Miniature bearings play a crucial role in today’s advanced engineering, where space is minimized but precision cannot be compromised. From medical equipment to robotics and aerospace, these compact components deliver reliable performance under demanding conditions. At KINEX BEARINGS, we design miniature bearings that combine high accuracy with durability for specialized applications.
What Are Miniature Bearings?
Miniature bearings are rolling elements with bore sizes typically below 10 mm. Despite their small size, they are engineered to handle high rotational speeds and required load capacity. Materials may include special requirements for stainless steel, hybrid ceramics, advanced lubricants, and extended service life for specific applications.
Key Characteristics of Miniature Bearings
- Ultra-compact design for restricted spaces
- High precision for critical applications
- Low acoustic noise and vibrations
- Available in stainless steel and ceramic variants
