They save radial space while supporting heavy loads with low rotational friction.\nHere’s the short setup rundown:\n- High radial load per diameter, ideal for tight spaces and slim housings\n- Common choice for linear slide unit and cam follower applications requiring low profile bearings\n- Works well as an alternative to sealed ball bearing when axial load is minimal and lubrication access is available\n- Look for oil-hole designs and high carbon steel options for easy lubrication and durability\u003c\/p\u003e","brand":"Bearings Canada","offers":[{"title":"Default Title","offer_id":52511454331199,"sku":"861977","price":91.88,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/4750\/8031\/files\/caged-needle-roller-bearing-rna4905.jpg?v=1776636482","url":"https:\/\/bearingscanada.com\/products\/single-caged-needle-roller-bearing-rna4905-machine","provider":"Bearings Canada","version":"1.0","type":"link"}
