E0241-653-030B by Okuma

The Okuma E0241-653-030B shaft is a precision-engineered component in the E0241 MSM Boards series, designed for high-accuracy industrial automation assemblies. This component features a nominal diameter of 30mm with a diameter tolerance of ±0.02mm, ensuring repeatable fit and alignment in precision mechanical systems. The shaft measures a nominal length of 280mm and weighs approximately 2.5 kg, balancing structural rigidity with manageable mass for dynamic applications. Manufactured from high-strength steel and processed via precision ground finishing, the E0241-653-030B delivers low friction and smooth surface contact for reliable operation. Its induction hardening treatment enhances surface durability, providing wear resistance under cyclic loading and extending component life.

Critical specifications include material: steel, surface finish: precision ground, and heat treatment: induction hardened, ensuring consistent performance. The operating temperature range of –20°C to 120°C covers a broad spectrum of industrial environments, from refrigerated systems to elevated-heat processes. Direct fit mounting type simplifies installation on compatible machinery, while interchangeability must be verified against factory model compatibility lists. Periodic lubrication requirement maintains optimal bearing and support function over long service intervals. Standard industry tolerances on diameter and length guarantee that the shaft integrates without secondary machining, reducing setup time and minimizing thermal or mechanical deformation during operation.

In operation, the shaft’s precision finish minimizes friction and mechanical wear, offering stable rotational dynamics for both cam follower and linear support roles. The induction-hardened surface withstands abrasive contact, preserving dimensional integrity under high-load cycles and supporting applications with frequent start-stop sequences. With a balanced mass of 2.5 kg and consistent geometric form, the shaft absorbs dynamic loading with minimal deflection, ensuring positional accuracy in high-speed systems. The repeatable dimensional characteristics contribute to predictable vibration behavior, reducing resonance risks in multi-axis automatons. Robust performance across the –20°C to 120°C temperature span enables deployment in diverse manufacturing conditions without compromise to mechanical properties.

System integration is streamlined by the shaft’s compatibility with Okuma’s MSM board assemblies, facilitating plug-and-play replacement or upgrade scenarios. The E0241-653-030B excels in applications requiring precision guidance, such as spindle supports in machining centers, linear encoder mounts, or rotary drive couplings. Its straightforward direct-fit design and strict ±0.02mm tolerance reduce commissioning time in automated production lines. This component is ideal for industries including metalworking, packaging machinery, semiconductor handling equipment, and other industrial automation platforms where accuracy, wear resistance, and thermal stability are critical.
