E4809-045-145-F

Product Description:

The E4809-045-145-F CNC board part by Okuma is built for exact applications where tight tolerances matter. This stainless steel component, part of the E4809 CNC Boards lineup, is shaped with a precise length of 45 mm and offers a reliable tolerance of ±0.02 mm. It’s not something you throw into a machine casually—it’s clearly meant for serious precision.

It operates without hesitation between -40°C and 200°C, giving it the kind of temperature range you’d want in fluctuating industrial spaces. The pressure rating stands firm at 150 bar, so pressure-related failures are not a concern here. You’re also looking at a hardness of 48 HRC, which contributes to long-term wear resistance under mechanical load. Its outer diameter is 14.50 mm and the inner diameter measures 4.50 mm—not oversized, not under. Just enough to fit right where it’s needed.

What helps it stand out further is the passivated finish, which adds a protective edge to the stainless steel body. This isn’t just for show—it helps reduce corrosion risk and keeps the surface integrity intact over time. The unit weighs 0.025 kg, light but solid enough to give the assembly structure. It also meets RoHS compliance standards, making it suitable for facilities that follow strict environmental guidelines. If your CNC setup needs a part that won’t shift, warp, or give in to tough workloads, the E4809-045-145-F holds its shape and stays steady. Whether it’s handling pressure, heat, or tight-fitting tolerances, this component shows up ready. Not every board part is built this way, but this one checks the boxes for both performance and dependability in critical operations.
