- Thrust bearings, on the other hand, are designed to support axial loads within the engine or machinery. In an engine, thrust bearings are typically located at the end of the crankshaft to counteract the axial forces generated by the engine's operation. They are responsible for maintaining the axial position of the crankshaft and preventing it from moving forward or backward.

   - Cylindrical Roller Bearings: Cylindrical roller bearings are not designed to accommodate misalignment to the same extent as spherical roller bearings. They are primarily intended for applications where precise shaft positioning and minimal deflection are critical.

In summary, the key differences between needle roller bearings and cylindrical roller bearings lie in their design, load-carrying capacity, and application suitability. Each type of bearing is tailored to meet specific operational requirements and environmental conditions in diverse industrial applications.
