Thrust Ball bearing and Needle Bearing

[baris 1]

Hello all friends, 

My questions about the these two types of bearings. I know that what is purpose of usage. But I don't know where can I use them. If someone knows information about that, please inform me. 

Thanks you all.

Ball-thrust bearings are designed to handle almost exclusively thrust loads in low-speed, low-weight applications. An example of its use would be in the bar stools where they are used to support the seat. Whereas, Needle roller bearings are used in designs that have heavy space restrictions.Needle roller bearings use elongated cylindrical rolling elements with small diameters. They are used in applications where radial space is limited. The diameter to length ratio for the needles varies between 1-to-2.5 and 1-to-10. Due to their small size, they cannot be guided accurately and generate high amounts of friction. They are used at low speeds and oscillating motions as a result. Cages may be used to help guide the needles and improve retention.

Thank you so much for your explanatory reply.
