INQUIRY

INA is famous for its needle roller bearings. INA needle roller bearings NK and NKI are successful machine elements for the design of radial compact bearing arrangements with very high load carrying capacity. NKI bearings have an inner ring while NK bearing is designed without an inner ring. INA needle roller bearings NK were previously produced up to a diameter of 10 mm with plastic cages, while needle roller bearings NKI were produced up to a bore diameter of 7 mm with plastic cages.

INA needle roller bearings are single or double row units comprising machined outer rings with ribs, needle roller and cage assemblies and removable inner rings. The bearings are available in open and sealed versions. Also, in this bearing NKS28, the roughness and geometrical accuracy of the raceways have been optimized. This gives higher load carrying capacity and longer life.
