It’s a specialized roller that follows cam profiles and guides linear motion with high load capacity.\n- Transfers heavy radial loads in cam mechanisms and linear slide units, often used instead of sealed ball bearing options\n- Common in conveyors, indexing tables, and automation systems where reliable guided travel is needed\n- Full-complement crowned rollers improve contact area and reduce edge stress, helping linear slide units last longer\u003c\/p\u003e","brand":"Bearings Canada","offers":[{"title":"Default Title","offer_id":52511404327231,"sku":"862704","price":203.11,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/4750\/8031\/files\/7e36e39f3a87e45af5a23542557ce754.png?v=1776637782","url":"https:\/\/bearingscanada.com\/products\/roller-follower-bearing-nart20vr-metric-cam-style","provider":"Bearings Canada","version":"1.0","type":"link"}
