring seats flush against the shaft with no added bulk from a shoulder, nut or collar. Confirm your shaft groove diameter before ordering so the ring you select seats fully and securely.

Key Features

• Size Range: Available in shaft diameters from 1/4" up to 3/4", covering 1/4", 5/16", 3/8", 7/16", 9/16", 5/8", and 3/4" shaft applications.
• Material: Solid carbon steel construction provides the strength needed to resist axial loads and stay seated under vibration and repeated cycling.
• Type: External retaining ring, shaft-style, designed to snap into a pre-cut groove on the outside of a shaft rather than inside a bore.
• Function: Holds bearings, gears, pulleys, bushings and other rotating or sliding components in a fixed axial position on the shaft.
• Fit: Each size is matched to its corresponding shaft diameter for a secure, low-profile fit without the extra bulk of a shoulder, nut or collar.
• Sourcing: One consistent carbon steel ring design across the full 1/4" to 3/4" range simplifies stocking and part selection for repeat maintenance work.

Technical Specifications

• Product Material: Carbon Steel
• Type: External Shaft Retaining Ring
• Shaft Size Range: 1/4" - 3/4"

Typical Applications

• Securing bearings and bushings on rotating shafts in motors, gearboxes and pumps.
• Retaining pulleys, sprockets and gears on shafting in conveyor and drive assemblies.
• General machine repair and maintenance where a shaft-mounted component needs a positive axial stop.
• Fabrication and equipment assembly work requiring a reliable, low-profile shaft retainer across multiple shaft sizes.

Why Midwest Fasteners?

Midwest Fasteners supplies carbon steel external shaft retaining rings sized to exact shaft dimensions, from 1/4" through 3/4", so maintenance techs and fabricators can source the correct part across an entire range without guesswork or mixing brands. Consistent sizing and solid carbon steel construction make these rings a dependable choice for keeping rotating and sliding components correctly positioned on the shaft, whether you're servicing a small pump, a gearbox, or a larger conveyor drive assembly. Standardizing on one external retaining ring line across every shaft diameter in the range means fewer part numbers to track and a consistent, repeatable fit every time a ring needs replacing.
