Return to List

Characteristics and advantages

Needle roller bearings are bearings with cylindrical rollers with a diameter smaller than the length. Improved roller/raceway shape prevents stress peaks and extends the service life of bearings.

Provide needle roller bearings in different designs, series, and sizes to meet various working conditions and applications.
