Nadella bearings are used in many racecar applications because of their small size, low weight and high load capacity. A common use is in rocker pivots on cars with inboard suspension. In order to achieve rated capacity and life, the mating surfaces should have a smooth, hard finish. A Rockwell hardness of C58 will ensure full rated capacity. Using a matching Thin Nadella Thrust Washer or a Thick Nadella Thrust Washer will provide the proper hardness and finish in the axial direction.

Nadella bearings require lubrication before use. A high-quality lithium-based, EP, or synthetic bearing grease is recommended when these bearings are used as suspension pivots. Higher rotational speeds with lower load (such as supporting rotating shafts inside machines) may require oil lubrication.
