Rolamentos em miniatura

Overview
Miniature bearings are precision components characterized by their small size, typically with an outer diameter of less than 30mm. Despite their compact dimensions, they are engineered to provide reliable rotational motion, high accuracy, and low noise. These bearings are essential in applications where space is severely limited, and precise motion control is critical, such as in medical devices, robotics, precision instruments, and small motors.

Features of Miniature Bearings

Defined by their small size and compact structure, with outer diameters often under 30mm.

Manufactured to high-precision grades to ensure smooth and accurate operation.

Available in various configurations, including open, shielded, or sealed types for different environmental needs.

Can be supplied with different clearance levels to suit specific operational requirements (e.g., high speed or low noise).

Constructed from high-carbon chromium bearing steel (e.g., SUJ2), stainless steel (e.g., AISI 440C), or ceramic materials for corrosion resistance and durability.

Designed for high rotational speeds and low starting torque.

Capable of supporting combined radial and light axial loads.

Benefits of Miniature Bearings

Space-Saving Design: Their miniature size enables integration into compact and complex mechanisms where standard bearings cannot fit.

High Precision and Smooth Operation: Precision manufacturing ensures minimal runout and vibration, which is crucial for the accuracy of sensitive equipment.

Low Noise and Vibration: High-quality manufacturing and materials contribute to quiet and smooth running, essential for consumer electronics and medical devices.

Reliable Performance in Demanding Conditions: Options like stainless steel and ceramic materials offer excellent resistance to corrosion, heat, and degradation.

Versatility and Wide Applicability: Their small size and reliable performance make them indispensable across diverse sectors, from aerospace and defense to office automation.

Long Service Life: Precision engineering and high-quality materials ensure extended durability and reduced failure rates, even in continuous operation.
