This is a bearing with an internally threaded hole.
There are various methods to mount bearings, including attaching flanges, fixing with collars at both ends, using retaining rings, pressing into the shaft or housing, etc. For our main products, plastic bearings, the common method is to press fit the outer diameter to secure the bearing. Among these different mounting methods, as shown in the photo, it is also possible to equip the bearing with an internal threaded hole and fix it with a screw.
Depending on the bearing size, it is possible to manufacture thread sizes and pitches in the dimensions you specify. If you have any issues with mounting plastic bearings, please do not hesitate to contact us.
