Are You Familiar With Insert Bearings?

Insert bearings are simply standard radial bearings that have been adapted to fit into a housing, which is why they are often referred to as adapted radial bearings. While they are commonly sold with a housing, they can also be purchased without one. Along with wide inner ring bearings, insert bearings are used in many different industries, from agriculture and food processing, to printing.

Both types of insert bearings are used for mounting on shafts. Standard bearings require specific installation tools to be pressed into a shaft, while insert bearings can be slip-fit directly onto the shaft and locked into place using setscrews or a locking device. To accommodate the locking collar and provide extra shaft support, the inner ring of the bearing extends to one or both sides.

Wide inner ring bearings, which are inserts used for heavier-duty applications, feature a wider inner ring that extends past the width of the outer ring on both sides. The extension on one side accommodates a heavy-duty seal while the other extended side holds another seal and the locking device. These inserts have become increasingly popular as an affordable bearing option that can fit most applications.

It’s important to note that not all applications will be able to accommodate a one-size-fits-all insert bearing. Make sure you understand the specifications of your particular application before making your purchase. If you need further assistance, be sure to speak to your quality bearing supplier about what options would suit your application the best. We are always here to help!
