Their low-friction geometry promotes consistent temperatures and low power losses. The defined guidance of the needle rollers ensures smooth running and reproducible processes.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eDesign and manufacturing quality\u003c\/strong\u003e \u003cbr\u003eThe design relies on the linear contact of slim rollers, optimized profiling for edge relief, and precise cage guidance. Versions in the NK\/RNA series utilize the hardened and precision-machined shaft as the inner raceway, eliminating the need for an inner ring and further reducing the overall height. Alternatively, versions with an inner ring are available for applications requiring specific fit ratios. Depending on the model, sealed variants are available to retain lubricant within the bearing and reduce particle ingress. The cage is constructed of sheet steel, which stabilizes the roller guidance and minimizes friction peaks.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eConvincing in everyday life\u003c\/strong\u003e \u003cbr\u003eThe result is high radial load ratings in confined spaces, as well as stable temperatures and low vibrations. Assembly-oriented designs and a suitable lubrication regime support short downtimes. Prerequisites for consistently stable performance are precise fits and carefully machined seating surfaces.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eSummary\u003c\/strong\u003e\u003cbr\u003e Compact, durable and efficient – ​​ideal when radial forces dominate and installation space is limited.","brand":"FAG","offers":[{"title":"Default Title","offer_id":53637921538388,"sku":"RNA4908-2RSR-XL","price":0.0,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/metabearings-shop.com\/en\/products\/rna4908-2rsr-xl","provider":"Meta Bearings","version":"1.0","type":"link"}
