INA needle roller / axial deep groove ball bearings do not have an inner ring and are therefore particularly compact in a radial direction. However, they require a shaft raceway that is hardened and ground.
INA combined needle bearings NX and NX..-Z have a full complement axial ball bearing component and end caps.
Series NKX and NKX..-Z have an axial bearing component comprising a ball and cage assembly with a sheet steel or plastic cage. NKX..-Z also has an end cap on the axial bearing component.
For lubrication, the outer ring of INA needle roller / axial deep groove ball bearings has a lubrication groove and lubrication holes.
INA bearings NX and NKX are lubricated with oil. The end cap in NX has lubrication holes.
INA bearings NX..-Z and NKX..-Z are lubricated with grease. The axial bearing component is greased using a lithium complex soap grease to GA08. The end caps do not have lubrication holes.
