Different Types of Bearings (PDF & Charts) | Linquip

1/8/2021· Ball bearings are probably the most common type of bearings that utilize balls as the rolling elements. They are characterized by point contact between the balls and the raceways. As a rule, ball bearings rotate very quickly but cannot support substantial loads, so if the bearing is overloaded, the balls can deform or squish, ruining the bearing.

Thrust Ball Bearings

NSK Thrust Ball Bearings are composed of a "washer-like" bearing ring with raceway grooves for the balls and are classified into flat seats or aligning seats - depending on the shape of the outer ring seat. Designed to handle thrust loads while operating at high speeds, these ball bearings are able to sustain axial loads but not radial loads.

Advantages and Disadvantages of Bearings | JVN Bearings FZE - Manufacturer, Supplier & Wholesaler of Bearings

Roller thrust bearings, much like ball thrust bearings, handle thrust loads. The difference, however, lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical gears.
