12×26×9mm Bearing

Updated: 2026-08-06

Overview

The bearing with an inner diameter of 12mm, outer diameter of 26mm, and height of 9mm is a compact and precision-engineered component widely used in small mechanical assemblies. Its design ensures smooth rotational movement while minimizing friction, making it ideal for applications where space and efficiency are critical. This type of bearing is commonly manufactured from high-quality materials like chrome steel (GCr15) or stainless steel, offering excellent durability and resistance to wear. Its standardized dimensions make it compatible with a variety of machinery, from small motors to household appliances.

Structure and Working Principle

The bearing consists of an inner ring, outer ring, rolling elements (usually balls or rollers), and a cage to maintain the spacing of the rolling elements. The inner ring fits onto the shaft, while the outer ring is housed in the machine's structure. When the shaft rotates, the rolling elements reduce friction by rolling between the inner and outer rings. This design ensures efficient power transmission and minimizes energy loss. The cage prevents the rolling elements from colliding, ensuring smooth operation even at high speeds.

Key Features

This bearing is known for its high precision, which is critical for applications requiring minimal vibration and noise. Its compact size allows for use in tight spaces without compromising performance. Additionally, the bearing's load-bearing capacity is optimized for small-scale applications, making it suitable for both radial and axial loads. The choice of material (e.g., chrome steel or stainless steel) further enhances its resistance to wear and corrosion, extending its service life.

Application Areas

This bearing is versatile and finds use in various industries. In the automotive sector, it is used in small motors and gearboxes. In household appliances, it ensures the smooth operation of fans, blenders, and other rotating components. Industrial applications include small machinery, conveyor systems, and precision instruments. Its reliability and efficiency make it a preferred choice for manufacturers seeking durable and high-performance components.

Maintenance and Precautions

Proper maintenance is essential to maximize the bearing's lifespan. Regular lubrication with suitable grease reduces friction and prevents premature wear. Contaminants like dust and debris should be kept away, as they can damage the rolling elements. During installation, avoid applying excessive force, which can deform the bearing. Always use appropriate tools and follow manufacturer guidelines. Inspect the bearing periodically for signs of wear or damage, and replace it if necessary to avoid machinery failure.

B2B Procurement Guide

When procuring these bearings in bulk, consider factors like material quality, load capacity, and speed ratings. Verify certifications and test reports to ensure compliance with industry standards. Establish relationships with reputable suppliers to guarantee consistent quality and timely delivery. Compare prices from multiple vendors, but prioritize reliability over cost savings. Custom orders may be available for specific requirements, such as special materials or tolerances.
