E4809-045-076-C

The Okuma E4809-045-076-C retaining ring is part of the robust E4809 CNC Boards series by Okuma, engineered for seamless integration into high-performance industrial assemblies. This Type: Retaining Ring features an Style: External design, optimized for installation into grooves on shafts or cylindrical members. Constructed from premium Material: Steel, the ring exhibits a precise Outer Diameter: 4.750 in and an Inner Diameter: 3.760 in for accurate seating. With a Thickness: 0.062 in and a Width: 0.437 in, it delivers a low-profile solution that maintains consistent axial retention without threaded fasteners. The ring’s Groove Diameter: 4.625 in and Groove Width: 0.078 in ensure a secure fit within standard channel specifications.

The performance characteristics of the E4809-045-076-C are underpinned by its durable Coating/finish: Phosphate, which enhances corrosion resistance and provides a matte exterior suitable for harsh environments. Rated for a Min Operating Temperature: -40°F (-40°C) up to a Max Operating Temperature: 250°F (120°C), 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.

Okuma’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.
