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.\u003c\/p\u003e\n\u003cp\u003eSet 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSet screw locking style — no keyway or groove required on the shaft\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch outside diameter and 1.125 inch bore for standard shaft sizing\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch width provides a stable, low-profile bearing surface\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under clamping load and mechanical stress\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece package — useful for paired collar configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style replacement or new-assembly shaft collar for mechanical equipment using 1.125 inch diameter shaft stock.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShaft 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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Shaft Collar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.75 inches (42 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718247645490,"sku":"30906","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aab7bb94bb18795965c3a76d28bf2850.jpg?v=1788551135","url":"https:\/\/voomisupply.com\/products\/value-collection-30906-set-screw-shaft-collar-1-3-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
