ASQ needle roller bearings are mechanical components with a small radial dimension, a very high load capacity and above all high-speed resistance. Also for this type of bearing, the results obtained depend largely on the design and execution of the assembly, load distribution and alignment between the inner and outer track of the bearing itself. The special attention paid to the hardening and tolerances of the needle rollers has enabled the use of ASQ cages in very heavy-duty applications such as connecting rods.
