They are handy for cutting friction, improving alignment, and extending service life.\nHere’s how they help:\n- Support high radial loads in pulleys, hoists, and conveyor systems and work alongside sealed ball bearing or linear slide unit components.\n- Keep cable and belt tracking steady in sheave assemblies; oil holes allow maintenance and longer service intervals.\n- Offer strong static capacity and impact resistance where ceramic options may not be ideal.\u003c\/p\u003e","brand":"MRO","offers":[{"title":"Default Title","offer_id":47969324269803,"sku":"863776","price":544.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/3268\/0683\/files\/5788b7e76ce1c886dc7f22b413e58924.jpg?v=1773719377","url":"https:\/\/vxb.com\/products\/heavy-duty-roller-bearing-nas5013zznr-for-sheaves","provider":"VXB Bearings","version":"1.0","type":"link"}
