With a 0.25-inch bore diameter and 0.5-inch outside diameter, this compact bearing delivers a dynamic load capacity of 60 pounds. It features a self-aligning design and an engineered-polymer retainer with four ball circuits, making it well suited for motion control assemblies where consistent, low-friction travel is required. Installation is handled by mechanical technicians and machine builders working with linear shafting systems.\u003c\/p\u003e\u003cp\u003eThis bearing is used in light-duty to medium-duty linear motion systems, including automation equipment, instrumentation, and precision positioning assemblies. Its closed bearing style fully encloses the shaft for improved contamination resistance compared to open-style alternatives. The self-alignment feature helps compensate for minor shaft misalignment during assembly, reducing setup time in tight-tolerance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed bearing style for improved shaft enclosure and contamination resistance\u003c\/li\u003e\n\u003cli\u003e60-pound dynamic load capacity suitable for light to medium linear motion loads\u003c\/li\u003e\n\u003cli\u003eSelf-aligning design compensates for minor shaft misalignment\u003c\/li\u003e\n\u003cli\u003eFour ball circuits for balanced load distribution across the bearing length\u003c\/li\u003e\n\u003cli\u003eEngineered-polymer retainer for lightweight construction\u003c\/li\u003e\n\u003cli\u003e0.735-inch overall length in a compact 0.75-inch nominal size envelope\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit linear bearing for 0.25-inch diameter linear shafting in closed-bore linear motion assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical technicians familiar with linear motion systems. Before servicing or replacing linear bearings, ensure all machine power and pneumatic sources are fully de-energized and locked out. Press or slide the bearing into its housing using appropriate tooling  -  do not strike the bearing directly with a hammer, as this can damage the ball circuits or retainer. Verify shaft diameter and surface finish meet the bearing manufacturer's specifications before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Super Ball Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Style\u003c\/strong\u003e: Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 6.35 mm (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 60 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.735 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ball Circuits\u003c\/strong\u003e: 4\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\u003eRetainer Material\u003c\/strong\u003e: Engineered-Polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\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: SUPER4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67910472007986,"sku":"SUPER4","price":70.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ee1f2794383789b813e218140ca8e7a_5f8079a5-296f-499f-a719-32d57cb52f6c.jpg?v=1791198197","url":"https:\/\/voomisupply.com\/products\/thomson-industries-super4-closed-linear-bearing-60-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
