Sealed ball bearing inserts give compact shaft support and keep grease in while keeping dirt out. - Ideal for supporting radial loads in mounted systems like pillow block housings and linear slide units, improving runout control and shaft stability. - Sealed designs and relubrication ports extend service life in dusty or wet industrial environments; choose sealed ball bearing inserts for lower maintenance. - Set-screw locking and wide inner rings help prevent shaft slippage and reduce misalignment in conveyor and general machinery applications. \u003c\/p\u003e","brand":"Bearings Canada","offers":[{"title":"Default Title","offer_id":47739626356954,"sku":"MRO5801","price":484.52,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/2674\/3514\/files\/vxb-bearings-collection_f32c823a-662c-4aea-bf50-6f9781467555.png?v=1775602168","url":"https:\/\/hfbearings.ca\/products\/3-12-in-heavy-duty-wide-inner-ring-set-screw-beari","provider":"H\u0026F Bearings","version":"1.0","type":"link"}
