Roller bearings for sheaves carry heavy radial loads and keep pulleys turning smoothly under rope or belt tension.\n- Supports heavy radial loading in hoists, cranes, and conveyor sheaves, often preferred over sealed ball bearing designs for sheer load capacity.\n- Allows relubrication via oil-holed inner rings for extended service life compared with sealed or ceramic options.\n- Not intended for precision linear slide unit motion; ideal for pulley, sheave, and rope-guiding applications.\u003c\/p\u003e","brand":"MRO","offers":[{"title":"Default Title","offer_id":47969323057387,"sku":"863909","price":1167.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/3268\/0683\/files\/873cf179b86a001b7aed25442e2ab61a.jpg?v=1773719471","url":"https:\/\/vxb.com\/products\/nas5019zznr-roller-bearing-for-sheaves-95-mm-id-14","provider":"VXB Bearings","version":"1.0","type":"link"}
