This \u003cstrong\u003eType: Retaining Ring\u003c\/strong\u003e features an \u003cstrong\u003eStyle: External\u003c\/strong\u003e design, optimized for installation into grooves on shafts or cylindrical members. Constructed from premium \u003cstrong\u003eMaterial: Steel\u003c\/strong\u003e, the ring exhibits a precise \u003cstrong\u003eOuter Diameter: 4.750 in\u003c\/strong\u003e and an \u003cstrong\u003eInner Diameter: 3.760 in\u003c\/strong\u003e for accurate seating. With a \u003cstrong\u003eThickness: 0.062 in\u003c\/strong\u003e and a \u003cstrong\u003eWidth: 0.437 in\u003c\/strong\u003e, it delivers a low-profile solution that maintains consistent axial retention without threaded fasteners. The ring’s \u003cstrong\u003eGroove Diameter: 4.625 in\u003c\/strong\u003e and \u003cstrong\u003eGroove Width: 0.078 in\u003c\/strong\u003e ensure a secure fit within standard channel specifications.\u003c\/p\u003e\n\n\u003cp\u003eThe performance characteristics of the E4809-045-076-C are underpinned by its durable \u003cstrong\u003eCoating\/finish: Phosphate\u003c\/strong\u003e, which enhances corrosion resistance and provides a matte exterior suitable for harsh environments. Rated for a \u003cstrong\u003eMin Operating Temperature: -40°F (-40°C)\u003c\/strong\u003e up to a \u003cstrong\u003eMax Operating Temperature: 250°F (120°C)\u003c\/strong\u003e, the ring maintains mechanical integrity across wide thermal ranges. Its steel composition offers superior abrasion resistance and repeated mechanical loading durability, ensuring reliable axial load retention in demanding applications. The external retaining style simplifies assembly and disassembly processes, reducing downtime during maintenance cycles. Precision manufacturing yields consistent dimensional tolerances, resulting in uniform retention force and minimized vibration in high-speed or high-vibration environments. The robust design supports integration with motor housings, gear packages, and bearing arrangements without compromising performance.\u003c\/p\u003e\n\n\u003cp\u003eOkuma’s E4809-045-076-C excels in reliability and ease of integration within industrial automation systems. Its standardized dimensions and proven steel construction facilitate straightforward retrofitting into existing CNC control board setups and mechanical assemblies. The phosphate finish contributes to long-term oxidation resistance, further extending service life in moisture-prone or corrosive settings. Engineers benefit from the component’s fatigue resistance and stable retention characteristics, enabling consistent operation under cyclic loading. Ideal for applications ranging from machine tool spindles to precision gearboxes, this retaining ring ensures dependable axial retention where uniform force distribution and component security are critical.\u003c\/p\u003e","brand":"Okuma","offers":[{"title":"Refurbished","offer_id":51844342939949,"sku":null,"price":380.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/E4809_Board_Series__01HRANC81A9SM4EBQ9SFQFQN8M_eb4f8b92-aa66-4485-9813-23880fb2e733.webp?v=1757360339","url":"https:\/\/servosupplier.com\/products\/e4809-045-076-c","provider":"Servo Supplier","version":"1.0","type":"link"}
