INANKX45Combined Needle Roller and Axial Ball Bearing – 45 mm ID, 58 mm OD, 32 mm Height, Single-Direction Thrust, DIN 5429

Product Description

What this part is:

INA NKX45 is a combined needle roller and axial ball bearing to DIN 5429: a radial needle roller row and a single-direction axial ball row in one unit, without end cap. Unit Quantity: 1 Pc. It is one complete unit: the radial needle roller assembly with its outer ring, plus the axial ball row with its washers.

Decoding the designation:

NKX — a radial needle roller row and an axial ball row built into one unit, single-direction axial, to DIN 5429. The design is supplied for oil lubrication.

45 — bore code. Bore Diameter: 45 mm under the needle rollers.

A plain NKX carries no end cap. The NKX45-Z execution adds one.

Searchable forms of the designation: NKX45, NKX 45, NKX-45, NKX45-XL, NKX45XL.
