Miniature flange ball bearings usually refer to small bearings with an inner diameter of 1-9mm, which belong to miniature deep groove ball bearings. Flanged miniature bearings have a solid steel flange on the outer ring. This allows for easier positioning of the bearing in the housing. The flange also helps prevent axial movement of the bearing when thrust loads are applied to the bearing. It is easier to maintain the flange bearing position in applications where there is a lot of vibration. Flanged bearings are sometimes used where the housing is made of a different material and may expand more than the bearing outer ring at higher temperatures. The resulting loose fit may allow non-flange bearings to move within the housing.
According to the size and structure of miniature flanged ball bearings, the models of major bearing companies in the world are slightly different. The Japanese NMB bearing model is marked with letters + outer diameter size + inner diameter size, so that users can intuitively understand the product size. Other bearing brands such as NSK bearings, model numbers Marked as MR bearings, this method adopts international standards and is relatively common in the industry. Miniature flanged ball bearings, compact structure, small installation space, small starting torque, often used in high-speed, low-noise products.
Many very small flanged bearings are made from stainless steel as they are not used in high load applications and since the small amount of steel used the cost difference is negligible. Flanged chrome steel bearings with steel cages and suitable lubricants can be used at a constant temperature of 120°C or at intermittent temperatures up to 150°C. Above these temperatures, the load carrying capacity of chrome steels decreases and the steel undergoes greater dimensional changes than stainless steels.
Chrome steel flanged bearings are not resistant to corrosion and are coated with a layer of anti-corrosion oil to prevent moisture. We do not recommend using these bearings without any lubricant (dry) as they are prone to corrosion. This can even occur during storage or transport due to condensation forming inside the protective packaging.
The standard cage or retainer for chrome steel flanged miniature bearings is made of SPCC steel strip. Due to space constraints, one-piece crown cages are more suitable for the smallest and thinnest bearings.

AUB chrome steel flanged miniature bearings are available as open or with metal shrouds. Larger sizes may have rubber or PTFE contacting seals or low friction non-contacting rubber seals. Open flange bearings are lubricated with light oil. Bearings with shielded or sealed flanges are usually grease lubricated, but shielded bearings are available with instrument oil for low speed, low friction applications. Thanks to our in-house relubrication facility, these bearings can be supplied with customer specified oil, grease or dry lubricant.
