Nadella bearings are used in many racecar applications because of their small size, low weight, and high load capacity. The "combination" design features needle rollers arranged axially around the bore for rotation, plus another set of needle rollers arranged radially at one end for thrust. A common use for this style is in rocker pivots on cars with inboard suspension. Two bearings are typically pressed into the rocker from either side, with the radial bearings facing outwards. 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.
