3*7*3 High-Precision SMD Power Inductor, RF/Telecom, Automotive Grade

3x7x3 precision bearings
3x7x3 micro bearings
3x7x3 ball bearings
3*7*3 (precision level)
Compact 3x7x3 precision bearings for high-accuracy micro applications. These 3x7x3 micro bearings feature miniature sizing (3x7x3mm) with smooth-rolling ball bearings design. Optimized for low friction and high-speed performance in robotics, electronics, and precision instruments. Durable 3x7x3 ball bearings ensure reliable operation in confined spaces.

Product Description

The 3x7x3 precision bearings are high-performance micro bearings designed for applications requiring exceptional accuracy and minimal friction. With dimensions of 3mm inner diameter, 7mm outer diameter, and 3mm thickness, these ball bearings feature stainless steel construction and sealed lubrication for durability in harsh environments. They operate seamlessly within a temperature range of -30°C to +120°C and support radial loads up to 150N, making them ideal for robotics, medical devices, and optical instruments. These 3x7x3 micro bearings enable direct integration with compact servo motors, rotary encoders, and miniature gear systems. While offering low-noise operation and extended service life, their small size limits axial load capacity. The 3x7x3 ball bearings are widely adopted in precision industries due to their repeatability under 0.001mm and RPM tolerance exceeding 25,000, though regular maintenance is required for optimal performance.
