About needle bearing:
Needle bearings are a standard element of a rotational motion system. Needle bearings are used in appliexcavatorions where high load capacity, high precision and small overall dimensions are required. Nadella offers a big range of needle bearings. The strength of Nadella’s production consists also in the ability of producing special items at a reasonable price. Every bearing contains the long experience acquired from Nadella through decades of design, production and appliexcavatorion.
