This 55 mm bore, 120 mm outside diameter duplex pair provides 29 mm per bearing width (58 mm total), a 15° contact angle, light preload (DUL), and uses a CR outer land riding cage with an MBR phenolic cage. It delivers ISO P4S precision (ABEC 7\/9 equivalent) with dynamic radial load ratings of 98,700 N per bearing (Ce), 89,800 N ISO dynamic (C1), and a static rating of 58,300 N (C0), plus limiting speeds of 9,300 rpm grease and 15,800 rpm oil. Common applications include CNC machining centers, high-speed milling, grinding machines, jig borers, and precision lathes requiring high rigidity and thermal stability.\u003c\/p\u003e\u003c\/div\u003e","brand":"Timken","offers":[{"title":"New","offer_id":46242680701162,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-008.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/timken-2mm311wicrdul-angular-contact-ball-bearing","provider":"GTG Hardware","version":"1.0","type":"link"}
