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 chrome steel, they deliver exceptional hardness and superior load-bearing capacity for 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 a shielded design, they effectively retain lubrication and protect internal components against contamination and debris ingress, 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 chrome steel balls, they exhibit exceptional hardness and outstanding rolling contact fatigue resistance, ensuring smooth and reliable operation under high-speed, heavy-load environments such as food processing, medical devices, and laboratory instrumentation.

Why choose chrome steel for the ring material?

Chrome steel is the preferred choice for bearing ring material in applications where maximum hardness and superior load-bearing performance are the primary requirements. Its high carbon and chromium content delivers exceptional surface hardness, outstanding rolling contact fatigue resistance, and excellent wear durability, ensuring that the inner and outer rings maintain precise geometry and smooth operation under demanding high-speed and heavy-load conditions. This makes chrome steel rings particularly well-suited for industrial machinery, precision instruments, automotive components, and high-performance equipment where mechanical strength and extended service life are equally important.

Why choose a shielded seal type for your bearing?

For Miniature Flanged Bearings with an Extended Inner Ring, a shielded seal is chosen to maximize high-speed performance and mounting precision. Since the extended inner ring acts as an integrated spacer, metal shields are preferred because they are non-contact, ensuring zero added friction or torque—critical for the delicate, high-RPM motors and instruments where these bearings are used. Additionally, the rigid metal shield is less likely to be damaged or displaced during the assembly of compact mechanical stacks compared to soft rubber seals.

Why choose chrome steel for the ball material?

Choosing Chrome Steel (typically SAE 52100) for the balls in miniature flanged bearings with an extended inner ring is ideal when your priority is maximum load capacity and cost-efficiency. Chrome steel is significantly harder and more durable than stainless steel, allowing it to handle higher radial and axial loads with superior wear resistance and fatigue life. It is the standard choice for high-performance applications in dry, lubricated environments—such as small motors or robotics—where mechanical strength and precision are more critical than corrosion resistance.
