FAGNU1015Single Row Cylindrical Roller Bearing, Straight Bore, 75 x 115 x 20 mm, Non-Locating, Brass Cage

Product Description

What this part is

A FAG NU1015M1 single-row cylindrical roller bearing, 75 mm bore, 115 mm outside diameter, 20 mm width. Straight bore, open, machined brass cage, normal precision class, CN internal clearance.

Decoding the designation

NU is the non-locating cylindrical roller design, with guide ribs on the outer ring and a plain cylindrical inner ring. 10 is the dimension series, the light narrow section, and the bore code 15 gives 75 mm. M1 is a machined brass cage variant. Internal clearance is CN and the class is normal.

What these specifications mean in practice

An NU bearing takes radial load only and lets the shaft move axially relative to the housing, which is what the floating position in a two-bearing arrangement needs; the 2.5 mm figure is the axial displacement facility from the central position. The light 10 series keeps the outside diameter and width small for the bore, which suits compact housings and higher speeds, at a lower radial rating than a 02 or 22 series bearing on the same shaft. The machined brass cage is roller-guided and tolerates higher temperature and heavier shock than pressed steel. The plain inner ring separates from the outer ring, so the two halves mount independently.

Interchange guidance

SKF NU 1015 M, NSK NU1015M and NTN NU1015 are same-envelope equivalents. FAG NU1015-XL-M1 is the current-generation designation for the same bearing. FAG NU1015M1.C3 is the same size at greater than normal clearance; FAG NJ1015 is the same size with an inner-ring rib that locates the shaft in one direction.
