With a 0.75-inch bore diameter and a dynamic load capacity of 1,130 pounds, this bearing handles demanding radial loads in industrial and mechanical applications. The open design accommodates shaft support configurations where a full housing enclosure is not practical. It features a self-aligning style that compensates for minor shaft misalignment, helping extend service life and maintain consistent motion performance. Installation is handled by mechanical technicians and machine builders working on linear actuator assemblies, guide systems, and automation equipment.\u003c\/p\u003e\u003cp\u003eThis bearing is suited for use in both light industrial and heavy-duty linear motion assemblies. The open bearing style allows it to be mounted on supported shaft configurations without requiring full circumferential housing contact. With 10 ball circuits, it provides smooth, distributed load transfer across the shaft. Typical applications include machine tool slides, automation gantries, robotic axis guides, and industrial linear actuator systems where a 0.75-inch shaft diameter is specified. The round bore and self-aligning design make it adaptable to a range of frame and carriage mounting scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpen bearing style allows use in shaft-support configurations without full housing enclosure\u003c\/li\u003e\n\u003cli\u003eSelf-aligning design compensates for minor shaft misalignment\u003c\/li\u003e\n\u003cli\u003e10 ball circuits distribute load evenly for smooth, consistent linear motion\u003c\/li\u003e\n\u003cli\u003e1,130-pound dynamic load capacity suits demanding industrial linear motion applications\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in mechanical and industrial environments\u003c\/li\u003e\n\u003cli\u003eRound bore with 0.75-inch inside diameter fits standard inch-series linear shafting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade bearing for linear motion systems using 0.75-inch diameter round shafting with open-style ball bushing configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical technicians or machine builders. Power down and de-energize all actuators and motion systems before removing or installing linear bearings. Ensure the shaft surface is clean, free of burrs, and within the manufacturer-specified tolerance range before pressing or sliding the bearing into position. Consult applicable machinery safety standards and the equipment OEM documentation for housing fit and retention ring installation requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Style\u003c\/strong\u003e: Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter (mm)\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 1,130 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.605 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Slot Width\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ball Circuits\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Retaining Ring Grooves\u003c\/strong\u003e: 1.285 inches \/ 1.255 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetaining Ring Groove Minimum\u003c\/strong\u003e: 0.055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlignment Style\u003c\/strong\u003e: Self-Aligning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THOMSON INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SSU12OPN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67914344759602,"sku":"SSU12OPN","price":121.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/587331853f46eab7dc87b59c823e66f1_21f1a058-62c0-4808-a2f4-cad799dece68.jpg?v=1791248792","url":"https:\/\/voomisupply.com\/products\/thomson-industries-ssu12opn-open-linear-ball-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
