As one of the most professional insert bearings manufacturers and suppliers in China, DAC is featured by high-quality bearings with different specifications and sizes. Insert bearings also belong to pillow block bearings (http://www.dacbearing.com/detailsc/147.html).

Insert bearings, also known as Y-bearings, are commonly used on conveyer and handling systems, machinery made for agriculture, processing and packaging, textile equipment, unique machinery such as car washes, gym equipment and more. 

Generally, insert bearings are standard radial bearings that have been adapted to fit into a housing.  Although they are always sold with the housing, these bearings may also be purchased as stand-alone products to use as replacements. While standard radial ball bearings must be pressed into a machined shaft, using special installation tools, insert bearings can be slip fit directly onto the shaft. However, insert bearings are typically mounted onto shafts that are slightly smaller than the bearing bore diameter. This loose fitting necessitates a locking device to hold the bearing securely in place. The inner ring of the bearing is extended to one side to accommodate the locking device. In addition, the width of the insert bearings inner ring may vary according to the type of the bearing.
