Engineered for precision and compactness, these miniature flanged ball bearings feature an extended inner ring that provides enhanced shaft support and improved stability under radial loads. The integrated flange ensures secure axial positioning and effortless installation without additional retaining components. Manufactured from premium stainless steel, they deliver outstanding corrosion resistance and consistent low-vibration performance across demanding environments including medical, dental, and laboratory applications.

Precision-crafted for demanding applications where accuracy and reliability are paramount, these miniature flanged ball bearings incorporate an extended inner ring that ensures superior shaft engagement and stable performance under varying radial loads. The flanged outer ring allows for straightforward axial location and tool-free installation, significantly reducing assembly time and complexity. Featuring an open seal design, they allow for direct lubrication access and easy maintenance, making them an ideal choice for controlled environments such as precision instruments, optical equipment, and automated machinery.

Specifically designed for applications that demand both structural integrity and long-term dependability, these miniature flanged ball bearings feature an extended inner ring that delivers enhanced shaft support and consistent stability under radial and axial loading conditions. The integrated flange enables precise axial positioning and seamless installation, minimizing assembly complexity across a wide range of mechanical configurations. Fitted with stainless steel balls, they exhibit exceptional resistance to corrosion and oxidation, ensuring smooth and reliable operation in moisture-rich, hygienic, or chemically exposed environments such as food processing, medical devices, and laboratory instrumentation.

Why choose stainless steel for the ring material?

Stainless steel is an ideal choice for bearing ring material in applications where corrosion resistance and long-term durability are essential. Its natural ability to resist rust, oxidation, and chemical degradation ensures that the inner and outer rings maintain precise dimensional tolerances and structural integrity even under prolonged exposure to moisture, humidity, or corrosive substances. This makes stainless steel rings particularly well-suited for medical instruments, dental equipment, food processing machinery, and laboratory devices where consistent performance and compliance with strict hygiene requirements are equally important.

Why choose an open seal type for your bearing?

Open-type bearings are ideal for high-speed, high-temperature, or externally lubricated applications, as they allow free lubricant flow, generate less friction heat, and support a wider range of lubricants. They are also cost-effective, easy to re-lubricate, and offer better control over internal clearance. However, they provide no protection against dust, moisture, or contaminants, making them suitable only for clean, controlled environments.

Why choose stainless steel for the ball material?

Choosing stainless steel (typically AISI 440C) for the balls in miniature flanged bearings with an extended inner ring is primarily driven by the need for corrosion resistance and longevity. Because these specialized bearings are often used in medical devices, laboratory instruments, or outdoor electronics, stainless steel prevents rust from moisture or chemicals that would otherwise degrade standard chrome steel. Furthermore, it offers the dimensional stability and hardness required to maintain precise tolerances in high-precision miniature applications, ensuring the bearing remains reliable even in sensitive or mildly corrosive environments.
