The hidden side of needle roller bearings.
There are many types of bearings, the most common are ball bearings, or tapered roller bearings, cylindrical or spherical roller bearings. Their design meets certain technical requirements to adapt to the specific application. Less known is the needle roller bearing , but it is indispensable in certain applications where high demands are made on reliability and durability. Discover the hidden side of needle bearings that fit into many mechanisms. What is so special about them? The rolling elements used are shaped like needles, hence the name. These steel needles with a round or flat tip have a diameter of no more than 5 mm, and their length must be at least 3 times greater than their diameter. The bearing supports very high loads thanks to the contact the area developed by the needles, which are mounted in a cage made of steel or molded polyamide. It allows for extremely compact assemblies and is the bearing of choice when looking for a good compromise between performance...
