{"product_id":"3309-atn9","title":"3309 ATN9","description":"3309 ATN9 – Angular contact ball bearing (double row) for space-saving double bearing function.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eQuality that safeguards processes\u003c\/strong\u003e\u003cbr\u003e This bearing design is intended for combined loads. Double-row versions carry axial loads in both directions and simultaneously absorb radial forces. They compactly replace a bearing pair and save installation space. The focus is on smooth running, high speed capability, reproducible results, and defined axial guidance.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eDesign and manufacturing quality\u003c\/strong\u003e \u003cbr\u003eStaggered raceways with a defined contact angle in each row ensure axial stiffness. Finely machined raceways reduce friction and promote smooth running. The cage is made of fiber-reinforced polyamide. Double-row designs combine the function of a bearing pair in a compact form. In this design, the open construction remains low-friction and simplifies lubrication. The outer ring features a groove with a snap ring (NR) for positioning. Tolerances are within tolerance class Normal (P0). Angular adjustability is limited; precise alignment is recommended.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eConvincing in everyday life\u003c\/strong\u003e\u003cbr\u003e In practice, consistent stiffness, uniform temperature and vibration levels, and predictable quality are observed even with frequent start\/stop cycles and high cutting data. Other bearing designs are better suited for purely radial heavy loads.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eSummary\u003c\/strong\u003e \u003cbr\u003eIn summary: speed-resistant, axially guiding and dimensionally stable – for stable processes and reliable results.","brand":"SKF","offers":[{"title":"Default Title","offer_id":53540386144596,"sku":"3309ATN9","price":0.0,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/metabearings-shop.com\/en\/products\/3309-atn9","provider":"Meta Bearings","version":"1.0","type":"link"}
