Miniature Flanged Ball Bearings With Extended Inner Ring

Miniature Flanged Bearings with Extended Inner Ring have an inner ring that is wider than the outer ring. The wide inner ring eliminates the need for spacers or washers.

Double Benefits: Flange and Extended Inner Ring

This bearing features a distinctive composite design, with an outer ring flange for axial positioning and an extended inner ring.

The flange allows direct axial fixation during installation into the housing hole, eliminating complex shoulder machining or additional cover plates, thus simplifying housing design and processing.

The extended inner ring offers improved positioning for mating parts (like gears and pulleys), allowing them to directly contact the inner ring end face without needing extra spacers or sleeves.

This dual-simplified installation of both rings significantly enhances assembly efficiency while reducing component count. It also minimises cumulative errors from multi-part coordination, ensuring precision in the installation process.

Stable Support in Compact Design

Although this product is a compact miniature bearing, its design with a combined flange and extended inner ring provides strong support capacity in a small volume.

The outer ring flange ensures reliable axial fixation, effectively limiting axial movement within the housing. It maintains stability even under impact loads or high vibration conditions.

The extended inner ring increases contact length with the shaft, enhancing support span and fit stability. This helps distribute load, reduce shaft deflection, and improve the overall rigidity of the rotating system.

This composite design allows the bearing to withstand radial and moderate axial loads in confined spaces while ensuring good operational stability.

Highly Integrated Solution

This bearing integrates the functions of axial positioning and fixation on the shaft into one. This means that in the design, multiple peripheral parts such as retaining rings, spacers, shaft shoulders, and shaft sleeves used for axial positioning in traditional schemes can be omitted.

This highly integrated feature not only directly reduces the number of parts on the bill of materials (BOM), simplifies procurement and inventory management, but more importantly, it streamlines the overall structure of the product, making the final equipment more compact and lightweight.

If you’ve been concerned about the complexity involved in purchasing and installing bearings, rest assured—this type of bearing from TFL Bearing is designed to be a perfect solution for you.

FREQUENTLY ASKED QUESTIONS

How do the flange and extended inner ring work together?

There is no standard answer for the lubrication cycle of bearings. It needs to be adjusted according to your current situation.

Generally, there are several influencing factors:

Load: Under high load, the aging speed of the lubricant is faster, and more frequent lubrication is required.
Speed: The higher the speed, the higher the demand for lubricant.
Temperature: High temperature can easily cause the lubricant to oxidise, while low temperature can make the lubricant thicker.
Type of lubricant: Different lubricants have different performance and lifespan, and it is necessary to carefully read the relevant information of the lubricant.
Type of seal: The better the sealing performance, the better the protection of the lubricant, and the longer the lubrication cycle.
