This bearing features an \u003cstrong\u003eOuter Diameter\u003c\/strong\u003e of \u003cstrong\u003e56 mm\u003c\/strong\u003e, an \u003cstrong\u003eInner Diameter\u003c\/strong\u003e of \u003cstrong\u003e30 mm\u003c\/strong\u003e, and a \u003cstrong\u003eWidth\u003c\/strong\u003e of \u003cstrong\u003e13 mm\u003c\/strong\u003e, providing a compact footprint for tight assembly spaces. Manufactured from high-grade \u003cstrong\u003eChrome Steel\u003c\/strong\u003e, the component delivers a \u003cstrong\u003eLoad Rating (dynamic)\u003c\/strong\u003e of \u003cstrong\u003e15.4 kN\u003c\/strong\u003e and a \u003cstrong\u003eLoad Rating (static)\u003c\/strong\u003e limit of \u003cstrong\u003e8.6 kN\u003c\/strong\u003e, ensuring robust load support under both rotating and stationary conditions. Its \u003cstrong\u003eDouble Shielded (ZZ)\u003c\/strong\u003e sealing type offers enhanced protection against dust and moisture ingress, while maintaining consistent lubrication retention. Weighing just \u003cstrong\u003e0.23 kg\u003c\/strong\u003e, this bearing contributes minimal mass to the overall system without compromising durability or structural integrity.\u003c\/p\u003e\n\n\u003cp\u003eThe PMM-BA-5603-8 bearing achieves high-speed performance up to a \u003cstrong\u003eMaximum Speed (grease)\u003c\/strong\u003e of \u003cstrong\u003e9,000 rpm\u003c\/strong\u003e under standard grease lubrication, leveraging its optimized internal geometry and material composition. The inclusion of \u003cstrong\u003eRadial Clearance\u003c\/strong\u003e rated \u003cstrong\u003eC3\u003c\/strong\u003e accommodates thermal expansion and high rotational velocities, reducing the risk of seizure or excessive friction at elevated temperatures. Precision manufacturing to \u003cstrong\u003eTolerance\u003c\/strong\u003e standards of \u003cstrong\u003eABEC-3\u003c\/strong\u003e delivers low vibration and noise levels, supporting smooth, repeatable motion. An \u003cstrong\u003eInput Resistance\u003c\/strong\u003e of \u003cstrong\u003e330 Ω\u003c\/strong\u003e and a \u003cstrong\u003eMaximum Input Frequency\u003c\/strong\u003e of \u003cstrong\u003e100 kpps\u003c\/strong\u003e ensure compatibility with modern motion control drives, enabling responsive feedback loops and fine position adjustments. These combined technical features yield a stable operational profile across the specified \u003cstrong\u003eTemperature Range\u003c\/strong\u003e of \u003cstrong\u003e-30°C to 120°C\u003c\/strong\u003e, making the bearing well-suited for thermal cycling environments.\u003c\/p\u003e\n\n\u003cp\u003eReliability is further enhanced by the robust chrome steel construction and dual shielding, which minimize wear and corrosion over the component’s service life. Integration into servo drive systems is simplified by its standard dimensions (56 x 30 x 13 mm) and established sealing configuration, allowing seamless replacement or upgrade of existing ball bearing modules. The lightweight design at \u003cstrong\u003e0.23 kg\u003c\/strong\u003e ensures minimal impact on inertia calculations, promoting agile response in dynamic motion applications. Commonly deployed in industrial automation, robotics, and precision servo assemblies, the PMM-BA-5603-8 bearing supports high-speed spindles, rotary encoders, and other critical rotating elements that demand both accuracy and longevity.\u003c\/p\u003e","brand":"Sanyo Denki","offers":[{"title":"Refurbished","offer_id":52057325863213,"sku":null,"price":1246.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PMM_PentaSYN_Servo_Drives__fc50d450-e699-4b3f-8249-bf355bab7bf5.webp?v=1760382727","url":"https:\/\/servosupplier.com\/products\/pmm-ba-5603-8","provider":"Servo Supplier","version":"1.0","type":"link"}
