Friction remains low, reducing operating temperature and energy consumption. The precise guidance of the rollers ensures smooth running and reproducible results.\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\u003eIn operation, this results in high load-bearing capacity with a compact design and consistent vibration and temperature levels. Easy-to-assemble designs and suitable lubrication concepts help reduce downtime. Precise fits and carefully machined seating surfaces are essential for consistently stable performance.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eSummary\u003c\/strong\u003e\u003cbr\u003e Slim, load-bearing and low-friction – for stable processes under radially dominant loads.","brand":"FAG","offers":[{"title":"Default Title","offer_id":53637901582676,"sku":"RNA4900-RSR-XL","price":0.0,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/metabearings-shop.com\/en\/products\/rna4900-rsr-xl","provider":"Meta Bearings","version":"1.0","type":"link"}
