An open bearing spins with less drag than a shielded one because there is no seal rubbing, and it can be flushed and re-oiled easily. That makes it the right choice for sealed positions inside a gearbox or differential, where the housing already keeps dirt out and what you want is minimum friction.\u003c\/p\u003e\u003cp\u003eWhat it is not right for is any position exposed to dirt. Without a shield, off-road grit reaches the races within a run or two, and once inside it grinds them, drags on whatever the bearing supports, and eventually seizes. If you are replacing a bearing in an exposed hub position, you want the shielded equivalent instead.\u003c\/p\u003e\u003cp\u003eNote that Kyosho makes a similar 8 x 16mm bearing in a 5mm width, so check the width as well as the bore before ordering. Two are supplied. Bearings are consumables: if one feels rough spun between your fingers, replace it rather than cleaning it.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532858126424,"sku":"KYOBRG012O","price":7.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/kyobrg0120_178328bb-0595-4b37-b441-1f6cd82d7590.jpg?v=1786242894","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-brg012o-8x16x4mm-open-bearing-2pcs","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
