They are tailored specifically for the demands of cycling. \u003c\/span\u003e\u003cspan\u003eEvery aspect of an Enduro bearing is considered and spec’d to provide superior performance and value for each application. From the material of the races and the ball bearings, the types of seal and even the grease. Each of these has a profound effect of the performance and longevity of a bearing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eWhat is ABEC?\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe ABEC grade of bearings is a set of standards for the manufacturing tolerances of bearings. There are five classes from largest to smallest tolerances: 1, 3, 5, 7, and 9. The higher ABEC classes provide better precision, efficiency and greater speed capabilities, but do not necessarily make the components spin faster. All quality manufacturers around the world manufacture to at least ABEC 1 standard. Enduro’s Minimum Standard is ABEC 3.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eWhat is the meaning of Ball Grade?\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBearing balls are manufactured to a specific grade, which defines its geometric tolerances (or roundness). The smaller the number the higher the precision. A grade 20 ball for instance is 20\/1,000,000\" out of round.

They also fill both sides of the bearing for maximum lubrication, unlike industrial bearings which are only single filled. Wheel bearings (usually 2RS or LLB suffix) contain a low friction, temperature stable grease, whereas a Frame Pivot Bearings (MAX type) will contain a thicker waterproof marine type grease.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eSeals\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e2RS: Literally means the bearing has Two Rubber Seals. There are many types of seals. On most other bearings 2RS means that the seal is made from rubber and has one sealing lip rubbing on any flat part of the inner race. Enduro’s seals are usually either LLU (usually the MAX type bearings) or LLB (better for hubs).\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eLLU Seals: Two NBR 70 rubber seals with medium\/high contact seal, which rides in a matching groove machined into the bearing to make a labyrinth type seal.

Always press on the outer race with a pilot bushing or similar tool, which will only make contact with the metal side of the outer race. A bearing press or similar should be used to exert the force needed to press the bearing into the housing. Ensure that the seating surface is clean and free from rough edges so that they fit true and square. Quite often bearings can feel fine before fitting, but then feel \"notchy\" or \"rough\" after fitting. This is almost always due to the bearings not sitting square and true. Care needs to be taken that the bearing is started straight and not at an angle to the housing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eBearing Care\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTo prolong the life of your bearings, do not direct a high jet of water near areas of your bike where there bearings are located - an ingress of water can lead to premature bearing failure.\u003c\/span\u003e\u003c\/p\u003e","brand":"Enduro","offers":[{"title":"Default Title","offer_id":52106745610522,"sku":"BEEN2072","price":20.9,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0591\/3441\/0950\/files\/15307_llu-llb_1.jpg?v=1776733185","url":"https:\/\/rider18.co.nz\/products\/enduro-mr15307-llu-llb-abec-5-bearing","provider":"Rider 18","version":"1.0","type":"link"}
