Needle roller bearings are bearings with cylindrical rollers whose diameter is smaller than their length. Compared to other roller bearings they are smaller and considerably lighter, yet can withstand heavy loads. This means machines can be made more compact and lightweight, thus saving costs. They are widely used for their high reliability in the automotive and engineering industries.
The modified rollers and raceway profile prevents stress peaks and extends the bearing operating life.
Needle roller bearings are produced in many different designs, series and in a wide range of sizes, which make them suitable for a wide variety of operating conditions and applications.
Needle roller bearings are especially useful for very compact solutions with a limited installation space in the radial direction and where a high load bearing capacity is required. Needle bearings, except for thrust and combined needle bearings, cannot sustain axial loads.
