AUBEARING Miniature Bearings include metric, inch, standard, flanged, open, sealed, shielded, chrome steel, stainless steel, ceramic, and plastic bearings, as well as a range of miniature thrust ball bearings. These miniature bearings rotate at high speeds with minimal vibration or noise and are widely used in remote-controlled models, gyroscopes, miniature gearboxes, small motors, instruments, dental equipment, vacuum cleaners, skateboards, fishing rod reels, and more. With such a vast range of applications, AUBEARING maintains a stock of nearly 1,000,000+ miniature bearings, covering thousands of different types. As a recognized leader in the manufacture of precision ball bearings and other medium to large bearings, AUBEARING's catalog details all sizes and varieties offered. Metric sizes have an inner diameter as small as 1.0 mm, and inch sizes have an inner diameter as small as 0.04 inches. Here, you can find the ideal miniature bearings in terms of size, weight, and speed to help you make the right choice for your application.
Materials for Miniature Bearings Chrome steel is the most commonly used material for miniature ball bearings due to its high load capacity and good low-noise characteristics. Chrome steel bearings are also more cost-effective. However, many miniature bearings are made from stainless steel because they are not typically used in high-load applications and require only a small amount of steel. The cost difference between stainless steel miniature bearings and chrome steel miniature bearings is negligible. Chrome steel bearings with steel retainers and appropriate lubricants can be used at constant temperatures of up to 120°C or intermittent temperatures of up to 150°C. Beyond these temperatures, the load capacity of chrome steel decreases, and the dimensional changes are greater compared to stainless steel.
Seals and Shields for Miniature Bearings Most chrome steel miniature bearings from AUBEARING are available in open, metal shielded (Z or ZZ), or sealed forms. Bearings with rubber or PTFE contact seals (RS or 2RS) or low-friction non-contact rubber seals (RZ or 2RZ) are suitable for larger sizes of miniature bearings. Open bearings use lightweight oil lubrication. Shielded or sealed bearings typically come with grease lubrication. Shielded miniature bearings are suitable for low-speed, low-friction applications. Thanks to our in-house relubrication facilities, miniature bearings are lubricated with oil, grease, or dry lubricants as specified by you.
