Value Collection 30906 Set Screw Shaft Collar 1-3/4 in Od

Product Description

The VALUE COLLECTION 30906 is a set screw style shaft collar designed to locate, space, and secure rotating or stationary components on a shaft. Machined from steel, it features a 1-3/4 inch outside diameter, a 1.125 inch bore diameter, and a 5/8 inch width. The set screw locking mechanism bites directly into the shaft to resist axial movement without requiring keyways or grooves. This collar is a standard component in mechanical assemblies and is typically installed by millwrights, maintenance technicians, and mechanical contractors working on conveyor systems, motors, gearboxes, and industrial drive trains. Each package contains two collars.

Set screw shaft collars in this bore and OD range are widely used in light to medium-duty mechanical applications including pump assemblies, fan shafts, roller conveyor systems, and motor-driven equipment. The 1.125 inch bore accommodates standard shaft stock. The steel construction handles the clamping forces generated by the set screw and provides adequate strength for most general industrial and commercial mechanical service environments. This collar suits both new assembly and field replacement scenarios where precise shaft component positioning is required.

Key Features

• Set screw locking style — no keyway or groove required on the shaft
• 1-3/4 inch outside diameter and 1.125 inch bore for standard shaft sizing
• 5/8 inch width provides a stable, low-profile bearing surface
• Steel construction for durability under clamping load and mechanical stress
• Sold as a 2-piece package — useful for paired collar configurations

Compatibility

Designed as a general-purpose OEM-style replacement or new-assembly shaft collar for mechanical equipment using 1.125 inch diameter shaft stock.

Installation Notes

Shaft collars of this type are installed by millwrights and mechanical technicians using standard hex keys to tighten the set screw against the shaft. Ensure the shaft and bore surfaces are clean and free of burrs before positioning the collar. De-energize and lock out all rotating equipment per OSHA lockout/tagout procedures before installing or repositioning any shaft hardware. Do not over-torque the set screw, as this can damage the shaft surface or strip the screw threads.
